GED Classes Vacaville, California

Last Updated on May 1, 2024.

This article posts all GED preparatory class sites and testing facilities in the Vacaville region. California offers two options to adults wishing to earn their high school equivalency (HSE) credentials: the GED and HiSET exams.

Testing can be done online or at one of California’s official test centers. You can read more about online GED and HiSET testing below.

The exams are for people who have left high school before graduating and offer them the chance to earn an equivalent degree.

The fully computer-based GED exam includes four subtests (independent modules) that assess a student’s knowledge level in

  • Math
  • Science
  • Social Studies
  • Language

These GED modules are independent tests that may be taken separately and in any desired order.

The HiSET exam has five subtests (separate writing and reading tests) that can be taken separately as well.

Online Proctored GED and HiSET Tests

If you’re looking to earn your California high school equivalency degree, you can take the GED and HiSET exams online as well. Until recently, that option was not available. If you wanted to secure your GED, you were required to come in person to one of California’s state-approved test centers.

That has now changed! Both the GED and HiSET exams offer options to sit for the exams at home with the help of an online proctor. To learn more, check out the following articles: ‘The online proctored GED test’ and ‘The online proctored HiSET exam.’

For Who is the GED Test?

The GED (General Education Development) exam, just like the HiSET, is specially developed for adults who never completed high school and is meant to give them another chance to obtain an equivalent credential.

After passing the GED or HiSET exam, you will be awarded the California HSE diploma, which is all over the country recognized and accepted just like a regular high school diploma by government agencies, recruiters, businesses, and colleges and universities.


The HSE program is for persons who never finished high school and gives them one more chance to get a diploma that is, across North America, seen as the equivalent of a regular high school degree.

Both tests (GED and HiSET) will result, upon successful completion, in the California High School Equivalency Diploma, a credential that is your ticket to higher education and better job options.

The HiSET is used in the same way as the GED but is available in a computer- and paper-based format and contains five subtests (the Language portion is split up into separate writing and reading tests).

Passing Scores

GED scores are calibrated on a scale running from 100 to 200. On each GED subtest, you must attain at least a 145 score; that’s the GED passing score. On the GED, there are three passing score ranges:

  • High School Equivalency: 145-164
  • College-Ready: 165-174
  • College-Ready + Credit: 175-200

Your HiSET scores are calibrated on a scale running from 0 to 20. On each of the five HiSET subtests, you’ll have to reach a score of no less than 8. That’s the HiSET passing score. Your total HiSET score must be in the 45-100 range, and your essay score has to be at least 2 out of 6.
