Enhanced ACT: format and scoring

Verified

In short

The shorter enhanced ACT: English, Mathematics and Reading as the core test, with Science and Writing optional.

The ACT (Enhanced ACT)

The Enhanced ACT is a fixed-form, non-adaptive multiple-choice test with three core sections — English, Mathematics and Reading — plus an optional Science section and an optional Writing essay. The core test is 131 administered questions in 125 minutes, of which 108 are scored and 23 are embedded unscored field-test items; adding Science gives 171 administered questions (142 scored) in 165 minutes. Every section is scaled 1-36, and under the enhanced format the Composite is the rounded average of English, Mathematics and Reading only: Science feeds a separate STEM score and Writing (2-12) feeds an ELA score. Math answer choices were reduced from five to four, calculators are permitted on Mathematics only, and there is no penalty for wrong answers.

Online testing provides the Desmos on-screen calculator and examinees may still use a permitted personal calculator instead. Any 4-function, scientific or graphing model is allowed unless it is on ACT's prohibited list; computer algebra system (CAS) models are banned (e.g. TI-89/TI-92 model families, HP Prime, Casio ClassPad). No formula sheet is provided.

Navigation rules

What you may and may not do once a section has started. Our timed practice enforces these on the server, not just in the interface.

  • You can move backward and forward freely within a section.
  • You can change an answer before the section is submitted.
  • A review screen lists your answers at the end of the section.
  • You can mark any question for review.
  • Once a section is submitted it cannot be reopened.

Reported scale
ACT Composite (1-36): 1–36Each section generates a 1-36 scale score. Under the enhanced format the Composite is the average of the English, Mathematics and Reading scale scores only, rounded to the nearest whole number (fractions below one-half round down, one-half or more round up). Science is reported separately on 1-36 and is excluded from the Composite; the optional Writing test is reported separately on 2-12. This records the real reported scale as a fact about the exam — we do not produce a score on it.
  • Raw score is the count of correct answers: "The number of questions you answered correctly on each test section is a raw score."
  • There is no penalty for incorrect answers and no penalty for guessing. Omitted answers score zero — neither penalised nor rewarded — but are tracked separately from wrong answers for analytics.
  • Maximum raw scores under the enhanced format are the scored-item counts: English 40, Mathematics 41, Reading 27, Science 34. Embedded field-test items are excluded from scoring.
  • Reporting-category subscores are the sum of correct answers within each category code: English POW + KLA + CSE = 40; Mathematics PHM + IES = 41; Science IOD + SIN + EMI = 34.
  • The Mathematics Modeling category is an overlay: each modeling item is also counted in its content reporting category, so category shares do not sum to 100%.
  • STEM score = average of Mathematics and Science, awarded only if the optional Science section is taken. ELA score requires English, Reading and the optional Writing section.
  • Superscore Composite is also English/Mathematics/Reading only. Science superscores are still reported and still feed STEM, but not the Superscore Composite.
  • Writing is scored 2-12 as the rounded average of four domain scores (Ideas and Analysis, Development and Support, Organization, Language Use and Conventions). We never auto-score an essay; the rubrics are shown for self-assessment.
  • Our sectional practice contains no embedded field-test items, so every administered question counts toward the raw score we report. Real ACT raw scores exclude 10 English, 4 Mathematics, 9 Reading and 6 Science items.

Why we do not give you a scaled score

ACT converts each section raw score to the 1-36 scale using a FORM-SPECIFIC conversion table built from unpublished equating methodology and item-level IRT parameters. ACT publishes conversion tables only for particular released practice forms, and those tables are valid for those forms alone — they cannot be applied to an original question bank. With no published raw-to-scale method there is no defensible way to estimate a section score, a Composite, a STEM score or an ELA score, so we report raw score, percent correct, per-reporting-category accuracy and pacing instead. ACT percentile ranks and national norms for the enhanced Composite are likewise not published and are suppressed entirely.

What ACT Education Corp. does not publish

We could not verify the following from an official source. Rather than guess, we switch off any feature that would depend on them, and we say so here.

  • Exact duration of the "short break" between Reading and the optional Science/Writing sections on national test dates, and whether any break exists between Mathematics and Reading under the enhanced format. ACT's online student tutorial still describes the legacy pattern (15-minute break after mathematics, 5-minute break after science), which contradicts the February 2026 design framework. Exam-accurate break timing is disabled; no blueprint schedules a timed break.
  • Whether the paper (offline) administration permits the same free within-section navigation and review as the online TestNav interface. The navigation rules encoded here come from the online student tutorial; no official statement was located for paper. Navigation is therefore not presented as mode-specific.
  • The exact split of English items between short and long passages, and the number of passages per English form. ACT states the enhanced English test features "a mix of short and long essays" but does not publish the counts.
  • Number of Reading passages per form. ACT confirms passage lengths (two of roughly 750 standard words, one of roughly 650) and a paired/synthesis element, but does not state a fixed passage count for the enhanced form.
  • Number of Science passages per form and the enhanced-format split across Data Representation / Research Summaries / Conflicting Viewpoints. The 25-35% / 45-60% / 15-20% figures on ACT's science description page are not restated in the February 2026 design framework and may be legacy.
  • Placement of the Reading skill area "Visual and Quantitative Information" under a specific reporting category. ACT's source table does not assign it unambiguously; it is filed under Integration of Knowledge and Ideas here as an inference.
  • Raw-to-scale conversion tables, the equating/pre-equating methodology and the item-level IRT parameters behind them. Published only for specific released practice forms, never in general.
  • The operational blueprint constraints ACT uses to assemble a form (difficulty targets, depth-of-knowledge distribution, passage-type mix beyond the published percentage ranges, matrix-sampling tier assignments).
  • The positions of embedded field-test items within an operational form. ACT says they are "placed strategically throughout the section tests" but does not disclose the placement rule; the clustering seen in one released practice form is form-specific.
  • Writing essay scoring beyond the published domain rubrics: the rater model, adjudication rules and any automated-scoring engine behaviour are not documented in a way that permits replication.
  • Percentile ranks and national norms for the enhanced Composite. Not published in the sources verified, so ACT percentiles are never displayed.
  • Whether Science can be selected or deselected after registration, and the precise registration-time mechanics for choosing Science/Writing on national test dates.
  • Accommodation timing multipliers (50% / 100% extended time) under the enhanced format.
  • Whether international (non-US) test dates in the 2026-2027 cycle are offered in both paper and online modes, and what the February 2026 "additional enhancements for international test takers" consist of.
