TEAS Study Guide: Four-Domain Foundations and a 14-Day Plan

Know what this Version 7 guide actually prepares

ATI’s Test of Essential Academic Skills assesses academic foundations for health-science applicants. Its current Version 7 structure has four areas: Reading, Mathematics, Science, and English and Language Usage. ATI lists 170 total items with 209 minutes of allocated testing time. The outline distinguishes 150 scored items from 20 unscored pretest items. Those are two different counts of the same examination, not competing versions of its length.

The official scored allocation is 39 Reading, 34 Mathematics, 44 Science and 33 English items. Section testing times are 55, 57, 60 and 37 minutes respectively. Our twelve cases deliberately give three to each broad area so a learner can explore different reasoning errors. That even distribution is an editorial choice; it is not an exam blueprint, a full-length simulation or a basis for converting twelve answers into an official score.

Actual question formats extend beyond four-option multiple choice. ATI lists multiple select, numeric fill-in, hot spot and ordered response as well. This pilot’s questions practise selected concepts and explanations only. A learner still needs appropriate experience responding in those other formats and much broader content study. This guide does not supply official secure items, clinical-care instructions, a recognised course completion or an admissions guarantee.

Worked application: a fictional learner completes all twelve cases correctly and labels the record “full ATI TEAS completed.” The record’s support is narrower: twelve selected four-option cases were completed in this pilot. The official exam has 170 total items and additional response formats, so neither the full-exam completion claim nor an official-score claim follows. Replace the label with the actual practice performed and list the unpractised content and formats. Correct answers are useful evidence about these cases, not evidence that omitted tasks were attempted.

The ten local units below are sections of this actual guide. Their IDs are not links to pre-existing ATI lessons on OpenExam. Read their examples, attempt the original cases and retrieve the cards; then use the remaining-gap list to plan further academic work. Source dates, independent review and qualified educator review are different kinds of evidence. Qualified educator review remains pending.

Keep a passage’s claim and its limits together

Reading begins with what the words actually establish. A main-purpose answer should cover the central action and its relevant limits. An inference should follow from supplied statements without importing an attractive outside story. ATI’s outline includes summarising, making inferences, interpreting purpose and using textual evidence. That scope supports the learning target; the following notice and deductions are newly authored, not adapted ATI questions.

Original worked passage: “The garden archive will move its fragile maps to a dry cabinet during wall repairs. Visitors may still view digital copies at the front desk. Staff have not yet set a date for returning the paper maps to the display. The repair will be reviewed after the first week.” A defensible main-purpose summary is that access to a collection is changing during maintenance. It retains the continuing digital access and the uncertainty about a return date.

The passage does not establish that the paper maps have been destroyed, that digital copies are permanently superior, or that a first-week review guarantees a return that week. Those claims use words related to the passage while changing what it says. To inspect an option, identify its action, time, strength and subject. A statement about a review is not automatically a statement about a completed repair. A statement about one collection is not automatically a statement about the whole archive.

For a worked inference, ask whether a visitor can rely on seeing the paper originals next week. The supplied notice does not establish that availability; the return date is unset. This is a limit on the conclusion, not proof of indefinite closure. Write one supporting phrase and one condition that would have to be added for the stronger claim. That exercise makes a wrong option informative instead of treating a familiar topic word as evidence.

Explain sentence roles and combine sources condition by condition

A sentence can add an example, explain a cause, mark a contrast or narrow an earlier statement. Naming its role requires reading both the sentence and its neighbours. In the original pair “Digital copies remain available. Unlike the wall display, they can be searched by date, ” the second sentence contrasts a feature. It neither explains why the repairs began nor claims that every collection has been digitised. The contrast is local to the two stated forms of access.

Integrating a notice and a table requires keeping each source’s conditions. Consider this newly written temporary-service table in words: scanned-map access—Tuesday and Thursday, 11:00–15:00; request pickup—Monday through Friday, 10:00–16:00. An accompanying notice says the wall display is closed this week. On Thursday at 12:00, both listed temporary services are within their stated schedules; the closed wall display is not. On Wednesday at 12:00, pickup is supported but scanned-map access is not listed.

The time alone is insufficient. A day condition, time condition and closure condition can all matter simultaneously. When an option combines services, check each component separately rather than approving the bundle because one service is available. A useful scratch table has one row per service and columns for day, time and overriding notice. This table is a reasoning aid for the fictional source material, not an asserted policy at any real institution.

ATI’s reading outline specifically includes applying information in visuals and integrating sources in different formats. Here the learning operation is connecting explicit facts, not inventing a reason for the timetable. A later timetable could change the answer; a personal expectation of normal opening hours cannot change the given one. Distinguish a statement contradicted by the sources from one simply not established by them.

Name the whole before using a ratio or percentage

A ratio compares quantities in a stated order. A part-to-part ratio and a part-to-whole fraction are different descriptions. In a new workshop example, red and clear materials have an additive-volume ratio 2:7. A 900 mL batch contains nine equal parts, so each part is 100 mL; red accounts for 200 mL and clear for 700 mL. Red:clear is 2:7, but red:total is 2:9. Multiplying the total by 2/7 would silently change the meaning of the comparison.

The ratio calculation assumes the exercise’s stated additive volumes. It is not a general claim that mixing real substances never changes volume. Keep assumptions attached to the example. Write units at each step:900 mL divided by 9 parts gives 100 mL per part. Multiplying by 2 parts returns 200 mL. If a question asks litres instead, convert the final unit deliberately; do not report the same numerical value with a different label.

A percent is a ratio expressed per hundred. In an original attendance record, 120 people registered, 90 attended and 36 of the attendees completed a questionnaire. Questionnaire completion among attendees is 36/90=40%. Completion among all registrants is 36/120=30%. Both calculations are valid answers to different questions. The phrase after “of” often identifies the base, but the full wording decides which group is requested.

Before calculating, write a sentence identifying the requested numerator and denominator. Afterward, check whether the result describes the same population and quantity. A numerator of attendees cannot answer a question about questionnaire completion merely because it produces a convenient percentage. These academic calculations use fictional data, not drug dosing, treatment or personal financial recommendations. ATI’s mathematical scope includes ratios, rates, percentages, measurement and data; this unit covers selected examples within that larger range.

A changed extreme value can affect summaries differently

The arithmetic mean is the sum divided by the number of observations. The median is found from the ordered data: the middle value for an odd count, or the average of the two middle values for an even count. These operations summarise different aspects of a record. A data question may ask for either, so choose the specified operation before deciding which answer looks typical.

Original worked records:2, 3, 3, 4, 28. Their sum is 40, so their mean is 8; their median is the third ordered value, 3. Suppose a documented audit establishes that 28 should be 8. The new sum is 20 and mean is 4, while the ordered middle value stays 3. A correction can therefore change the mean without changing the median. The calculation is not an instruction to delete an inconvenient observation: the audit supplies a reason to replace this particular entry.

For six ordered values 2, 3, 3, 4, 8, 10, the two middle positions are third and fourth. The median is(3+4)/2=3.5, even though 3.5 is not itself an observed value. This is another reason to use ordered position rather than choose the largest, most frequent or most recently corrected entry. Always state the unit inherited from the original measurement; a summary of lengths remains a length.

OpenStax explains why a median is less sensitive than a mean to the precise size of an extreme value. That does not make one measure universally best or establish that an extreme value is erroneous. In this pilot, the learning target is choosing and explaining the requested summary, checking arithmetic and retaining the record’s provenance. ATI also assesses wider statistical information and variable relationships that this short unit does not fully cover.

Trace feedback direction and each substance’s gradient

Physiology questions often describe a system rather than ask for an isolated word. Homeostasis involves regulation around a reference range. In a negative-feedback model, a change triggers a response that counteracts the deviation. A sensor detects a value, a control centre compares information with the reference, and an effector produces a response. “Negative” describes that relationship; it does not mean harmful, absent or numerically less than zero.

For an original nonclinical model, let a regulated value rise above its reference range. A sensor reports the rise, a controller increases removal, and the value falls back toward the range. The last relationship is compensatory. If the response instead amplified the initial rise, that direction would not fit this negative-feedback description. This abstract model helps read human physiology explanations; it does not diagnose a person or specify a treatment, target measurement or care procedure.

Membrane movement requires a different kind of directional reasoning. For a permeant substance undergoing passive diffusion, initial net movement follows its own concentration gradient from higher to lower concentration. Suppose substance P is 6 units on side A and 2 on side B, while substance Q is 1 on A and 4 on B. With permeability to both and passive diffusion only, net P movement is A→B and net Q movement is B→A. Adding the concentrations of different substances would lose the two separate gradients.

Equilibrium does not mean that individual molecules stop moving. It means no net directional transfer for the substance at equilibrium under the specified conditions. Selective permeability also matters: a concentration difference alone does not establish movement through a barrier that does not permit that substance to cross. This unit supports selected cellular and regulatory foundations. It leaves major anatomy, organ-system, genetics and molecular-biology content for further study rather than presenting these models as full TEAS Science coverage.

Specify what changes, what is measured and what is conserved

A testable explanation leads to a prediction and an observation that can bear on it. In an experiment, distinguish the manipulated input, the measured outcome and factors deliberately held constant. These roles are not determined by which number is largest. A precise outcome description states what is recorded, in which units and over what interval. In this pilot, the scientific-method framework comes from a primary academic textbook; each study design and numerical example is original.

Worked classroom design: two groups of paper strips receive equal water volumes, use the same paper and are measured after the same ten-minute interval. The manipulated factor is strip width, 5 mm versus 10 mm. The recorded outcome is the distance water travelled up each strip in millimetres. Width is not the dependent outcome simply because it differs between groups. Water volume and observation time are controls in this design. This description proposes no clinical experiment and establishes no result before observations are collected.

When interpreting a reported result, keep the conclusion tied to the actual design and measurements. One observed pattern can support an explanation without proving every related claim. A source’s example of a control group is a framework for comparison; it is not permission to assume that every possible difference has been eliminated. This guide’s question asks about variable roles within a fully supplied fictional design, not about a universal biological effect.

Chemical representation adds a conservation check. In the worked equation 2 Mg+O₂→2 MgO, the left side contains two magnesium atoms and two oxygen atoms, and the right side contains the same counts. A coefficient multiplies an entire formula; a subscript is part of a substance’s identity. Changing MgO to MgO₂ would change what substance is represented rather than merely balance the stated reaction. Count atoms on both sides, adjust coefficients and recount. This is symbolic academic chemistry; it is not a laboratory procedure. Acids, bases, atomic structure and many other outlined chemistry topics remain beyond this unit.

Find the subject and the clause before editing punctuation

English editing combines meaning with sentence structure. For subject–verb agreement, identify the head of the subject phrase rather than the nearest noun. In the original sentence “The label on the boxes identifies the collection, ” label is singular; boxes belongs to a modifying phrase. The singular verb identifies agrees with label. In “The labels on the box identify the collection, ” labels is plural, so identify is the appropriate simple-present form.

A tense instruction is a separate condition. If a task requests the simple present, a grammatical past-tense completion may still fail that request. Check number and tense rather than treating every wrong option as the same error. The examples here concern the formal written-English conventions assessed in the stated task. They are not claims that every dialect or every communicative context must use an identical construction.

For punctuation, test whether each word group can stand as a complete clause. Original pair: “The scanner warmed up” and “the operator checked the settings.” Both have a subject and a finite verb and express complete propositions. A semicolon can join them: “The scanner warmed up; the operator checked the settings.” A period can also separate them into two sentences. A comma plus an appropriate coordinating conjunction is another available pattern when the task permits adding one.

A bare comma does not supply the standard connection between those independent clauses. A transition such as however is not itself a coordinating conjunction. Conversely, “While the scanner warmed up” introduces a dependent relationship and cannot stand alone as the complete second sentence in this exercise. Do not select punctuation by the pause heard in your head alone. Name the clause types and then check whether the proposed connection fits both the grammar and the task’s restrictions.

Choose a relation, then choose its words

Paragraph revision asks more than whether a sentence is grammatically possible. The wording should connect the intended ideas without inventing a causal claim, an example or an evaluation. ATI’s English outline includes audience, clarity and well-organised paragraphs. This unit uses a small original draft to practise one part of that wider writing task, not to replace vocabulary, spelling or broader composition study.

Original draft: “The catalogue gives each object its technical name. The family handout explains each object using familiar language.” The two sentences describe different approaches for different text functions. If the revision task explicitly asks to mark that difference, “In contrast” fits. “Similarly” would signal resemblance; “As a result” would assert a causal relationship; “For example” would present the second as an instance of the first. A connector is a claim about a relationship, not decoration.

An editor can also improve clarity by preserving the nouns that make a comparison intelligible. Replacing both catalogue and handout with an unexplained “it” would make the contrast harder to follow. This is an original revision observation about the supplied draft, not a new rule that pronouns should never be used. Read the surrounding sentences before deciding what information can be omitted safely.

In a worked revision explanation, state the intended relation, quote only the small words needed to identify it and show why a competing connector changes that relation. A wrong connector may leave two individually grammatical sentences while altering the argument between them. The diagnostic case therefore specifies the desired relation. It does not ask the learner to guess an author’s unstated preference among several stylistically acceptable drafts.

Use fourteen days to expose gaps and improve explanations

The fourteen-day schedule links only to the real local units, cases and cards in this package. It begins with current scope and reading, introduces quantitative tools before data summaries, then studies the biology and inquiry units. Sentence editing precedes paragraph revision, and the mixed-review unit follows its prerequisite branches. The schedule’s minutes are editorial estimates. They are not measured completion times or a claim that two weeks is enough for every applicant.

Attempt a case without its rationale, then explain all four options. Use a short error record with the requested quantity or relation, the evidence used, the condition missed and a corrected explanation. For mathematics, retain units and denominators. For reading, identify the exact claim supported. For science, trace the stated mechanism or variable role. For English, name the structural or discourse condition instead of relying only on how a sentence sounds.

Worked error record using the earlier workshop example: requested quantity—red volume in the 900 mL total; attempted setup—900×2/7; missed condition—2:7 compares red with clear, not red with the whole; correction—900×2/(2+7)=200 mL; next action—draw nine equal parts and label the two red parts before recalculating. The error is the selected base, not merely a slip in multiplication. A completed record identifies that mechanism so the next attempt can check it explicitly.

The cards require retrieval without options. A complete answer includes the requested distinction and its condition, not merely a familiar label. If the explanation omits a required assumption, mark it incomplete and revisit the relevant worked example. Returning to a known question can show improvement in explanation, but the repeated score is not an independent estimate of readiness or an official scaled score.

After the final review, list remaining current-outline topics and response formats that these examples did not teach. This includes substantial organ-system, chemistry, algebra, geometry, vocabulary and reading work as appropriate to the learner’s gaps. The actual TEAS includes alternate formats, while this pilot provides MCQs only. Continue with suitable current academic instruction and official format information. Admissions decisions and required results are not determined by this twelve-case practice set.
