High School Equivalency Test (HiSET®)

The specific purpose of the HiSET® exam is the measurement of the educational development of adults who have not completed their formal high school education. Adults may earn a High School Equivalency Certificate and thus qualify for admission to colleges or other educational institutions, meet educational requirements for employment or promotion, satisfy educational qualifications for induction into the armed services, fulfill requirements of local or state licensing boards, or gain personal satisfaction.


An individual is eligible to take the HiSET® exam given they meet all of the following conditions:

  • 18 years of age or older*
  • does not have a high school diploma or high school equivalency credential and is not currently enrolled in a secondary school
  • is a resident of the State of Illinois

Note: *If an individual is 17 years old and has been enrolled in a public, private, or a home school setting in the last 12 months, they must present a withdrawal letter from the last school enrolled in before taking the HiSET® exam. If homeschooled, they must also provide a letter from the person responsible for the homeschooling [e.g., instructor, tutor, parent, guardian, etc.] stating the program has been completed, the individual is no longer required to be homeschooled, and the individual has been cleared to take the HiSET® exam.  Proof of withdrawal can be emailed to ilhseiccb@iccb.state.il.us or faxed to 217-558-6700.



You can register online to take the HiSET® exam at hiset.ets.org. Although registration is done online, the tests will actually be administered in paper/pencil format or on a computer at an official HiSET® testing site that you select during registration.  Testing fees must be paid at the time of scheduling.
