To satisfy any community service requirement, the court may give preference to work which benefits the school said child attends. Said penalty shall be an administrative penalty and shall not be recorded on the custodial parent's or guardian's criminal record. The fine shall be payable to the court clerk to be deposited in the court fund. Nothing in this section shall prohibit the filing or prosecution of any criminal charge.
