This school performs roughly as expected for its context.
Data confidence:Medium94 students tested 3 years89% 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: #474 of 675

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% | 14 | -12.7 |
| Students gain ground year over year | 30% | 44 | -1.8 |
| Equity within the school | 15% | 73 | +3.5 |
| Direction over recent years · thin data | 10% | 50 | +0.0 |

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 →

Achievement
Raw test performance
Bottom 30%
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 standard36%
- Level 2 — Approaching standard33%
- Level 3 — Meets standard (proficient)21%
- Level 4 — Exceeds standard10%
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 enough years yet
Trajectory will appear with 2025-26 data 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 6th grade here in 2019 gained 24 proficiency points by 10th grade — gaining, versus a metro median of about 0/yr.
Based on 3 cohorts across math + ELA.
Learning rate: +2.7 proficiency points/yr (no CI — too few cohorts)

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 56% 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 5 years of data.
| Year | Math SGP | ELA SGP | Students |
|---|---|---|---|
| 2018 | 71 | 44 | 175 |
| 2019 | 63 | 45 | 350 |
| 2023 | 65 | 44 | 106 |
| 2024 | 46 | 43 | 108 |
| 2025 | 51 | 62 | 80 |
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.
