Typical Profile
Raw scores are low, and the school still trails similar schools even after accounting for context.
Low data confidence — interpret these rankings carefully. Small samples or low participation reduce how strongly the data supports the result.
Data confidence:Low37 students tested 4 years88% 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.
What's driving this rank
Decoded Rank: #1351 of 1506
in Washington schools
Raw test scores rank this school #1324, but families here have higher-than-average income and educational attainment, so the expected score is also high. After accounting for context, this school performs about as predicted — the Decoded Rank is #1351.

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 | 39% | 6 | -17.3 |
| Students gain ground year over year | 33% | 6 | -14.5 |
| Equity within the school | 17% | 97 | +7.9 |
| Most students were tested | 11% | 88 | +4.2 |
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 →

Middle of the pool
This is context-adjusted achievement (Alpha) — how grade 10–11 scores compare to expectations from the school's demographics. It is not the growth-based composite shown for elementary and middle schools, because a single-tested-grade high school has no consecutive-grade cohort to measure growth from.

Data limitations
- Graduation uses state cohort data. Coursework, offerings, and SAT/ACT counts use the latest available federal CRDC extracts, which can lag current graduation data.
- SAT/ACT data is count-only in this extract; without an enrollment denominator, we do not treat it as a participation rate.
- HS Decoded Rank is alpha-only: it summarizes how the school's grade 10/11 test scores compare to expectations from its demographic context, ranked against other HSs in the same metro / state / rural cohort. Graduation, AP, and SAT/ACT data above are descriptive context — they are not yet blended into the composite rank. The achievement-vs-decoded quadrant below plots context-adjusted ACHIEVEMENT (alpha) against raw achievement; it is NOT the growth-based composite shown for elementary and middle schools, because a single-tested-grade high school has no consecutive-grade cohort ladder from which to build a growth signal.

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 standard43%
- Level 2 — Approaching standard30%
- Level 3 — Meets standard (proficient)23%
- Level 4 — Exceeds standard4%
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
Not used in the Decoded Rank — shown for context only.
Not enough years yet
Trajectory will appear once we have two or more years of rankings for this school.
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 8th grade here in 2023 gained 41 proficiency points by 10th grade — gaining about 6× the metro median rate.
Based on 2 cohorts across math + ELA.
Learning rate: +14.7 proficiency points/yr (95% CI -6.2 to 35.7)

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 40% 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 3 years of data.
| Year | Math SGP | ELA SGP | Students (math / ELA) |
|---|---|---|---|
| 2023 | 41 | 43 | 34 / 32 |
| 2024 | 40 | 29 | 40 / 41 |
| 2025 | 36 | 44 | 46 / 46 |
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.

School Alpha
School Alpha is the residual between actual and expected performance once school context is held constant. It is a context-adjusted estimate, not a causal claim about teaching quality. Its reliability shows up on the page as the confidence label and the rank interval, not as a standalone statistic.

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.
