Portfolio assessment is a method of assessing student learning that involves collecting and evaluating a variety of student work over time. The purpose of portfolio assessment is to document student learning and growth over time, rather than to measure student achievement against a standard or to provide feedback to students on their work.

A portfolio assessment typically includes a collection of student work, a student self-reflection, and a teacher evaluation. The student work may include assignments, projects, tests, and other evidence of learning. The student self-reflection may include a statement of goals, a description of the student's learning process, and an evaluation of the student's own work. The teacher evaluation may include comments on the student's work, feedback on the student's progress, and suggestions for improvement.

Portfolio assessment offers a number of benefits, including allowing students to demonstrate their learning in a variety of ways, helping students to reflect on their learning and growth, and providing teachers with a more comprehensive view of student learning.

Portfolio assessment can be challenging for a number of reasons, including the time it takes for teachers to collect and evaluate portfolios, the difficulty students may have in selecting work that best represents their learning, and the difficulty in ensuring that portfolios are assessed fairly and consistently.
