Summary
Lakeridge combines a neighborhood K–5 program with Mercer Island's centralized Code 33 Highly Capable classrooms for identified students in grades 3–5. Its official profile centers belonging, empathy, responsibility and student agency, and its recent statewide results are nearly indistinguishable from Island Park's. The HC cohort can affect enrollment, peer mix and schoolwide test data, so families should compare the neighborhood kindergarten experience directly.
Enrollment, academics and programs
| Measure | Value | Source/year |
|---|---|---|
| Projected total enrollment | 391 FTE | MISD 2025–26 projection |
| Projected kindergarten enrollment | 42 FTE | MISD 2025–26 projection |

- MISD's Code 33 service places holistically identified students in unique classrooms at Lakeridge for grades 3–5. Code 32 service remains in the regular classroom, and Primary Enrichment Services serve qualifying grades 1–2 students.
- The school profile describes a schoolwide LION framework: lead with empathy, include everyone, own your learning, and notice and name your impact.
- District multilingual and special-education services are available; confirm K staffing, service schedules and how the HC site affects shared activities.
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. Code 33 placement is a separate district identification route, not ordinary neighborhood assignment.
Fit considerations
Possible strengths: exceptional recent results, explicit inclusion and student-agency framework, and the district's centralized grade 3–5 Code 33 HC pathway. Main concerns: the HC cohort complicates apples-to-apples score and enrollment comparisons; kindergarten class size and play remain unverified. Next action: tour K and ask how neighborhood and HC cohorts interact.
Questions for the school
- How many kindergarten sections are planned, and what are the expected class sizes?
- How much choice, free play, recess and outdoor time does a typical K day include?
- How do neighborhood and Code 33 students share specialists and community activities?
- What adult learning-support and paraeducator coverage is present in kindergarten?
- What before/after-school care is available, and is there a waitlist?
