Argument-Based Validation in Testing and Assessment

Argument-Based Validation in Testing and Assessment

February 2020 | 160 pages | SAGE Publications, Inc

Carol A. Chapelle shows readers how to design validation research for tests of human capacities and performance. Any test that is used to make decisions about people or programs should have undergone extensive research to demonstrate that the scores are actually appropriate for their intended purpose. Argument-Based Validation in Testing and Assessment is intended to help close the gap between theory and practice, by introducing, explaining, and demonstrating how test developers can formulate the overall design for their validation research from an argument-based perspective.

Chapelle’s “Argument-Based Validation in Testing and Assessment” is among the best-written texts on test validity. It is an up-to-date, cogent presentation from a logical – as opposed to strictly psychometric – perspective.
