WaKIDS: Kindergarten Readiness Assessment in Washington State

WaKIDS, the Washington Kindergarten Inventory of Developing Skills, assesses children across six developmental domains during the first two months of kindergarten. The dataset contains performance metrics aggregated by school, district, and student group, allowing for analysis of readiness trends and disparities. Columns such as StudentGroup, Domain, and DevelopmentLevel suggest the data likely contains detailed breakdowns of assessment results.

Use Cases

• Compare kindergarten readiness rates across different StudentGroup categories using Percent and MeasureValue.
• Analyze developmental progress by Domain (e.g., Literacy, Math) across schools using SchoolName and DistrictName.
• Track assessment outcomes over time using the schoolyear column.
• Identify geographic patterns in early learning using County, ESDName, and DistrictOrganizationId.

Strengths

• Assesses six specific developmental domains: Social-Emotional, Physical, Language, Cognitive, Literacy, and Math.
• Provides multi-level aggregation from state to individual school via OrganizationLevel and related ID columns.
• Available on multiple platforms, indicating established use and importance.

Limitations

• Key metadata such as row count, total size, license, and author are missing from all sources.
• Last updated dates conflict between sources, with some showing 2025-05-05 and others 2026-01-08.
• The dataset description is repeated verbatim across platforms, suggesting potential documentation gaps.
