In general, students must be at least 18 years old in order to enroll in adult education classes. However, 16 and 17 year-olds may register with an official release letter certifying that they are no longer attending high school. (Recent arrivals to Chicago age 16 and 17 must have a parent or guardian fill out a form verifying that they have never attended a Chicago-area public school.)
Adult Education classes are intended for people who live in or near Chicago. Students who hold J1 visas are not permitted to take Adult Education classes.
