Assessment and evaluation are related but distinct processes for measuring student learning. Assessment is an ongoing process aimed at improving student learning by collecting information over time through various methods, such as samples of student work, observations, and self-assessments. The results are reported using scales or levels rather than grades alone. Evaluation makes overall judgments about a program, course, or set of lessons by considering multiple sources of information such as test scores, assessment reports, and interviews. While assessment and evaluation are sometimes used interchangeably, evaluation has a broader focus on the overall experience, not just individual assessments. Testing is only one part of assessment, which is broader and looks at progress over time in various contexts rather than just results on a single test
