Psychometrics and Psychometricians in the 20th and 21st Centuries: How it was in the 20th Century and How it is Now

This article is based largely upon the author's invited address at the 113th annual convention of the American Psychological Convention, Washington, DC, as the 2005 recipient of the Samuel J. Messick Award bestowed by APA Division 5 and the Educational Testing Service. The author summarizes the growth of graduate training in psychometrics and quantitative psychology, in the years prior to and following the end of WWII. He then opines the steady decline in the training of psychometricians and quantitative psychologists beginning in the 1970s and continuing into the 20th century. Likely causes of the decline are inferred and prospects for strengthening the quantitative skills of doctorates are discussed, including recommendations for reversing the downward trend.
