Pass the GED/HiSET

Whether you’re an adult learner or a high school student looking to earn your high school diploma or a high school equivalency certificate, this page will provide practical guidance on what to expect, how to prepare, and how to get started.

What is the GED and HiSET?

The GED (General Educational Development) and HiSET (High School Equivalency Test) are two nationally recognized exams that allow adults to earn a credential equivalent to a high school diploma. Both are accepted by employers and colleges across the United States.

Neither test requires you to be enrolled in school. You study at your own pace and schedule the exam when you feel ready. However, an adult school can help you study for the test if you need help.

Both the GED and HiSET are accepted by employers and colleges across the United States. Both are offered in English and Spanish.

Test breakdown by subject

Both exams assess the same core academic areas. Here’s what each subject covers and roughly how long it takes.

  • Mathematical reasoning: Basic math, geometry, algebra, and data analysis. A calculator is allowed for most of the GED math test. ~115 min.
  • Reasoning through language arts: Reading comprehension and writing, including an extended response (essay). ~150 min with break.
  • Science: Life science, earth/space science, and physical science. Focuses on interpreting data and scientific reasoning. ~90 min.
  • Social studies: Civics, U.S. history, geography, and economics. Requires reading and interpreting charts, maps, and passages. ~70 min.

The HiSET separates language arts into two tests — reading and writing — making it a 5-test exam. Total test time across both exams is roughly 7–8 hours. You do not have to take all subjects on the same day.

Study tips and resources

Most people who pass spend several weeks to several months preparing, depending on how much time they can commit and how long ago they were in school. Consistent practice matters more than cramming.

  • Take a practice test first. Both GED and HiSET offer free official practice tests. Your results will show which subjects need the most attention so you can focus your study time.
  • Study consistently, not in bursts. Even 30–60 minutes a day, five days a week adds up quickly. Setting a regular schedule helps material stick better than occasional long sessions.
  • Use free official prep tools. GED.com offers a free prep platform called GED Ready. Khan Academy covers all tested subjects for free and works on any device.
  • Look into local adult education classes. Many community colleges, libraries, and workforce centers offer free or low-cost GED/HiSET prep classes with an instructor. These are especially helpful for math or writing.
  • Practice writing the essay. The extended response section trips up many test-takers. Practice writing a structured 4–5 paragraph argument using evidence from a passage — time yourself to stay under 45 minutes.
  • You can retake individual subjects. If you don’t pass one section, you only need to retake that subject — not the entire exam. Don’t let one subject delay you from scheduling the others.
