Summary
Pertinent statistics and charts are presented on K-12 schools in Washington State. This site is devoted to analyzing school data to inform and assist parents, taxpayers and policy makers with their school related decisions. The current emphasis is analyzing school districts’ finances including teacher and administrator total compensation packages.

A Tour Of The School Data Project Site
The School Data Project is an independent, ongoing analysis of Washington State’s public K–12 education system — covering all 295 traditional school districts and roughly a dozen public charter schools. For each district and charter, the site presents detailed statistics on student academic performance, total annual per-pupil expenditures, historical enrollment trends, and total compensation for teachers and administrators.

Example 2: Rainier Prep Charter School
Reports Overview
The Reports section includes a variety of analytical summaries and tools:
1) School District Tax Measures
Washington State allows up to four local election dates per year (February, April, August, and November) when traditional school districts can propose tax measures. Public charter schools, however, cannot. In most districts, 100% of the State School Property Tax collected from local taxpayers goes directly to their local school district — meaning that roughly 50–70% of all property taxes fund local schools. And that is not enough. The State has to send more funds to each school district primarily from State Sales Taxes.
State School Property Taxes Report 2021-2022
A frequent misconception is that voters approve future tax rates; in fact, they approve tax amounts in dollars. Property tax rates are later calculated by county assessors to collect those approved amounts, based on the Total Assessed Value (TAV) of all taxable property within the district. Thus, rising property values do not necessarily mean higher taxes — and falling values do not necessarily reduce them.
The report explains this Proportional Obligation Factor (POF) method in detail and provides online calculators to help voters estimate actual tax impacts using sound accounting principles. Most school districts underestimate costs to taxpayers due to incorrect assumptions or flawed calculations.

2) Academic Performance Outliers
This report highlights schools that significantly outperform on state testing in English Language Arts (ELA), Math, and Science.
3) Student Growth Percentiles (SGP)
The SGP report measures how much students have improved academically compared to their academic peers statewide. This metric is especially helpful for understanding progress in charter schools, which often serve students entering several grade levels behind.

4) Total Per-Pupil Expenditures (TPPE)
Unlike the Office of Superintendent of Public Instruction (OSPI) reports — which exclude certain costs — this analysis includes all expenditures for a complete view of what is truly spent per student.

5) Teacher Compensation
This report details the median total compensation for teachers in each district, including cash salary, benefits, and pension funding — all taxpayer-funded.

6) Superintendent Compensation
Despite the McCleary Decision’s intent for the state to fully fund education, each district and charter school independently sets its own pay schedules. Superintendent salaries often exceed that of the governor, with no state-wide salary limits or accountability.

7) Recommended Policy Changes
Two key reforms are proposed:
Voters’ Pamphlet Representation: Currently, districts must recruit both pro and con committees for their own tax measures. In practice, they often fill only the pro side — usually with paid staff — leaving voters without a counterargument.
Transparency in Bond Campaigns: School districts are not bound by the Truth in Lending Act (TILA). Long-term bonds (often 20+ years) can double in total cost due to interest, yet campaign materials frequently omit these details.
