Based on your ACT9 score profile — targeted, high-impact preparation strategies for your next test date.
The "ACT9" format refers to the full enhanced ACT score report that includes all 9 score types — going far beyond just the composite score that most students focus on. Understanding all 9 scores gives you a complete diagnostic picture of your academic strengths and areas to improve.
The complete ACT enhanced score report for 2025–26 includes the following 9 score categories:
| # | Score Type | Scale | Based On |
|---|---|---|---|
| 1 | Composite | 1–36 | Avg of all 4 core sections |
| 2 | English | 1–36 | 75 questions, 45 min |
| 3 | Mathematics | 1–36 | 60 questions, 60 min |
| 4 | Reading | 1–36 | 40 questions, 35 min |
| 5 | Science | 1–36 | 40 questions, 35 min |
| 6 | Writing (Essay) | 2–12 | Optional essay, 40 min |
| 7 | ELA Score | 1–36 | Avg English + Reading + Writing |
| 8 | STEM Score | 1–36 | Avg Math + Science |
| 9 | Subscores (×7) | 1–18 each | Diagnostic within sections |
| Subscore | From | Tests |
|---|---|---|
| Production of Writing | English | Grammar, mechanics, usage |
| Knowledge of Language | English | Style, conciseness, word choice |
| Number & Quantity | Math | Number systems, proportional reasoning |
| Algebra & Functions | Math | Equations, inequalities, functions |
| Geometry & Statistics | Math | Geometry, probability, data analysis |
| Integrating Knowledge | Reading + Science | Cross-text synthesis, evidence |
| Understanding Complex Texts | Reading | Main idea, inference, structure |
For each of the 4 core sections (English, Math, Reading, Science), enter either your raw score (number of questions answered correctly — no deduction for wrong answers) OR your already-scaled score (1–36) from an official ACT score report. The calculator shows a live scaled preview as you type raw scores. You do not need all 4 sections — partial results are calculated from whichever sections you enter.
If you took the optional ACT Writing (Essay) section, switch to the Writing tab and enter your 4 domain scores (Ideas & Analysis, Development & Support, Organization, Language Use — each scored 2–12) from your official score report. Alternatively, enter your total Writing score directly. The calculator will compute your ELA score if you have English, Reading, and Writing scores entered. If you did not take Writing, skip this tab entirely.
The 7 reporting category subscores (each 1–18) are available on your official ACT score report. Enter them on the Subscores tab for a detailed diagnostic breakdown of your skills. These subscores help identify specific content areas within each section that need the most improvement. They do not affect your composite, section, ELA, or STEM scores — they are additional diagnostic data.
Hit the calculate button to instantly receive all 9 score types — Composite, English, Math, Reading, Science, Writing, ELA, STEM, and all 7 subscores — along with national percentile ranks, college readiness benchmark status (Met/Almost/Not Met), a full score summary table, college tier reference, and personalized score improvement recommendations based on your specific score profile.
The 7 reporting category subscores are the most underutilized part of the ACT score report. If your Math section score is lower than you'd like, the subscores tell you exactly whether it's Number & Quantity, Algebra & Functions, or Geometry & Statistics pulling you down — letting you focus prep time surgically rather than reviewing all of Math. Similarly, a lower English score might be entirely from Knowledge of Language (style/word choice) rather than Production of Writing (grammar mechanics) — which changes your prep strategy completely. Always analyze your subscores before planning your next study session. Official ACT practice with subscore breakdowns is available at act.org/free-prep.
The ACT Writing (Essay) section is graded by two trained human raters who each score your essay on a 1–6 scale across 4 domains. The two raters' scores for each domain are summed (giving a 2–12 range per domain), and the four domain scores are then averaged and rounded to get your final Writing score (2–12 scale).
The 4 Writing domains scored are: Ideas & Analysis (quality and depth of your argument), Development & Support (how well you support your ideas with reasoning and examples), Organization (structure and flow of your essay), and Language Use & Conventions (grammar, vocabulary, style).
Key fact: Your Writing score does NOT count toward or change your Composite score. It is reported as a separate score. If the two raters' scores disagree by more than 1 point on any domain, a third rater resolves the discrepancy.
| Writing Score | Percentile (approx.) | Descriptor |
|---|---|---|
| 10–12 | 96th–99th | Exceptional |
| 8–9 | 77th–93rd | Strong |
| 6–7 | 39th–65th | Average |
| 4–5 | 9th–28th | Developing |
| 2–3 | 1st–5th | Below Average |
The ACT Writing section is optional. As of 2025–26, fewer than 30% of US colleges require or recommend the ACT Writing score for admissions. Here is a practical decision guide:
Check each college's current policy at their official admissions website or use ACT's score-sending tool.
The ELA score is calculated as the average of your English, Reading, and Writing section scores, rounded to the nearest whole number. It is only produced when you take the optional Writing section. The ELA score provides a holistic measure of your English Language Arts skills — combining grammar/mechanics (English), reading comprehension (Reading), and written expression (Writing).
Formula: ELA = (English Score + Reading Score + Writing Score) ÷ 3 (rounded)
Example: English 29, Reading 31, Writing 8 → ELA = (29+31+8) ÷ 3 = 68 ÷ 3 = 22.67 → ELA = 23
Some selective colleges use the ELA score as an additional data point to assess writing-intensive program readiness. The ELA score is also useful for placement in first-year composition and writing courses at many universities.
The STEM score is the average of your Mathematics and Science section scores, rounded to the nearest whole number. It does not require the Writing section. The STEM score is a quick indicator of your readiness for STEM-focused programs and is increasingly used by engineering, pre-med, and data science program admissions offices alongside the composite score.
Formula: STEM = (Mathematics Score + Science Score) ÷ 2 (rounded)
Example: Math 30, Science 28 → STEM = (30+28) ÷ 2 = 29 → STEM = 29
ACT defines a STEM Benchmark score of 26 — a STEM score at or above 26 is associated with readiness for STEM college courses. Many engineering schools and pre-med programs consider STEM scores above 28 particularly competitive in 2025–26.
For students applying to engineering schools (Purdue, Georgia Tech, UIUC, UT Austin), pre-med programs, or data science majors, the ACT STEM score carries increasing weight in 2025–26. A STEM score of 28+ places you in approximately the 87th percentile nationally and signals strong quantitative reasoning. When reporting your ACT scores on engineering program applications, always mention your STEM score alongside your Composite — especially if your Math or Science individual scores are your strongest sections but your Composite is pulled down by Reading or English.
