The term assessment and evaluation are quite different. For example, an evaluation is more focused on making a judgment or determination concerning the quality of a performance, work product or use of skills against a set of standards. Evaluations are designed for and intended to document the level of achievement that has been attained.
An assessment, on the other hand, is more focused on measuring a performance, work product, or skill in order to offer feedback to document strengths and growth and to provide directives for improving future performance. Assessments are nonjudgmental and are designed and intended to be helpful to produce improvement.
