342.When do benefits end for a child who is attending elementary or secondary school?
If a child is attending elementary or secondary school full time when he or she turns 19 and has not completed the requirements for a secondary school diploma or equivalent certificate, the child's benefits continue through whichever of the following occurs first:
The month he or she completes the course;
The second month after the month the child reaches age 19 (if the school operates on a yearly basis, which is the usual case); or
The last month of the quarter or semester that is in progress when he or she reaches age 19 (if the school operates on a quarterly or semester basis and requires students to reenroll for each new quarter or semester).
