Washington Kindergarten Development Skills Report Card 2021-22

WaKIDS assessment data records observations of kindergarten students across six developmental domains: Social-Emotional, Physical, Language, Cognitive, Literacy, and Math. The dataset includes performance measures aggregated by student groups, schools, districts, and counties for the 2021-22 school year. It is published by the Washington Office of Superintendent of Public Instruction via data.wa.gov.

Use Cases

• Analyze correlations between StudentGroupType (e.g., race, socioeconomic status) and Percent scores across Domains to identify achievement gaps.
• Model kindergarten readiness by predicting DevelopmentLevel based on MeasureValue and Denominator counts for specific StudentGroups.
• Compare average Percent scores for Literacy and Math Measures across different County or DistrictName regions.
• Track changes in MeasureValue over schoolyear for specific OrganizationLevels to evaluate intervention programs.

Strengths

• Covers six standardized developmental Domains for kindergarten assessment.
• Includes granular breakdowns by StudentGroup, SchoolName, DistrictName, and County.

Limitations

• Sample size and row count are unknown, limiting statistical reliability assessments.
• Data is limited to a single school year (2021-22), preventing longitudinal analysis.
