Summary
Endeavour is a mid-sized Issaquah School District elementary school with strong recent assessment results, a substantial literacy-support structure and one of the district's two self-contained MERLIN highly capable programs for grades 3–5. The school entered 2026–27 with a new principal after an interim leadership change during 2025–26, so leadership stability and current school climate deserve direct follow-up before a prospective student's entry year.
Enrollment and staffing
| Measure | Value | School year/source |
|---|---|---|
| Total enrollment | 473 | 2024–25 NCES |
| Kindergarten enrollment | 55 | 2024–25 NCES |
| Classroom teachers (FTE) | 30.10 | 2024–25 NCES |
| Student/teacher ratio | 15.71:1 | 2024–25 NCES |
Interpretation
Endeavour was larger than Cascade Ridge by 82 students in 2024–25, while its schoolwide student/teacher ratio was slightly lower. Neither figure identifies kindergarten class size: specialists, MERLIN teachers and other teaching assignments affect the ratio.
Academics
| Measure | Result | School year |
|---|---|---|
| ELA meeting or exceeding standard, grades 3–5 | 88.4% | 2024–25 |
| Math meeting or exceeding standard, grades 3–5 | 88.7% | 2024–25 |
| Grade 5 science meeting or exceeding standard | 89.0% | 2024–25 |
These percentages were calculated from OSPI's reported Level 3 and Level 4 results for all students. State assessments begin after kindergarten and are influenced by student population and participation. They are one indicator, not a direct evaluation of a prospective student's future teacher or classroom.
The Washington State Board of Education recognized Endeavour for 2024–25, citing growth for students in one or more racial or ethnic groups and achievement in ELA, math and attendance.
Kindergarten experience
- Issaquah School District offers tuition-free full-day kindergarten.
- For 2026–27, the district also offered a three-hour morning kindergarten option; this must be reconfirmed for 2027–28.
- Endeavour held an incoming-kindergarten information night on January 28, 2026, before district registration opened.
- The district uses WaKIDS teacher/family connection and whole-child observation at the start of kindergarten.
- Typical class size, daily play and recess time, and dedicated paraeducator support remain to be confirmed directly.
Culture and community
Verified information
- The school mission emphasizes an inclusive community in which students become kind, lifelong learners.
- Schoolwide expectations are to be respectful, responsible, safe and a learner.
- The 2024–26 improvement plan emphasized foundational literacy, inclusionary practices, Universal Design for Learning and tiered academic and behavioral support.
- PTSA-supported activities included Read Across Endeavour, a STEAM fair, an art walk, Jaguar Jumpstart for incoming kindergarten families and up to four art lessons per class.
- School clubs and activities recently included arts and crafts, chess, choir, coding/robotics, drama and safety patrol.
Leadership context
- Gary Aguilar became interim principal on December 8, 2025.
- Jennifer Sehlin, formerly the Cascade Ridge principal, became Endeavour's principal for 2026–27.
- Because 2025–26 included a midyear change followed by another transition, ask about staff retention, school climate and whether leadership systems have stabilized.
Visit observations
- No firsthand visit or observation recorded yet.
Programs and student support
- Endeavour hosts one of two district MERLIN sites, with a self-contained, full-day highly capable class in each of grades 3, 4 and 5. Qualification and site placement are district-controlled; families provide transportation.
- SAGE reading and math enrichment is available to identified highly capable students who are not in MERLIN.
- The school reports a Learning Resource Center, multilingual-learner support and a Learning Assistance Program focused on foundational reading skills for younger students.
- Its literacy-success blocks use assessment data, small-group instruction and Really Great Reading supports.
- Library, music and physical education are part of the district elementary program; school-specific frequency should be confirmed.
- The districtwide MTSS framework provides tiered academic, social-emotional, behavioral and attendance support.

Logistics
- Distance from home: To be calculated.
- Typical travel time: To be tested during morning arrival hours.
- Walking/biking feasibility: Unknown; the campus fronts SE Issaquah-Fall City Road, so the exact neighborhood route matters.
- Bus eligibility and route: Address-specific and must be confirmed for 2027–28.
- Before/after-school care: On-site district program called Jaguar Club; registration is waitlist-based.
- District care hours currently begin at 6:30 a.m. and run after dismissal until 6:30 p.m.
- Wednesday dismissal is earlier than other weekdays; reconfirm the 2027–28 schedule.
Enrollment and timing
Issaquah School District generally requires kindergarten students to be five by August 31 of the entry year. Confirm the current cutoff and registration rules with the district before applying.
Attendance is determined by the home address. A transfer would depend on space, staffing and district approval. Endeavour's current “Limited” status is for 2026–27 and cannot predict availability for a prospective student's entry year.
Fit considerations
Possible strengths
- Strong recent results across ELA, math and science, plus 2024–25 state recognition.
- Extensive literacy intervention and differentiated-learning systems.
- Active PTSA enrichment, including art, STEAM and incoming-kindergarten programming.
- MERLIN is available on campus in later elementary grades if a prospective student eventually qualifies and is assigned there.
- Smaller recent kindergarten cohort than Grand Ridge.
Possible concerns
- Leadership changed during 2025–26 and again for 2026–27; current stability needs verification.
- Larger and potentially busier than Cascade Ridge.
- The roadside location may make walking or biking impractical depending on the home address.
- MERLIN enrollment adds older students from beyond the neighborhood and does not itself benefit kindergarten students.
- Before/after-school care is waitlisted.
Information needed before deciding
- Whether the home address is within the Endeavour attendance boundary.
- Expected 2027–28 kindergarten class count and size.
- Staff retention, current school climate and stability of the new leadership team.
- Stability and experience of the kindergarten teaching team.
- A prospective student's reaction to the campus during a visit.
- Actual commute, bus and Jaguar Club availability.

Decision notes
- Current status: Researching
- Overall assessment: Strong academic option, pending a closer look at leadership stability and daily kindergarten experience

- Next action: Confirm assigned school, then attend the 2027 incoming-kindergarten event and ask about leadership and staff stability
