For Illinois schools

Illinois schools: test under SOS, file theory online.

Illinois puts its weight on the skills test, not the classroom: the Secretary of State licenses private schools, municipalities and agencies to give the skills exam, and layers a state School Bus Permit on top of the S endorsement. Theory can come from anywhere on the registry.

The short version: if you are an SOS-certified third-party tester, you keep that. Theory can be ELDT365 at $20 per student, filed the moment they pass, with your dashboard showing who is ready to test. Under 49 CFR 380.703(i) Illinois cannot require online theory to come from a state-licensed school. English-only written tests and the escalating retest waits make finishing theory early worth it.

What is particular to Illinois

SOS Third-Party Certification Program

Private companies, municipalities, fire departments and agencies licensed to give the Class A, B, C and M skills tests under 625 ILCS 5/6-508.

State School Bus Permit

A separate Illinois permit on top of the CDL S endorsement for anyone driving Illinois schoolchildren, with fingerprinting, an annual physical, and an annual refresher.

English-only written tests

All SOS written tests are in English. Students who train in Spanish need to be ready to test in English.

Escalating retest waits

30 days after three knowledge-test failures, 90 after six, a year after nine. Solid theory before the first attempt matters.

Questions schools ask

Does Illinois require the theory provider to be licensed by the state?

No. The SOS program licenses skills testers and BTW schools; online theory is governed by 49 CFR 380.703(i) and the registry.

Can a third-party tester also be a BTW provider?

Yes, many are. Both are separate from theory.

Do you cover the Illinois School Bus Permit?

No. That is a state permit administered separately from the CDL, with its own physical and fingerprinting. We offer School Bus endorsement theory for the S; the state permit is on top of it.
