State law requires fees for participation, but provides for waivers or a cap on the amount of money to be collected.
Oregon Revised Statutes 339.147 When tuition authorized; waiver of tuition and fees
(1)(a) Notwithstanding ORS 339.141, no district school board or public charter school as defined in ORS 338.005 shall require tuition for courses not part of the regular school program, except for traffic safety education, from a pupil who is a member of a low-income family in an amount in excess of what the low-income family may receive as money specifically to be used for payment of such tuition. (b) As used in this subsection, “low-income family” means a family whose children qualify for free or reduced price school meals under a federal program, including but not limited to the National School Lunch Act and the Child Nutrition Act of 1966, and all their subsequent amendments. (2) A family that does not qualify under subsection (1) of this section but believes the payment of school tuition is a severe hardship may request the district school board or public charter school to waive in whole or in part the payment of such tuition. (3) Any parent or guardian who believes that payment of any fee authorized under ORS 339.155 is a severe hardship may request the district school board or public charter school to waive payment of the fee and the board or public charter school shall waive in whole or in part the fee upon a finding of hardship. Consideration shall be given to any funds specifically available to the parent, guardian or child for the payment of fees or other school expenses. (4) No district school board or public charter school shall impose or collect fees authorized under ORS 339.155 from any student who is a ward of a juvenile court or of the Oregon Youth Authority or the Department of Human Services unless funds are available therefor in the court’s, authority’s or department’s budget. (5) No district school board or public charter school is required to waive any fee imposed under ORS 339.155 (5)(a) or (d).
