Washington State English Learner Progress and Proficiency Metrics

2022-23 school year data tracks English Learner student outcomes across Washington's K-12 system. The dataset, published by data.wa.gov, disaggregates counts by grade level, school, district, and state. It includes metrics for students meeting standards and those making progress.

Use Cases

• Analyze disparities in MetStandardDAT rates across GradeLevel and Orglevel to identify schools needing targeted support.
• Model the relationship between ProgressingDAT and GradeLevel to understand typical progression paths for English Learners.
• Benchmark district-level performance by comparing organizationname aggregates of MetStandardDenominatorDAT and ProgressingDenominatorDAT.
• Track annual changes in English Learner outcomes by joining on SchoolYear and organizationid across multiple report card releases.

Strengths

• Data is disaggregated by school, district, and state level for multi-scale analysis.
• Includes 15 distinct columns covering performance metrics, denominators, labels, and organizational metadata.

Limitations

• Sample size and row count are unknown, limiting assessment of statistical power.
• Data is limited to a single school year (2022-23), preventing longitudinal trend analysis without external joins.
