Statewide test scores are publicly released on Report Card.
For families: WCAS Score Reports for families arrive in districts in early October.
For educators: Scores are available in the Smarter Reporting System (SRS) in late August. Trainings, resources, and SRS can be accessed from the Scores and Reporting section of the WCAP Portal.
The Achievement Level Descriptors (ALDs) describe the knowledge, skills, and processes that students should know and do at each tested grade. The ALDs were developed by educators and used to recommend the Scale Score Ranges for Levels 1, 2, 3, 4 on the WCAS to the State Board of Education.
Lessons Learned from Scoring Student Work
(Updated November 2023)
The Science Assessment Team shares observations about student responses for the Washington Comprehensive Assessment of Science (WCAS) field test items.
During their session at the virtual conference, the science assessment team shared design features and development processes for the Washington Comprehensive Assessment of Science (WCAS) that help ensure an equitable and accessible measurement of student learning. Updates on resources and professional development opportunities available to educators were included.
(Updated December 2019)
Students in grades 5, 8, and 11 took the operational Washington Comprehensive Assessment of Science (WCAS) for the second time in spring 2019. At this session, OSPI staff shared information and gathered session attendee questions and feedback on anything related to the WCAS. This effort will inform OSPI's continued development of resources and supports to inform learning and assessment outcomes for all students.
