ACT® · The Enhanced ACT: Format, Scoring, and the Clock
Testing With One and One-Half Time
Extended time multiplies each section's minutes by 1.5, giving more seconds per question. It does not change the questions, so the real shift is in pacing strategy, not difficulty.
One and one-half time is a clock adjustment, not a content adjustment. Every standard section length gets multiplied by 1.5. A 35 minute section becomes 52.5 minutes, a 50 minute section becomes 75 minutes, and two 40 minute sections each become 60 minutes. The questions, the answer choices, and the passages stay exactly the same. What changes is how much breathing room you have to work through them.
That extra room changes strategy more than it changes effort. On standard time, pacing is tight enough that many students move fast and skip hard questions to protect their average speed per question. On extended time, the per question budget grows, so the smarter move is often to slow down on reasoning heavy questions, reread tricky sentences, and double check answers before moving on, rather than just doing the same rushed approach slower. The skill being tested is unchanged. What shifts is how you spend seconds you now have more of.
This matters because the rest of the format, the number of questions, the order of sections, and how scores are built from raw counts of correct answers, stays identical. Extended time sits next to the standard clock as a parallel version of the same linear test: same sections, same content, same scoring logic, just stretched by half. Understanding this keeps you from treating extended time as a content advantage instead of a pacing adjustment.
Key terms
- One and one-half time
- An accommodation that multiplies every section's standard minutes by 1.5.
- Seconds per question
- A section's total time in seconds divided by its number of questions, used to measure pacing.
- Linear test
- A test where every student sees the same fixed set of questions in the same order, unlike an adaptive test.
- Section length
- The number of minutes officially assigned to complete one part of the test.
