Posted here are all GED preparatory classes and testing facilities in the Denver area. Colorado offers two options for high school equivalency testing: the HiSET and GED exams.
The GED and HiSET exams are available at certified test centers or online. Read more below.
The exams give adults who didn’t graduate high school another shot at earning an equivalent diploma.
Both tests are administered at a level comparable to that of graduating high school seniors.
Online GED Classes
A simple and easy way of getting your GED diploma.
You can prepare for the exams with a teacher at one of the locations listed on this page, but you can also benefit from a good online GED course, like the accredited program designed by Onsego Online GED Prep, a course that GED Testing Service qualifies as “fully GED test aligned.”

Online GED and HiSET Testing
Today, candidates wishing to earn their Colorado high school equivalency (HSE) diploma can do so online as well. In the past, to earn your GED diploma, you had to appear in an official Colorado test center and sit for the exam in person.
That has changed. Both GED and HiSET tests are now also offered in an online format while using an online proctor. You can read more about these interesting developments here: ‘The online GED test,’ and for the HiSET: ‘The online HiSET test.’
