What the GED is and who takes it

The GED is a test that shows you have high school-level knowledge, even if you didn't graduate from a traditional high school. When you pass it, you receive a GED credential — a document that employers and colleges recognize as equivalent to a high school diploma. You take the test through your state's education department, and the credential is issued by the state where you test.

People take the GED for different reasons. Some left high school before graduating and want to move forward with work or college. Others need the credential to enter a training program or military service. Some are adults returning to education after years away, and some are immigrants who completed schooling in another country and need a U.S. credential.

The test is offered year-round at testing centers — usually community colleges, adult education programs, libraries, or private testing sites. You don't have to attend a GED class to take the test, though many people do because the test covers a lot of ground.

Key Takeaways

  • The GED test has four sections — reasoning through language arts, social studies, science, and math — and you can take all four on one day or spread them across multiple test dates.
  • You must be at least 16 or 17 (depending on your state) and not currently enrolled in high school to take the test.
  • The test costs money to register, usually between $100 and $200 total depending on your state, though some programs cover the fee for low-income test-takers.
  • Most people study for several weeks or months before testing, either through free community programs, online courses, or on their own with study materials.
  • Passing scores are set by your state, not nationally, so you need to know your state's passing standard before you test.

The four sections of the GED test

Reasoning Through Language Arts tests reading comprehension, grammar, and writing. You read passages and answer questions about what they mean, identify grammar errors, and write a short essay in response to a prompt. This section lasts about 150 minutes total.

Social Studies covers history, civics, economics, and geography. Questions are based on passages, maps, charts, and historical documents. You don't need to memorize dates or facts — the test gives you the information and asks you to understand it and draw conclusions. This section is 70 minutes.

Science tests your ability to read scientific information and think through problems. You'll see passages about biology, chemistry, physics, and earth science, along with diagrams and data. Like social studies, you're not expected to memorize — you read and reason. This section is 90 minutes.

Math covers algebra, geometry, and data analysis. About half the questions let you use a calculator; the other half you cannot. You'll solve equations, interpret graphs, and work through word problems. This section is 115 minutes, split into two parts.

Who can take the GED and basic requirements

You must be at least 16 or 17 years old — the exact age depends on your state. You cannot be currently enrolled in a public or private high school. If you're under 18, some states require you to have been out of school for a certain amount of time (often 30 days) before you can test.

You need a valid photo ID to show up on test day. A driver's license, passport, state ID, or military ID all work. If you don't have one, contact your testing center ahead of time to ask what documents they'll accept.

There are no other academic prerequisites. You don't have to have completed any specific grade level or taken any particular classes. The test itself is what determines whether you know the material.

How to prepare and what study options exist

Many people study for four to six months before taking the test, though the time you need depends on how much schooling you've had and how much you remember. Some people study for a few weeks; others take a year.

Free or low-cost study options include adult education programs run by your local school district, community colleges, libraries, and nonprofit organizations. These programs often offer in-person classes, online courses, or both. You can search for programs near you through your state's education department website or by calling your local community college.

Paid options include online GED prep courses (ranging from $50 to $300), private tutoring, and study books you buy yourself. Many online platforms let you take practice tests to see which sections need the most work.

You can also study on your own using free resources. The official GED Testing Service website has sample questions and study guides. Khan Academy offers free video lessons on math and science topics covered on the test.

Test registration, cost, and scheduling

You register for the test through your state's official GED testing website or by contacting a testing center directly. The registration process takes about 15 minutes online. You'll choose which test date and location you want, and you'll pay the registration fee at that time.

The cost varies by state, typically between $100 and $200 for all four sections. Some states let you pay per section if you want to spread out your testing. A few states offer reduced fees for people with low income — ask your testing center or check your state's GED website.

Testing centers usually have multiple dates available each month. You can often schedule your test within a week or two of registering, though busy centers may have longer wait times. If you need to reschedule, most centers allow you to move your test date for a small fee or no fee at all.

What happens on test day and after you test

Arrive 15 minutes early with your photo ID and any other documents the testing center requested. You'll check in, have your ID verified, and be taken to a computer station. The test is computer-based, so you'll read questions on a screen and type your answers or click to select them.

You can take all four sections in one day (about 7.5 hours with breaks) or spread them across multiple days. Many people take one or two sections at a time to avoid fatigue. There's no rule about how long you have between sections — you can test again the next day or wait weeks.

Your scores are usually available within 24 hours of testing. You'll see them online through your state's GED portal or receive them by mail. Your state will tell you what score you needed to pass — this varies by state, so a passing score in one state might not be passing in another.

If you pass all four sections, your state will issue your GED credential. If you don't pass one or more sections, you can retake just those sections. Most states let you retake a section within a certain timeframe (often 30 days after your first attempt, or after waiting a set number of days).

Using your GED credential for work and education

Employers recognize the GED as equivalent to a high school diploma for hiring purposes. You can list it on job applications and resumes the same way you would a diploma. Some employers specifically ask for a high school diploma or GED, and your credential satisfies that requirement.

Colleges and universities accept the GED for admission. You can use it to explore to community colleges, four-year universities, or trade schools. Some schools may require additional testing (like the SAT or ACT) or may place you in developmental courses depending on your GED scores, but the credential itself opens the door to higher education.

The military accepts the GED for enlistment. If you're interested in military service, check with your branch's recruiting office about any additional requirements they may have.

Your GED credential is valid for life — there's no expiration date. Once you pass, you have the credential permanently.

Frequently Asked Questions

Can I take the GED if I'm still in high school?

No. You must not be enrolled in a public or private high school to take the GED. If you're in high school and want to leave, you'll need to formally withdraw or graduate first. Talk to your school counselor about your options.

What if I fail one section — do I have to retake all four?

No. You only retake the sections you didn't pass. If you pass three sections and fail math, you register to retake just the math test. Your passing scores stay on record.

How many times can I retake the test?

Most states let you retake sections as many times as you need, but there are limits on how often you can test in a short period. Many states require you to wait 7 to 30 days between attempts on the same section. Check your state's rules on their GED website.

Is the GED the same in every state?

The test itself is the same — all states use the same GED exam created by the GED Testing Service. However, passing scores vary by state. A score that passes in one state might not pass in another, so you need to know your specific state's passing standard.

Can I get my GED online?

You can study for the GED online, but you must take the actual test in person at an approved testing center. The test cannot be taken remotely.
