Summary
Island Park is the smallest of Mercer Island's four elementary schools in the district's 2025–26 projection and the highest ranked in the current SchoolDigger comparison. Its official profile emphasizes whole-child development, relationships, inclusive community and weekly music, PE, art and library. Address eligibility, the actual kindergarten section plan and daily classroom experience matter more than the small rank difference from Lakeridge.
Enrollment, academics and programs
| Measure | Value | Source/year |
|---|---|---|
| Projected total enrollment | 346 FTE | MISD 2025–26 projection |

- Weekly specialists listed in the school profile: music, physical education, art and library; classroom technology is described as a learning tool.
- MISD provides Primary Enrichment Services in grades 1–2 within the regular classroom. Grade 3–5 students identified for Code 32 receive in-class service; the self-contained Code 33 service is at Lakeridge.
- District multilingual and special-education services are available, but a prospective family should ask how staffing and service delivery work in K.
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 for the entry year rather than assuming this status will carry forward.
Fit considerations
Possible strengths: small projected enrollment, exceptionally strong recent grade 3–5 results, full specialist rotation and an explicit whole-child focus. Main concerns: schoolwide test results do not describe kindergarten play, class size or warmth; identified Code 33 students later move to Lakeridge. Next action: verify address assignment and tour a kindergarten classroom.
