The Collection of Evidence (COE) is one of the options approved by the state legislature to show that a student has the skills necessary to earn a Certificate of Academic Achievement (CAA) but has been unsuccessful in demonstrating them in a large-scale test.

The Mathematics Collection of Evidence (COE) constitutes a purposeful set of 6-8 Work Samples that, taken together, demonstrate an understanding of the skills and knowledge of mathematics content and process. The Mathematics COE is aligned with the Mathematics portion of the End-of-course (EoC). The Mathematics COE will be scored for comparability of content and complexity as aligned with the EoC as per the Content Targets and Process Targets and the Essential Academic Learning Requirements (EALRs). Mathematics COEs include both on-demand and extended-time tasks and prompts.

Mathematics tasks feature an assignment that poses a significant question or addresses an authentic topic or issue, thereby providing students with opportunities to demonstrate their best mathematics skills. These tasks and prompts are 'framed' according to skills and knowledge in the content strands and process strands and must allow an opportunity to demonstrate at least one content learning target and one process learning target. Mathematics tasks and prompts also indicate whether the work sample was completed in an on-demand or an extended-time setting. (excerpted from OSPI website).
1. The student understands and applies the concepts and procedures of mathematics.
2. The student uses mathematics to define and solve problems.
3. The student uses mathematical reasoning.
4. The student communicates knowledge and understanding in both everyday and mathematical language.
5. The student understands how mathematical ideas connect within mathematics, to other subject areas, and to real-life situations.
