Set by GED Testing Service and the IllinoisDepartment of Education. Verify on official sources before your test date — rules change.
Illinois requires GED test takers to be at least 18. The rule applies to in-person and online testing alike. If you are 16 or 17, your path is a regular high school program or an adult-ed route through your district, not the GED yet.
Applicants cannot already hold a U.S. high school diploma and cannot be currently enrolled in an Illinois high school at the time of testing.
You must be an Illinois resident at the time of testing to receive an Illinois High School Equivalency Certificate. Out-of-state testers can sit the test here, but the diploma is issued by their state of residence.
A current Illinois driver's license, Illinois state ID, U.S. military ID, or passport is accepted at every Illinois testing center. Expired IDs and school IDs are not accepted.
Both options are available statewide. Online proctored testing requires a recent 'green' score on a GED Ready practice test, plus a webcam and a private quiet room.
You must score at least 145 on each of the four subject tests independently. Subjects can be retaken one at a time without re-doing the others.
Illinois has no standard under-18 testing path. Younger learners finish a high school program or an adult-ed route.
These are the official fees from GED Testing Service for Illinois test takers — what the test itself costs. Our prep is a separate one-time payment, with a Pass Guarantee on the Pro plan.
Charged at the testing center or online checkout.

In Illinois, free adult-education GED prep is state-funded, and for some learners that is a genuinely good fit. Here is an honest look at where it works — and where self-paced online prep works better.

Real Illinois students. Real diplomas. Real next chapters — nursing programs, college, the National Guard, the promotions they were capped on.
Started a Medical Assistant program at City Colleges of Chicago.
“I work the early shift, so I studied before the kids woke up. Eleven weeks, forty minutes a morning. The reading section clicked once I stopped panicking and started reading the questions first.”
Enrolled at Rock Valley College for a welding certificate.
“I failed math the first time by a few points. The retake was cheap and I only had to redo that one subject. Passed it the second time and started classes that fall.”
Promoted to team lead at a distribution center.
“I tested in Spanish because that is how I think through math. Same diploma. My supervisor moved me to lead the week after I showed him the certificate.”
Joined the Illinois Army National Guard.
“The recruiter said no diploma, no contract. I studied two months on my phone during breaks. Scored above the cutoff on every section and signed the next month.”
Same four steps for everyone. Most students reach the final step in eight to fourteen weeks.
A 45-minute baseline across all four subjects produces a personal heat-map of what to study first. The plan is built from your data, not a template.
Short video lessons, then practice on the same skill the same day. The platform reorders your queue around what you miss.
Full-length, timed simulations that look and feel exactly like the official test. Three clean passes and you are ready.

Schedule the official GED through ged.com (run by GED Testing Service) at any of the 40+ testing centers across Illinois, including the City Colleges of Chicago, or take it online from home with proctoring.

Yes. The Illinois High School Equivalency Certificate is treated identically to an Illinois high-school diploma by every accredited college, every employer, and every branch of the U.S. military. It is issued by the Illinois Community College Board after you pass all four sections.
The official test is $36 per subject, or $144 for the full four-subject battery — the same price in person and online. If you fail a subject, the discounted test-center retake costs only the test-center fee (about $10) because GED Testing Service waives its $26 fee; online retakes stay $36. GED prep classes are free through Illinois community colleges, and our prep is a separate one-time payment.
No. Illinois requires GED test takers to be 18 or older. If you are 16 or 17, your options are to wait until 18, finish a regular Illinois high school program, or work with your district on an adult-ed pathway. Some other states allow 16- or 17-year-olds to test under conditions; Illinois does not.
Yes. Online proctored testing is available statewide through GED Testing Service. You need a recent 'green' (likely-to-pass) score on a GED Ready practice test, a webcam-equipped computer, and a private quiet room. The price is the same as in person — $36 per subject.
Most students who study consistently for 45 to 60 minutes a day are test-ready within 8 to 14 weeks. Your day-one diagnostic shows where you actually stand, and the plan adapts from there. Illinois does not require a minimum number of prep hours.
Yes. To receive the Illinois High School Equivalency Certificate you must be an Illinois resident at the time of testing. Out-of-state testers can still sit the test in Illinois, but the diploma is issued by their state of residence, not Illinois.
Yes. The GED test in Illinois is offered in English or Spanish, in person and online — you choose at registration. Twigera's prep is in English; we recommend testing in whichever language you read and think in most comfortably. The diploma issued is identical regardless of which language you test in.
