GED and HiSET Modular Subtests
The HiSET, like the GED, assesses knowledge at a level that compares to that of high school graduates.
There are five independent HiSET subtests assessing a student’s level of knowledge in these academic areas:
- English Language Reading
- English Language Writing
- Mathematics
- Science
- Social Studies
GED testing includes four separate sub-exams since the reading and writing sections were merged into one Language Arts subtest.
HiSET testing can be done on a computer or on paper, whereas the GED is fully computer-based. You don’t need to take the entire GED or HiSET battery in one session. All modules can be taken if you wish, one at a time and in any order.

Your Future
In the U.S., there are millions of people who don’t have a high school diploma, and completing the HiSET or GED exam will give them a lot more employment possibilities and open doors to colleges and universities.
Annually, over half a million people pass the GED or HiSET test, and you could be one too. You may also use this website’s free GED video lessons and practice tests to get all set fast, also for the HiSET exam.
Both exams are offered in English and Spanish and are great instruments for you in your efforts to achieve your long-term goals in education and employment. Every test center offers accommodations for candidates with disabilities or health-related requirements.
When you pass the HiSET or GED exam, you have demonstrated that you have the academic knowledge and skills at a level comparable to those of graduating high schoolers.
The HiSET and GED exams are aligned with Common Core Standards, and with this website’s free practice tests and video lessons, you can get familiar with the exam formats, questions, and computer-based testing.
The Online HiSET and GED Test
In the past, you couldn’t take the HiSET or GED test online. But some years ago, we saw the launch of the ‘HiSET-at-Home’ and the Online Proctored (OP) GED exam.
When you decide to take the HiSET or GED exam at home, an online proctor will see if all goes according to some rather strict regulations.
To read more detailed information about the online HiSET exam, go to: Introducing the online HiSET exam.
To learn more about the Online Proctored GED Test, <- check here.
Please note that to qualify for online GED testing, you must first attain passing scores (in the ‘green’ range) on the GED Ready practice test from GED Testing Service.
Each GED sub-exam requires you to pass a GED Ready test, so that’s four overall, for a total of $32 ($7.99 per test) on top of the testing fees.
Free GED Ready Vouchers
If you use one of the My Advantage Plans by Onsego, you save $32! These plans already include four GED Ready vouchers at no cost, a fine $32 bonus!
