Curious about how long the HiSET takes to complete in the US (and available in Kenya via approved centers)? The HiSET exam consists of 5 separate subtests with a total testing time of 7 hours and 5 minutes—but you don’t take it all at once. This guide breaks down the duration of the HiSET by section, format, and scheduling tips.
Total HiSET Exam Time: 7 Hours 5 Minutes
The HiSET takes 425 minutes across five modules:
- Language Arts – Reading: 65 minutes
- Language Arts – Writing: 120 minutes (includes essay)
- Mathematics: 90 minutes
- Science: 80 minutes
- Social Studies: 70 minutes
Total: 7 hours 5 minutes of actual testing.
Can You Take the HiSET in One Day?
No—most test centers split it over 1–3 days to avoid fatigue.
- Option 1: 2 days (e.g., Reading/Writing Day 1; Math/Science/Social Studies Day 2)
- Option 2: 5 separate appointments (one per subtest)
You control the schedule—retake only failed subtests.
