The Washington State Achievement Index is designed as a unified state and federal
system intended to meaningfully differentiate among schools. It is a snapshot of a school's performance based on statewide
assessments. We can compare how a school performs in reading, writing, math, science, and graduation rates. The achievement index
is a joint project between the State Board of Education
and the Office of the Superintendent of Public Instruction.
In July 2012, SBE and OSPI began to revise the Achievement Index to include student growth data and college and career readiness indicators. This
data will provide a better way to view school performance, measuring not only how many students meet state proficiency standards, but also how
much and how quickly students are learning.
News: New 2013 Achievement Indicator development is in progress. Estimated release 4/24/2014.
