Summary
West Mercer is the largest of the four schools in the district's 2025–26 projection. Its profile documents multilingual, special-education and enrichment services, a strong PTA, positive-behavior supports and a notably broad set of student leadership and community activities. The school remains a top-ranked statewide option, while its larger kindergarten projection makes section count and class size especially important to verify.

Enrollment and timing
Kindergarten students must turn five by August 31 of the entry year. Families register at the home school determined by the district boundary map and provide two proofs of residency, age documentation and immunization records. For 2026–27, registration opened January 29, 2026 and all four elementary schools were closed to new nonresident enrollment. Recheck dates and capacity annually.
Fit considerations
Possible strengths: excellent recent results, broad leadership and arts activities, explicit math-growth and student-goal systems, and extensive family community events. Main concerns: largest projected school and K cohort in the district; actual section count, class size, traffic and care capacity need confirmation. Next action: tour K and verify the operational details.
Questions for the school
- How many kindergarten sections serve the projected cohort, and what are class sizes?
- How much choice, free play, recess and outdoor time does a typical K day include?
- Which clubs and leadership activities are available to primary-grade students?
- How does the math-growth plan change daily kindergarten instruction?
- What before/after-school care is available, and is there a waitlist?
