Raw scores are modest, but students tend to gain ground relative to peers while enrolled.
Data confidence:High210 students tested 7 years97% participation
Confidence is computed from sample size, year coverage, and participation rate. Higher confidence means the rank shift is stable across years and not driven by a single small cohort.
- Tested students: total students with valid scores across all reported years.
- Years of data: number of school years included. More years smooths year-to-year noise.
- Participation: share of enrolled students who took the assessment. Low participation can bias scores.

Show the numbersFor the methodology-curious
Each component is converted to a 0–100 within-metro percentile (100 = top of the metro). "Contribution" is the percentile-points the component adds to (or subtracts from) the metro median before the schools are re-ranked into the composite.
| Component | Weight | Percentile | Contribution |
|---|---|---|---|
| Performs above what its context predicts | 35% | 64 | +4.8 |
| Students gain ground year over year | 30% | 91 | +12.3 |
| Equity within the school | 15% | 91 | +6.1 |
| Direction over recent years | 10% | 0 | -5.0 |
| Most students were tested | 10% | 97 | +4.7 |
Note: this school's Alpha-only Decoded Rank is #5 (vs the composite #2). The composite includes cohort progression and other signals that diverge from the context-adjusted Alpha. See methodology.
Why trust this?- Public data sources
- Context-adjusted model
- Confidence shown
- Methodology published
This score uses state assessment data, NCES enrollment data, and Census ACS 5-year neighborhood data. The Decoded Rank adjusts for school context — student demographics, ELL/SPED service rates, and the socioeconomic profile of the surrounding tract — and shows how the school performs relative to expectation, not in absolute terms.
SchoolDecoder is one signal, not a verdict. Decoded Rank is a context-adjusted residual, not a causal claim about teaching quality. See full methodology →

Performance Spread
How students are distributed across the four state-assessment proficiency levels — L1: below standard, L2: approaching, L3: meets (proficient), L4: exceeds. This describes the shape of results at the school, not their height.
Students at this school cluster closely on the proficiency ladder.
- Level 1 — Below standard22%
- Level 2 — Approaching standard30%
- Level 3 — Meets standard (proficient)33%
- Level 4 — Exceeds standard15%
Performance Spread measures how evenly students are distributed across the L1..L4 proficiency ladder, treating the levels as an ordered scale (L1=1, L2=2, L3=3, L4=4) and weighting each by its student share. A school where most students cluster at one level has a TIGHT spread; a school split between the bottom and top has a WIDE or BIMODAL spread. Bimodal fires only when BOTH tails are non-trivial AND the middle is relatively hollow (pct_L1 ≥ 15, pct_L4 ≥ 25, pct_L2 + pct_L3 ≤ 60). It describes shape — NOT how high the school's scores are.

Trajectory
Trending down
Based on 2 years (2023–2024).
Slope: -13.3 pct/yr (no CI — too few years)
Low confidence
How this works: we fit a linear trend across the available years of Decoded percentile, then bucket the slope into a direction. Wide confidence intervals (uncertain trends) collapse to Holding steady. See the methodology page for thresholds.
Cohort Progression
Kids who started 5th grade here in 2023 gained 62 proficiency points by 6th grade — gaining at about the metro median rate.
Cohort-to-cohort variance is high — interpret the headline cautiously.
Learning rate: +2.9 proficiency points/yr (95% CI -19.1 to 25.0)

How this works: we follow each grade-cohort across years through the school (3rd graders in 2023 are 4th graders in 2024, etc.) and fit a linear slope on a 100–400 proficiency-points scale built from the state assessment's four levels (L1=1, L2=2, L3=3, L4=4, weighted by student share). This is the same construction Stanford SEDA uses (edopportunity.org/methods); it's not student-level tracking — we measure the school's cohort, not individuals. See the methodology page for thresholds.
Student Growth (Washington)
Student growth percentile: the typical student here grew faster than 52% of Washington students with similar score histories.
Median Student Growth Percentile (SGP), as published by Washington's Office of Superintendent of Public Instruction. 50 is exactly typical for the state. Based on 8 years of data.
| Year | Math SGP | ELA SGP | Students |
|---|---|---|---|
| 2015 | 45 | 27 | 237 |
| 2016 | 42 | 30 | 252 |
| 2017 | 50 | 49 | 254 |
| 2018 | 55 | 39 | 261 |
| 2019 | 52 | 56 | 247 |
| 2023 | 65 | 50 | 189 |
| 2024 | 53 | 61 | 188 |
| 2025 | 61 | 43 | 192 |
Washington did not administer statewide tests during 2020–2022, so those years are absent — a gap in the data, not a score of zero.
How this works: a Student Growth Percentile compares a student's score change to other Washington students who started at a similar place, so it measures growth independent of where a student began. We show Washington's published medians; Oregon does not publish student growth percentiles, so this panel never appears on Oregon schools. See the methodology page for how growth enters the Decoded Rank.

What "Decoded Rank" means
Decoded Rank converts School Alpha — the context-adjusted residual — into a parent-facing rank within the metro pool. A higher Decoded Rank than Achievement Rank means the school's raw scores understate its performance once neighborhood and school context are held constant. The reverse means raw scores overstate it. The rank is one signal, not a verdict.
