COE Guidelines

The Collection of Evidence was approved as an assessment option that could be used for graduation purposes in 2006. Educators in the State of Washington requested the policies, rules, and support materials necessary to implement the assessment in their schools. The COE Guidelines are updated annually. Please use the 2014-2015 guidelines as your reference for policies and protocols for the COE.


In March 2006, the Washington State Legislature passed HB 6475, which authorized the Office of Superintendent of Public Instruction (OSPI) to implement three additional options for earning a Certificate of Academic Achievement (CAA). The three options are: GPA Comparison, a substitution of college-entrance or college-based+ test scores (ACT, SAT, AP) and a Collection of Evidence (COE).

The COE option is an evaluation of a set of work samples prepared by the student from a bank of state-developed performance tasks. The evaluation determines if a student is performing at the skill level required for high school graduation. Collections are scored at the state level by professional scorers trained by OSPI content specialists to ensure the validity and reliability of the assessment. The COE is designed to assess content and skills similar to those assessed on the corresponding large-scale state high school assessment.
