Portfolio Assessment

Portfolio assessment evaluates learning through a purposeful collection of a student's work assembled over time rather than through a single test. The portfolio may showcase best work, document growth, or demonstrate mastery against standards, and typically includes student selection and reflection. Articulated for education by Arter and Spandel and stress-tested in large-scale programs analyzed by Koretz, it captures authentic, complex performance that on-demand testing misses, while raising distinctive challenges for the reliability and comparability of scores.
