Washington Comprehensive Assessment of Science
The Washington Comprehensive Assessment of Science (WCAS) measures the level of proficiency that Washington students have achieved based on the Washington State 2013 K-12 Science Learning Standards, which are the Next Generation Science Standards (NGSS). All students are assessed on their knowledge of the standards through the WCAS in grades 5, 8, and 11. The tests fulfill the federal Every Student Succeeds Act (ESSA) requirement that students be tested in science once at each level: elementary, middle, and high school.
