Frequently asked questions
Where do section scale scores come from?
ACT converts raw scores (questions right) to the 1–36 scale using a form-specific key. Practice tests include their key; this calculator starts from the scale scores those keys produce.
Does the writing score affect the composite?
No. The optional writing test is reported separately (and in an ELA average with English and Reading at some schools), but the headline composite uses only the four sections here.
What is the national average ACT score?
Recent graduating classes have averaged around 19–20 composite. Averages at selective colleges run far higher — check each school’s published ranges.
