Verify whether the 18 year old is a full-time student in high school or in an equivalent vocational/technical training program. In Cook County, the Chicago Board of Education (CBOE) Online system can be used to verify school status.
If the child meets the above school requirements, the child remains eligible. Be sure Item 73 is coded 5 for the child.
Enter a code B in Item 73 of Form 552 if the child is not attending high school full-time. The child remains eligible for the month in which age 18 is reached, but is ineligible for the month after. A child coded B in Item 73 is automatically changed
to medical only for the fiscal month following the calendar month in which age 18 is reached. If there is no other eligible child, the case is automatically placed in zero grant. Form 157C is sent by the system.
