Praxis 8005 Science: What the Test Covers and How to Prepare
Praxis 8005 — officially Elementary Education Fundamentals: Science — is the science test in ETS's redesigned Elementary Education Fundamentals family. It is a 90-minute, 74-question selected-response test covering Earth and space science, life science, and physical science, with an on-screen scientific calculator provided[1][5].
Two things make this test unusual. The first is the timing: at 90 minutes it is the shortest of the five Fundamentals tests — the other four run 100 minutes — so 8005 gives you roughly 73 seconds per item, the tightest pace in the family[1][5]. The second is the item mix. Science items lean on data displays and experimental design more heavily than the other subjects do, and both of those formats punish candidates who know the content but misread a table or confuse a control group with a controlled variable.
This page explains what the test covers, who it is for, how it is scored, and how to confirm whether it is the test you should register for. It also includes a free 30-question practice mini test in which every wrong option carries its own explanation — not just the correct answer.

How many 8005 questions fall in each of the three domains is the one fact on this page we cannot verify against an official source. ETS's 8005 test page does not list per-domain counts, and the part of ETS's partner brochure that carries them is cut off in our archived copy[4][7]. Two independent third-party study sites agree on a split close to even thirds, which is why we describe the domains as roughly balanced — but that is third-party triangulation, not an ETS figure, so we publish no per-domain question numbers for 8005[7]. Any page that hands you exact 8005 domain counts is repeating third-party numbers and presenting them as official.
Everything else in the table above — the 90 minutes, the 74 questions, the calculator, the fee, the scale — is published by ETS and verified[1][2][3][5].
Is Praxis 8005 the Right Test for You?
This is the most important question on this page, and it is not one we can answer for you.
Praxis 8005 is the science content test for elementary certification in the 8000 series. Candidates who need it are typically in one of these situations:
- Their state requires a separate elementary science content test and has adopted 8005 for that purpose.
- Their educator preparation program requires it as a program completion or exit requirement.
- They are adding an elementary endorsement that names a science content test.
- They are currently preparing for the 5005 science subtest and need to know whether their state has moved to 8005 before they register.
What we can verify, and what we cannot. We have verified the adoption status of Praxis 8005 in two states. In both, 8005 is the test used, and both publish a qualifying score for it:
| State | Status of Praxis 8005 | Qualifying score |
|---|---|---|
| West Virginia | Listed on the state's ETS requirements page[2] | 143 |
| Arkansas | Listed on the state's ETS requirements page[3] | 126 |
For the remaining 48 states, adoption status is not verified. We do not publish adoption claims we have not confirmed against a state agency or an ETS state requirements page, because a wrong answer here costs you a test fee and a testing window. That is also why you will not find a "states that require 8005" list on this page beyond these two.
How to confirm your test code in about five minutes:
- Open your state's ETS requirements page:
https://praxis.ets.org/state-requirements/<state>-tests.html. (State names are written as one word, no hyphen —westvirginia, notwest-virginia.) - Search the page for Science, and note which code appears. If you see 5005, you are on the old series; if you see 8005, you are on the new one. Note the qualifying score next to the code.
- If the page lists both codes, or is ambiguous, contact your educator preparation program or state licensing agency and ask which code applies to your certification pathway.
If you are unsure after all three steps, do not register yet. The fee is $79.00 and retake windows are limited[1].
What Praxis 8005 Actually Tests
8005 covers science content at the level an elementary teacher has to teach it, plus the practices scientists and engineers use to build and test knowledge. The three content domains are Earth and Space Science, Life Science, and Physical Science[7]; on top of them, roughly 10–15% of items are written as science and engineering practice items, which means the task is to reason about a procedure, a data set, or a design rather than to recall a definition[4][5].
The practice items are distributed inside the three domains, not collected in a separate section. In practical terms, an item that looks like a life science question is often really asking whether you can read a data display or identify what a fair test would have to hold constant.
Earth and Space Science
Earth as a set of interacting systems: the water cycle, weather and climate, Earth materials and the rock cycle, surface processes, plate tectonics, and the Earth–Moon–Sun system.
Typical question shapes:
- Explain a pattern in daylight, shadow length, or temperature using axial tilt rather than distance from the Sun.
- Order weathering, erosion, and deposition from a described scenario, or name the process that produced a feature.
- Read a data table of temperature, rainfall, or daylight and state only the conclusion the data support.
- Identify the evidence that supports plate movement, and separate it from evidence about something else.
Life Science
From cells to ecosystems: cell structures and their functions, heredity and inherited versus acquired traits, life cycles, energy flow and matter cycling in ecosystems, and how populations change over generations.
Typical question shapes:
- Match a cell structure to its function, especially the chloroplast/mitochondrion pair and the structures that are easy to confuse with them.
- Distinguish a trait coded by genes from one produced by the environment during an organism's life.
- Read a food chain, food web, or energy table and describe how energy changes across trophic levels while matter cycles.
- Explain a population change in terms of survival and reproduction, rather than in terms of need or intent.
Physical Science
Matter and its changes, conservation of matter, forces and motion, energy forms and transformations, waves and sound, electricity, and magnetism.
Typical question shapes:
- Decide whether evidence points to a physical or a chemical change, and say why the tempting alternative is wrong.
- Explain what happens to mass in a closed system versus an open one.
- Read a distance–time table or a heating curve and describe the motion or the state change it shows.
- Compare series and parallel circuits, or match a wave property to what an observer hears or sees.
Science and engineering practices (about 10–15% of items)
ETS describes 10–15% of the Fundamentals items as Tasks of Teaching, and for 8005 that overlaps with a second published feature: content that integrates science and engineering practices[4][5]. Expect items that ask you to evaluate a plan, spot the flaw in an investigation, choose the measurement that would settle a question, or decide which conclusion the evidence will bear. These are the items where candidates who memorized definitions lose points to candidates who can reason about a procedure.
A note on what we are not telling you. ETS publishes the domain names, the overall item count, and the SEP percentage. It does not publish, in any source we could verify, a per-domain question count or a sub-skill-level weighting for 8005[4][7]. The "typical question shapes" above are our professional reading of the domain definitions, not an ETS item list. Treat them as orientation, not as a specification.
Data, Graphs, and Experimental Design: How We Write and Explain Every Practice Item
Most practice banks tell you whether you were right. In science that is not enough, because the item you missed usually has a specific, nameable reason: you read the trend backwards, you treated a controlled variable as a control group, or you answered from a misconception you did not know you were carrying.
So every item in our 8005 bank carries an explanation for the correct option and a separate explanation for each of the other options, written to name the misconception that option represents rather than to say that it is incorrect. Here is the format, using a real item from the bank:
| Part of the item | What the learner sees |
|---|---|
| Stem | Two identical trays are filled with the same soil and set at the same slope. Tray 1 is left bare and Tray 2 is planted with grass. The same volume of water is poured onto each tray, and the soil that washes off is collected and weighed. In this investigation, which factor is the independent variable? |
| Correct option | Whether the soil surface is covered by grass or left bare |
| Why it is correct | The independent variable is the factor the investigation deliberately changes, which here is grass cover. The mass of soil washed off is the dependent variable, because it is the outcome that is measured. Water volume and slope are controlled variables, held the same in both trays. |
| Why "the mass of soil collected" is wrong | Names the outcome that is measured, which makes it the dependent variable rather than the factor the setup deliberately changes. |
| Why "the volume of water" is wrong | Names a condition deliberately held the same in both trays, which makes it a controlled variable rather than the tested factor. |
| Why "the slope" is wrong | Names another condition held constant across the trays; matching slopes are what keep the comparison fair. |
Reading a data display: what the item is really testing
Data-display items in 8005 are built so that one option is a conclusion the data actually support and the others are conclusions the data nearly support. The near-misses are usually one of four kinds:
- Overreach. The data show a trend inside the range measured; the option claims something about years, places, or conditions that were never measured.
- Reversal. The option describes the relationship backwards — the row that falls is described as rising.
- Wrong quantity. The option talks about matter when the data are about energy, or about average when the data are about totals.
- One row ignored. The option generalizes from three rows of a table when the fourth contradicts it.
Read the title, then the axes or column headings and units, then the trend, then — before you look at the options — state the conclusion to yourself in one sentence. An option that needs a second sentence to be true is usually the trap. Our seven data-display items are written so that this habit is what separates the correct option from the near-miss.
Experimental design: variables, controls, and fair tests
Experimental design items are the most mechanical items on the test, and also the ones candidates most often get wrong, because four terms that sound alike mean four different things:
| Term | What it means | The mistake it gets confused with |
|---|---|---|
| Independent variable | The one factor the investigator deliberately changes between conditions | Confused with the outcome that is measured |
| Dependent variable | The outcome that is measured, and that is expected to respond to the change | Confused with the factor that was changed |
| Controlled variables | Every other condition that is deliberately held the same across all conditions, so the comparison is fair | Confused with the control group; these are conditions, not a group |
| Control group | The untreated baseline condition that the treated conditions are compared against | Confused with the controlled variables, or mistaken for the largest dose |
Three rules cover almost every design item you will see:
- One thing changes. A fair test changes one factor and holds everything else constant. If two factors change at once, the cause of any difference cannot be identified — that is what makes an item's proposed "improvement" wrong.
- Controls are conditions; a control group is a group. "The same temperature in every dish" is a controlled variable. "The dish with no salt added" is the control group, and it is the baseline the treated dishes are measured against.
- Replication counts. Repeating trials within a condition, or testing many seeds or subjects per condition, makes a result more reliable. It does not replace holding the other conditions constant, and it does not turn a confounded design into a clean one.
Our three design items are built on exactly these rules, and — this is the part most banks skip — the wrong options are the specific design errors: changing two factors at once, calling a controlled variable the control group, or fixing the design by adjusting the measurement instead of the setup.
The misconceptions we build wrong options around
Science items are unusually good at catching prior knowledge that is wrong rather than missing. These are the misconceptions our 8005 bank targets, each one attached to the specific item whose wrong option it explains:
| Misconception | The scientifically accurate statement |
|---|---|
| Seasons are caused by Earth being closer to the Sun in summer | Seasons are caused by Earth's tilted axis, which changes the angle and the duration of sunlight a hemisphere receives. Orbital distance varies too little to drive them. |
| Moon phases are caused by Earth's shadow falling on the Moon | Phases come from seeing different portions of the Moon's sunlit half as it orbits Earth. Earth's shadow reaches the Moon only during a lunar eclipse. |
| Heavier objects fall faster | With no measurable air resistance, objects fall at the same rate regardless of mass: the larger force on a more massive object acts on a proportionally larger mass. |
| Plants respire only at night, or not at all | Plants respire continuously, day and night. Photosynthesis happens only in the light, and it usually outpaces respiration during the day. |
| Matter disappears when something dissolves, fizzes, or burns | Matter is conserved. In an open system the missing mass has left as a gas; in a closed system the total mass does not change. |
| Energy is used up, or is recycled in an ecosystem | Matter cycles; energy flows. Energy enters mainly as sunlight and much of it is released as heat at every step, so it is not reused. |
| Individual organisms adapt because they need to | Variation already exists in a population. Selection changes which variants survive and reproduce, so the population shifts across generations. |
| Steady increase in distance means the object is accelerating | Equal distances in equal times mean constant speed. Acceleration means the distance covered in each equal interval is itself changing. |
| A flat stretch on a heating curve means heating stopped | During a change of state, added energy goes into breaking the arrangement of the particles instead of raising the temperature. |
| Weather and climate are the same thing | Weather is short-term atmospheric condition; climate is the long-term pattern for a region. One cold winter does not test a multi-decade average. |
Three further rules govern the bank, and they exist because science is a subject where a prep site can be quietly wrong in ways that cost points:
- Standard textbook framing on contested topics. Where a topic has a settled scientific treatment in U.S. elementary and secondary science standards — natural selection, the age of Earth, the evidence for a warming climate — our items use that treatment and stop there. Items do not ask candidates to take a political or religious position, and they do not editorialize about one.
- No third-party summaries as sources. Content is written to the official domain names and to standard reference science. Where the only available basis is third-party — as it is for the 8005 domain split itself — we say so on the page rather than presenting it as official.
- Fact-check flags stay visible. The 30 items behind this page are machine-drafted and have not
yet been through human fact-checking. Each one carries
review_status: draftuntil it has, and the contact page is open for corrections to any figure on this page.
How Praxis 8005 Differs from Praxis 5005
Candidates who prepared for the older science subtest will find the content familiar. What changed is the test family, the length, the format of the domain reporting, and the calculator policy:
| Praxis 5005 | Praxis 8005 | |
|---|---|---|
| What it is | Science subtest within Elementary Education: Multiple Subjects (5001) | Standalone test in the Elementary Education Fundamentals family |
| Questions | 55[7] | 74[1][5] |
| Time | 55 minutes[7] | 90 minutes[1][5] |
| Pace | About 60 seconds per item[7] | About 73 seconds per item[1][5] |
| Content domains | Earth and Space Science · Life Science · Physical Science, described as close to evenly weighted[7] | The same three domains. ETS publishes no verifiable per-domain item count for 8005, so we give none[7] |
| Calculator | An on-screen scientific calculator is provided[7] | On-screen scientific calculator provided[1] |
| Fee | $64 as a subtest of the multiple-subjects test[7] | $79.00 as a standalone test[1] |
| Modular category retakes | Not available | Praxis Steps lists 8501 / 8502 / 8503 for 8005[2] |
| Legacy status | Retires with the 5000 series in 2028-08[2][3] | Current test in the 8000 series[1][5] |
Four practical consequences:
- Nineteen more questions and thirty-five more minutes. The pace per item actually loosens slightly — about 73 seconds instead of about 60 — but the item pool is broader, so the extra time is not spare time. Plan to spend it on the data and design items.
- No per-domain weighting to plan against. With 5005, third-party guides repeat an even split, and we can quote it as approximate. For 8005, the per-domain counts are not verifiable against an official source, so the honest planning assumption is three domains of roughly equal size: do not skip one, and do not over-invest in one on the strength of a number nobody can source.
- The calculator is still provided. That is worth rehearsing. The on-screen scientific calculator is available for 8005, and very few items need it, so the risk is being slowed down by an unfamiliar interface rather than by the arithmetic itself[1].
- Do not treat the codes as interchangeable. They are different tests with different registrations and score reporting. If your state still lists 5005, prepare for 5005; if it has adopted the 8000 series, prepare for 8005[2][3].
If you are working from the older guide for the previous series, that guide is still the right place to review the science content itself: Praxis 5005 Science study guide — its domain breakdowns, misconception alerts, and graph-reading routine cover the same material. Just match your practice to the code your state actually requires.
Practice: Free Praxis 8005 Mini Test
A 30-question mini test with ten items in each of the three official content domains, built to the domain names above. It includes three multiple-select items written in the "Which TWO of the following" format used by the official samples in this family, seven data-display items, and three experimental design items. Every item carries an explanation for the correct option and for each wrong option, plus a domain-level result breakdown. It loads below — enable JavaScript to take it.
First administration of 8005 was 2026-03-09 and score reporting began 2026-04-17[1][5]. Until the test loads, you can:
- Read the official test page for Praxis 8005 and confirm the current fee, format, calculator policy, and any testing window restrictions[1].
- Check whether your state has adopted 8005 using the link pattern under "Is Praxis 8005 the Right Test for You?" above.
- Work through the longer practice set: Praxis 8005 practice test.
- Review the science content against the previous series: Praxis 5005 study guide, or browse the whole family at the Praxis 8000 series hub.
Scoring: What You Can and Cannot Predict
Praxis 8005 is scored on a 100–200 scale[6]. Your qualifying score is set by your state licensing agency or preparation program, not by ETS and not nationally[2][3]. The two 8005 values we have confirmed are West Virginia's 143 and Arkansas's 126[2][3]; confirmed qualifying scores across the 8000 series run from 126 to 152, so 8005's verified values sit at the bottom of that range.
Two claims circulate online that are wrong, and that we do not repeat:
- That the 8000 series uses a 100–300 scale with a 240 passing score. It does not. The scale is 100–200, and the verified qualifying scores in the 8000 series sit between 126 and 152[2][3][6].
- That there is a single national cut score for 8005. There is not. Any page that gives you one number without naming a state is guessing[2][3].
Because there is no public official conversion table from raw items to scaled score for Praxis 8005, we do not offer a scaled score calculator for this test. A practice percentage is a practice percentage. Presenting it as a predicted scaled score would be a fabrication, and it is the kind of number people make registration decisions on.
Frequently Asked Questions
What is Praxis 8005?
Praxis 8005 is Elementary Education Fundamentals: Science, a 90-minute, 74-question selected-response test on science content for elementary teachers. It is part of the 8000 series and first administers on 2026-03-09[1][5].
What does Praxis 8005 cover?
Three content domains: Earth and Space Science, Life Science, and Physical Science. ETS does not list a per-domain question count for 8005 on the official test page, and the section of ETS's partner brochure that carries it is truncated in our archived copy, so we describe the three domains as roughly equal in size and publish no per-domain numbers. In addition, roughly 10–15% of items integrate science and engineering practices[4][5][7].
Is Praxis 8005 the same as Praxis 5005?
No. 5005 is the Science subtest of the Elementary Education: Multiple Subjects test (5001), listed at 55 questions in 55 minutes. 8005 is a standalone test in the 8000 series at 74 questions in 90 minutes. Both cover elementary science, but they are different tests with different registrations, timings, and score reporting[7].
Which states require Praxis 8005?
We have verified two states. West Virginia lists 8005 with a qualifying score of 143, and Arkansas lists 8005 with a qualifying score of 126[2][3]. Adoption status in the other 48 states is not verified, and we do not publish unverified adoption claims. Check https://praxis.ets.org/state-requirements/<yourstate>-tests.html before registering.
What is the passing score for Praxis 8005?
There is no national passing score. Each state sets its own qualifying score. Confirmed 8005 values are 143 in West Virginia and 126 in Arkansas[2][3]. Your state's ETS requirements page is the authoritative source.
Can I use a calculator on Praxis 8005?
Yes. ETS provides an on-screen scientific calculator for 8005, as it does for 8003 Mathematics[1]. Familiarize yourself with its functions before test day rather than meeting it for the first time under time pressure — very few 8005 items need it, and the ones that do are usually unit conversions or simple calculations.
Does Praxis 8005 include multiple-select questions?
Every 8005 item is selected-response. Within the 8000 series, ETS's published multiple-select samples use the wording Which TWO of the following, and our 8005 practice bank includes three items in that format so the wording does not surprise you. We have not seen an official 8005 sample item list confirming that format appears on this test, so treat it as a possibility rather than a certainty[4].
When are scores released for Praxis 8005?
Score reporting for the Elementary Education Fundamentals tests began 2026-04-17[5]. Check the official test page for the release schedule that applies to your test date, because reporting dates are specific to each administration window[1].
Is this free practice test official?
No. Learndiag is an independent study tool and is not affiliated with ETS. Practice questions are original, written to the official content domain names published by ETS, and are not official ETS test items[1].

Notes on source limitations — read these before relying on the page:
- The 8005 per-domain item counts are the single unverified field in our facts library. ETS's test page does not list them, and the brochure page that carries them is cut off in our archived copy. Two independent third-party sources agree on a split close to even thirds; we treat that as triangulation and publish no per-domain numbers for 8005. Note that our own sibling page comparing 5001 with the 8000 series states an approximate 8005 split, sourced the same way — if you see a percentage there, it rests on the same third-party agreement, not on an ETS figure[4][7].
- ETS publishes three different launch windows for the 8000 series. The partner brochure says "Spring 2026"; another ETS PDF says "Summer 2026"; the official test pages say "September 2026" for 8002–8005. The inconsistency is ETS's, not a transcription error, so this page states the Steps codes for 8005 but no Steps date. Confirm the current window on the official test page and see Praxis Steps explained before you plan a category-by-category retake[1].
- Source 4 has no public URL. It is distributed to ETS educational partners. We archive our copy rather than cite a URL that does not exist.
- Source 7 is where the domain names come from, and it is not an ETS document. We use the domain names because two independent sources agree on them and they are consistent with the Steps names ETS publishes for 8005 (8501 Earth and Space Sciences, 8502 Life Sciences, 8503 Physical Sciences — note the plural in the Step names versus the singular domain names). Treat any per-domain percentage for 8005 as an estimate.
- 48 states remain unverified. This is a deliberate gap, not an oversight. Only West Virginia and Arkansas are confirmed for 8005.
- The practice bank is flagged as unreviewed. All 30 items carry
review_status: draftand have not been through human fact-checking. Physical units, conversion factors, and the illustrative data values inside the practice tables should be confirmed by a human reviewer before any of it is treated as final. Treat the items as practice, and tell us if one of them is wrong — we correct errors and note the correction.
Figures we deliberately do not publish. Five things were left off this page because we could not confirm them: the per-domain question count for 8005; the number of items ETS fields in any single administration window; a raw-to-scaled conversion table; the qualifying scores of the other 48 states; and a sub-skill-level blueprint for any of the three domains. Where a competing site gives you one of these without naming an official source, treat it as an estimate.
