places from achievement to Decoded Rank

Decoded performance is roughly in line with expectations for this school's context.

Data confidence:High269 students tested 8 years98% 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: #206 of 462

in Portland-Vancouver-Hillsboro, OR-WA schools

Raw test scores rank this school #294, but after accounting for context, students here outperform what the data would predict. The Decoded Rank places it at #206.

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.

Students at this school cluster closely on the proficiency ladder.

  • Level 1 — Below standard39%
  • Level 2 — Approaching standard26%
  • Level 3 — Meets standard (proficient)26%
  • Level 4 — Exceeds standard9%

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 up

Based on 3 years (2023–2025).

Slope: +5.7 pct/yr (95% CI -70.9 to 82.3)

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 3rd grade here in 2015 lost 26 proficiency points by 5th grade — declining at about the metro median rate.

Cohort-to-cohort variance is high — interpret the headline cautiously.

Learning rate: -0.9 proficiency points/yr (95% CI -10.3 to 8.4)

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.

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.

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.

Cross-state metro note: This metro spans state lines. Both states use Smarter Balanced assessments with a common scale for grades 3–8 ELA/math. Context-adjusted ranks are computed within each state's testing context, then aggregated across the metro.
