What's New?

COE Mathematics and Biology scores from the June submission will be posted on WAMS on August 29, 2014. Please call your district assessment coordinator for the WAMS score results. 

2014-15 guidelines will be released September 1st. 
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 assessments options available to Washington State high school students. Students must meet eligibility criteria to access the COE.

Starting in 2013-2014 students may submit a COE in Reading, Writing, Mathematics and/or Biology. They may submit only one collection per content area during their high school education. Eligibility to submit a COE requires a student to have taken the High School Proficiency Exam (HSPE) in reading and/or writing or End of Course (EOC) in mathematics and/or biology two times without meeting standard prior to submitting a collection. See the COE Guidelines for 2013-2014 policies.

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