LOS ANGELES (AP) — California school districts must have procedures in place by Friday for students and parents to file complaints if they feel their schools are improperly charging fees for educational activities.

The American Civil Liberties Union of Southern California said Wednesday that the deadline was established in Assembly bill 1575 that was signed into law by Gov. Jerry Brown last fall.

The ACLU sued the state in 2010 after finding many school districts require students to pay fees to participate in certain activities and purchase textbooks and other academic materials. The ACLU says such fees violate the state Constitution that guarantees a free public education to all children.

The ACLU agreed to dismiss the lawsuit after the bill mandating districts set up accountability systems was signed.
