Washington Comprehensive Assessment of Science
The 5th, 8th, and 11th grade Washington Comprehensive Assessment of Science
(WCAS) will be administered for the first time in spring 2018. These tests
fulfill the federal (ESSA) requirement that students be tested in science once
at each level: elementary, middle, and high school.
The WCAS measures the level of proficiency that Washington students have achieved based on the Washington State 2013 K-12 Science Learning Standards, which were adopted in October 2013.

- Test Design and Item Specifications
The Test Design and Item Specifications documents describe how the clusters (stimulus and item sets) and standalone items for the WCAS are developed.
They include a technical description of the assessment that assures the assessment will validly measure the science standards in a reliable manner every year.
The documents include a small sample of specifications for each grade. The sample will continue to expand through the 2017–18 and 2018–19 school years until full Performance Expectation coverage is achieved.

- High School Testing Requirements
With the signing into law of House Bill 2224 the high school science assessment graduation requirement is postponed until the Class of 2021. This means that students in the Classes of 2017 through 2020 do not need to pass a science exam in order to graduate. The table below details the federal accountability (ESSA) and assessment graduation requirements (HB 2224) for the classes of 2018-2021.
