The Collection of Evidence (COE) is a state approved alternative assessment.


The COE is an evaluation of a set of work samples based on classroom work, prepared by the student, with instructional support from a teacher. Passing a COE satisfies the assessment requirement for a specific content area and will contribute to earning a Certificate of Academic Achievement. This option is one of several available to Washington State high school students to fulfill assessment graduation requirements. Students must meet eligibility criteria to access the COE.

Students may submit a COE in Reading, Writing, Mathematics and/or Biology. Eligibility to submit a COE requires a student to have taken the applicable content area assessment one time without meeting standard prior to submitting a collection. See the COE Guidelines for 2014-2015 policies.

Collections must meet eligibility and sufficiency requirements to qualify for scoring. For eligibility requirements students should talk to their teacher and/or counselor.
