How testing works
GED testing: how the test actually works
GED testing is computer-based, split into four separate subject exams you take when you're ready — at an official centre or online with a proctor. Here's the whole process, from format to test day to results.
What GED testing involves
GED testing isn't a single sitting. The GED is made up of four subjects — Mathematical Reasoning, Reasoning Through Language Arts, Science and Social Studies — each a separate, computer-based exam. You don't sit them all in one day; you take them one at a time, when you're ready for each. Full detail of what's in each is on the GED subjects page.
Computer-based format
Every subject is answered on a computer using a mix of question styles — multiple-choice alongside drag-and-drop, fill-in-the-blank, hot-spot and drop-down items, plus a written essay in RLA. There's no paper version. For the official, current content outlines, GED Testing Service publishes them at ged.com.
Where you test: centre or online proctoring
You can sit the test at an official GED test centre, or online with a remote proctor supervising. You choose when you book — the full booking process is on the scheduling guide, and the conduct rules that apply during testing are on the exam rules & security page.
On test day
Arrive (or log in) ready, with valid ID and any permitted tools — for maths and some subjects an on-screen calculator is provided, and you may bring your own TI-30XS. Follow the invigilator or proctor's instructions closely.
After testing: your results
Each subject is scored against a scale where 145 is the pass mark. Reach 145 on all four and you've earned the GED. Higher bands (College Ready, College Ready + Credit) carry extra benefits abroad — see GED test scores explained.
Frequently asked questions
Yes. All four GED subjects are computer-based, taken at an authorised testing centre or online with a remote proctor. There's no paper version.
