An ACT raw-to-scaled conversion chart maps how many questions you got right in a section to your 1–36 section score—and every official test form has its own table, so you must use the chart that matches your specific practice test or test date. Learning to read that table is how you turn a bubble sheet into a meaningful practice Composite.
What the chart shows
Each row pairs a raw score (number correct on scored questions) with a scaled score (1–36). You look up your raw count for English, then Math, then Reading, and average those three scaled numbers for your Composite. Science and Writing use separate tables when you take those optional sections.
Sample conversion pattern (Math)
Math has 45 scored questions on the enhanced ACT. A typical table might look roughly like this—notice how the scale is not linear:
- 45 raw → 36 scaled
- 44 raw → 35 scaled
- 42 raw → 33 scaled
- 38 raw → 29 scaled
- 30 raw → 22 scaled
- 20 raw → 15 scaled
Missing one question at the top of the scale often costs a full point; in the middle, several misses may move you only one scaled point. That is equating at work, not a fixed percentage. For why tables differ by form, see is the ACT curved.
English and Reading scale differently
English (50 questions) and Reading (36 questions) have their own columns. A raw 34 on Reading might land near a 32, while the same raw count on English would be far from the top. Never borrow a Math chart for another section or another form.
Where to find official charts
- Official practice tests: each released PDF includes a scoring guide at the end. Start with free ACT practice tests.
- Your score report: after a real test, your report shows scaled scores; you usually do not see the full public table for that form.
- Third-party books: often use approximate scales—treat those as estimates. For how far off they can be, see how accurate ACT practice scores are.
Step-by-step scoring workflow
- Count correct answers per section (exclude experimentals if marked).
- Look up each raw score on that form's table.
- Add English + Math + Reading scaled scores, divide by 3, round.

The bottom line
The conversion chart is form-specific. Count correct, look up each section on the right table, average three sections for Composite—and never assume one chart fits every test.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
