Parent Portal

Platte County R-3's student and parent information system (SISK12 Parent Portal) allows parents and students access to important, up-to-date student information. With effective parent communication and involvement, we can help drive student success. Parent Portal allows parents access to class schedules, attendance, homework, grades, discipline, and lunch balances.
