TRENTON - (AP) - Gov. Chris Christie has signed a lawallowing public school districts to bill parents for children'ssummer school classes.

The measure allows schools to pass on the costs of summerremedial and enrichment classes to families that can afford it.

Full tuition would be charged for students from families whosehousehold income exceeds the limit qualifying them for thereduced-price school lunch program. Less well-off families would becharged partial tuition.

Districts would be barred from charging families with incomesbelow the federal poverty guideline. A family of four earning lessthan $22,050 is considered below the poverty level.
