What Is the Duration of a HiSET Test?

The duration of a HiSET test varies by subject, with each section timed separately. You do not need to complete all five subjects in one day. Most test takers schedule them individually over weeks or months. Here is the exact duration of a HiSET test per subject:

  • Language Arts – Reading: 65 minutes
  • Language Arts – Writing: 120 minutes (75 minutes for multiple choice, 45 minutes for the essay)
  • Mathematics: 90 minutes
  • Science: 80 minutes
  • Social Studies: 70 minutes

This makes the total testing time approximately 7 hours and 35 minutes if taken all at once. However, since you can take each subject on a different day, the daily burden is much lighter.

All tests are computer-based and administered at official testing centres or online (where available). You must arrive on time,late entry is not allowed.

Managing Your Testing Time

Understanding the duration of a HiSET test helps you build stamina and pacing. Each section includes only one question type per screen, so you can focus without distractions. There are no scheduled breaks within a subject, but you may pause briefly between sections when taking multiple exams in one day.

Use the full time wisely:

  • In Math, double-check calculations before submitting.
  • In Writing, spend 5–10 minutes planning your essay.
  • In Science and Social Studies, read passages carefully before answering.

Practice with full-length, timed tests from the official HiSET Practice Test at hiset.ets.org. This builds confidence and reduces test-day anxiety.

The duration of a HiSET test is fixed, so preparation should include time management. Aim to finish each section with 5–10 minutes to review. With consistent practice, the timing becomes predictable and manageable.

Your success depends not just on knowledge—but on using every minute well.
