In this article, we have listed all GED prep facilities and testing locations in the Fairfield area. California uses the entirely computer-based GED test for its High School Equivalency (HSE) testing program.
Additionally, the state offers the HiSET exam for this purpose. The HSE program is for adult learners without a high school diploma and provides another chance to earn an equivalent degree.
The GED and HiSET exams may be taken online or at one of California’s state-approved testing facilities. Read more below.
The GED is fully computerized, whereas the HiSET exam is offered in paper-based and computerized formats. Both HSE exams measure knowledge at a level that students must command after four years in high school.

Online GED and HiSET Exams
The HiSET and GED tests can now be taken online as well. It used to be that if you wanted to earn your HSE (High School Equivalency) credential, you had to appear in person at a state-approved test center. Now, that has changed.
To read all about the online “HiSET-At-Home” option, check this post: Online HiSET Test. To learn more about the online proctored GED exam, go to this article: The Online Proctored GED Test.
The GED Exam
The GED (General Educational Development) exam is a series of four independent tests that measure the academic skills, knowledge, and development of adults who did not complete their high school training. The GED credential is accepted as the equivalency of a high school diploma, which is necessary for most employment options.
The GED credential also satisfies entrance requirements for community colleges, vocational schools, and universities. The HiSET exam comes with separate reading and writing tests (so five in total) and serves the same purpose. You may very well benefit from the totally free practice tests for your GED HiSET exam that are offered on this website.
GED Testing Eligibility Criteria
To be eligible to take the California High School Equivalency exam, an applicant needs to be a California resident, but members of the armed forces stationed in California also qualify.
Candidates must be at least 18 years old and not be engaged in another school program. Those who are 17 must have been out of school for no less than 60 days and provide a request letter indicating the need to sit for the exam from the military, from a college or university, or from an employer.
If you are 17 and pass the HSE exam, you will not receive your equivalency diploma until your 18th birthday. For the remaining period, you will receive a letter of intent stating that your certificate is held until your 18th birthday.
HiSET and GED Passing Scores
The HiSET exam includes five tests (the literacy section is divided into writing and reading parts), is slightly cheaper than the GED exam, and is available in paper and computer versions, while the GED exam is only offered on computer. The passing score on each GED subtest is 145 (measured on a 100-200 scale), so you must attain at least 580 points overall.
- 145-164: High School Equivalent Passing Score
- 165-174: College-Ready Passing Score
- 175-200: College-Ready PLUS Credit Passing Score
The HiSET has a scoring scale of 20 points on each test, and the minimum required score is 8; your essay score must be at least 2 (out of 6), and your overall score needs to be at least 45, not including your essay.
