Option schools provide a variety of programmatic opportunities, different curriculum, and educational styles for families looking for alternatives to their attendance area school. Assignment is by application only, based on set tiebreakers, and seat availability. (For language immersion schools, student eligibility is determined by a language proficiency exam.) Option schools are designed to relieve capacity at nearby attendance area schools. The application period for option schools begins in late winter (typically February) during Open Enrollment and continues through May 31. Students new to the district after May 31, may enroll in their attendance area (or designated) school or an option school where space is available.
