State law governs the Schools of Choice process.  School districts have the option of participating in Schools of Choice on an annual basis.  Districts may advertise available slots and accept applications only at specific times.  Okemos Public Schools has been a participating district in the Schools of Choice process since its inception.  The Board of Education usually makes the decision about the district's participation in Schools of Choice in April or May.  At that time the number of slots and grade levels will be identified and published.
