The ACT test without the optional writing section takes about 2 hours and 55 minutes (175 minutes) to complete. When including the optional writing section, the total test duration extends to about 3 hours and 35 minutes (215 minutes). Additionally, there is a 10-minute break between the Math and Reading sections and, if taking the writing test, a 5-minute break after the Science section, making the total time at the test center approximately 3 to 3.5 hours without writing and closer to 4 hours with writing.
Time Breakdown by Section
- English: 45 minutes (75 questions)
- Math: 60 minutes (60 questions)
- Reading: 35 minutes (40 questions)
- Science: 35 minutes (40 questions)
- Writing (optional): 40 minutes (1 essay)
- Breaks: 10-minute break after Math, and 5-minute break before Writing (if applicable)
The newer Enhanced ACT format from 2025 reduces the length somewhat, with the test lasting around 2 hours and 15 minutes excluding breaks and the optional science section becoming optional starting September 2025. However, the traditional format still generally applies and results in about 3 hours without writing and longer with writing. Overall, expect a total testing time of about 3 hours without writing and about 3 hours and 35 minutes with writing, plus additional time for breaks and administrative tasks on test day.
