The Sumner School District has established boundaries for each high school, and students are expected to attend the designated high school based on the location of their residence and the boundary lines. The School District does not have an open enrollment policy. Students wishing to attend a school other than his or her resident high school, must apply for a waiver through the Sumner School District Waiver office. This applies to 8th grade students selecting a non-resident high school for his or her 9th grade year.
Sumner School District students entering 9th grade are eligible for any level of competition at the high school he or she attends by meeting the following requirements:
