Samuel Messick

Messick was born on April 3, 1931, in Philadelphia. He graduated from the University of Pennsylvania, where he earned a bachelor's degree, and he earned a PhD from Princeton University.[1][2]

Messick worked as a psychologist for the Educational Testing Service (ETS).[1] He examined construct validity. Messick influenced language testing in 2 main ways: in proposing a new understanding of how inferences made based on tests must be challenged, and in drawing attention to the consequences of test use.

Messick resided in Pennington, New Jersey.[1] He died on October 6, 1998, in Philadelphia, at 67.[1]

The Quantitative and Qualitative Methods division (Division 5) of the American Psychological Association created the Samuel J. Messick Distinguished Scientific Contributions Award to honor Messick's contributions. Douglas N. Jackson, a previous collaborator of Messick, earned the award in 2004.[3]
