Truancy: the action of staying away from school without good reason; absenteeism. (Had to google it! Thanks for a new word)

Truancy can be dealt with by providing food to the kid at the end of the school day, food meant to be brought home.

There are of course arguments against this, e.g., school are not meant for this. Well, schools are not meant to operate with absent students and whatever can fix should be considered.
