In an effort to better assess student outcomes, such as higher-order thinking skills, creativity, and problem solving, many schools are adopting performance assessments at both the classroom and state levels. The portfolio resources bibliography lists 234 publications to assist educators who are experimenting with portfolio assessment, including theoretical articles and actual samples of portfolio systems. All grade levels are covered, as are many subject areas.

The 45 entries in this assessment bibliography include a variety of applications and topics: diploma examinations, portfolios, grade-level tests, discussions of issues, performance assessments, curriculum frameworks and sample exercises, project fair materials, scoring guides, performance tasks, the "ordered-tree technique," instructional goals, open-response questions, definitions of terms, and results of research studies.
