Typical Profile

Students score highly, and the school still performs above expected for its context.

Data confidence:High625 students tested 4 years99% 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.

Raw test scores rank this school #125, 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 #161.

Each component below is scored on a 0–100 within-metro scale. A qualitative band summarizes where the school lands.

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.

Per-component contributions to this school's Decoded Rank composite. Weight is the share each component carries; percentile is the school's within-metro score on that component.

How the Decoded Rank composite is computed

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.

Bimodal distribution

Two distinct groups are visible: a strong cluster at the top and a struggling cluster at the bottom.

L1 19%

L2 20%

L3 28%

L4 32%

Level 1 — Below standard19%
Level 2 — Approaching standard20%
Level 3 — Meets standard (proficient)28%
Level 4 — Exceeds standard32%

Why this matters. A bimodal distribution often reflects two student populations served side-by-side (for example a gifted or honors track alongside a general-population cohort). Aggregate scores can hide this. Look at the school's program mix when comparing.

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.

Year-by-year decoded and achievement ranks. Pandemic-affected years are excluded — we don't interpolate scores across the gap.

Note: assessment transitions (where a state changes its test) are footnoted on the methodology page; trends are not computed across breakpoints.

Trajectory

Trending up

Based on 2 years (2024–2025).

Slope: +14.8 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.

Growth / Learning Rate

Not published by Washington.

Growth measures year-over-year progress for the same students tracked across grades — it needs longitudinal student-level records that the state has but doesn't release at the school level. Some states (CA, ID, TN) do publish this; Washington doesn't.

For this school, SchoolDecoder shows multi-year context another way: the Historical Ranks section below tracks how the school's Decoded Rank has moved over the years we have data for, and the Subject Rankings above break out math vs. ELA performance per grade. Both are cross-sectional, not the same as growth, but together they cover most of what a parent would use growth data for.

Student Growth (Washington)

Student growth percentile: the typical student here grew faster than 47% 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 4 years of data.

Year	Math SGP	ELA SGP	Students
2019	52	38	992
2023	59	53	1,128
2024	50	46	1,159
2025	51	43	1,146

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.

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.

Shrunk Alpha (95% CI): +0.14 (95% CI: +0.13 to +0.15)

SES index components

Tract % bachelor's+: 48.6%

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.
