The ACT Composite Score Formula

Composite Score = (English + Math + Reading + Science) ÷ 4, rounded to the nearest whole number

Each of the four ACT sections is scored on a scale of 1-36, and the composite score — the number colleges typically focus on most — is simply the average of all four, rounded using standard rounding rules (0.5 rounds up).

Understanding Scaled Scores

Your raw score (number of questions answered correctly) on each section is converted to a "scaled score" of 1-36 using a conversion table that accounts for slight difficulty variations between different test forms, ensuring scores are comparable across different test dates.

What's a Good ACT Score?

The national average composite score is typically around 19-21, though "good" is relative to your target schools' typical admitted student score ranges — research your specific target schools' average ACT scores for meaningful context.

Frequently Asked Questions

How is my raw score converted to a scaled score?

ACT uses a conversion table (which varies slightly by test form to account for difficulty differences) to convert your number of correct answers on each section into a scaled score of 1-36, ensuring fair comparison across different test dates.

Does the optional Writing section affect my composite score?

No, the ACT Writing section (where offered) is scored and reported separately and does not factor into the 1-36 composite score, which is based solely on the English, Math, Reading, and Science sections.
