Washington State Student-Teacher Ratios by School District

Report card data tracks the StudentToTeacherRatio for every public school and district in Washington State from the 2017-18 through 2024-25 school years. The Washington Office of Superintendent of Public Instruction (OSPI) publishes this information disaggregated by School, LEA, and Educational Service District. This longitudinal dataset supports analysis of staffing trends across eight academic years.

Use Cases

• Analyze trends in StudentToTeacherRatio over eight SchoolYears to identify districts with improving or declining staffing levels.
• Compare TeacherTotal and StudentTotal figures across different County or ESDName regions to assess geographic disparities in educational resources.
• Validate reported ratios using the IsEEValidated flag to filter for quality-assured data points in policy briefings.
• Benchmark individual SchoolName or LEAName performance against state-level aggregates for accountability reporting.

Strengths

• Covers eight consecutive SchoolYears from 2017-18 to 2024-25, enabling longitudinal study.
• Disaggregated data at School, LEA (SchoolDistrict), ESD, and State OrganizationLevels allows for multi-scale analysis.
• Includes validation flag (IsEEValidated) and timestamps (DataAsOf) for assessing data quality and recency.

Limitations

• Unknown total row count and file size prevent assessment of dataset completeness and granularity.
• Geographic coverage is limited to Washington State, restricting national comparative analysis.
• Sample data is unavailable, making initial schema and value validation difficult prior to download.
