The Enhanced ACT Explained: What Changed and What It Means for You

Last updated:

The enhanced ACT is shorter, with fewer questions and more time per question. Science is now optional, the composite score is the average of English, Math and Reading only, and Math questions have four answer choices instead of five. The score scale is still 1 to 36, and scores from before the change remain valid.

What the changes mean for students

  • More time per question: every core section now gives more time per question than before, which helps students who felt rushed on the old ACT.
  • Science is your choice: skip it unless a college on your list requires or recommends it, or you are applying to STEM programs.
  • A STEM score: students who take Science also receive a STEM score, combining Math and Science.
  • Easier guessing odds in Math: with four answer choices instead of five, an educated guess is more likely to be right.
  • Shorter passages: English and Reading passages are shorter, so reading stamina matters a little less.

Is the enhanced ACT easier?

The content is similar, but the test is less rushed and shorter, which many students find more comfortable. Because scores are scaled, a given composite reflects the same level of performance as before, so colleges compare old and new scores directly.
