Student/family FARMs eligibility is confidential. HCPSS will only discuss student eligibility with students, parents, guardians and cafeteria managers. All HCPSS schools currently use a Point of Sale (POS) system in cafeterias. All students must enter a six digit (6) PIN number in the POS system to pay for meals. By using this system, students do not know if a classmate’s lunch was pre-paid, free or reduced price.
