The Washington State Board of Education annually creates an achievement index for every school in the state. The index reflects how students fared on tests in reading, writing, math and science. It also considers extended graduation rates.

Improvement over the previous year's result also factors into the index, as does a comparison of how low-income and non-low-income students perform, and how the school's results stack up against others of similar demographics.

This database shows Southwest Washington schools' results for the 2010-11 school year.

The highest score is 7; the lowest is 1. Click here for a detailed chart of how the index is calculated.

You can select only a district to see all schools within it, or select a school from the dropdown menu after selecting a district.

If you leave both "school" and "district" set to "Any," and select a status, you will see all schools in the county that performed at that level.
