“…With respect to the former, the release of Gulliksen's (1950) Theory of Mental Tests deserves special mention for its codification of classical test theory. But more forward looking was work to create a statistically grounded foundation for the analysis of test scores, a latent-trait theory (Lord 1952(Lord , 1953. This direction would later lead to the groundbreaking development of item response theory (IRT; Lord and Novick 1968), which became a well-established part of applied statistical research in domains well beyond education and is now an important building block of generalized modeling frameworks, which connect the item response functions of IRT with structural models (Carlson and von Davier, Chap.…”

This book has documented the history of ETS's contributions to educational research and policy analysis, psychology, and psychometrics. We close the volume with a brief synthesis in which we try to make more general meaning from the diverse directions that characterized almost 70 years of work.Synthesizing the breadth and depth of the topics covered over that time period is not simple. One way to view the work is across time. Many of the book's chapters presented chronologies, allowing the reader to follow the path of a research stream over the years. Less evident from these separate chronologies was the extent to which multiple streams of work not only coexisted but sometimes interacted.From its inception, ETS was rooted in Henry Chauncey's vision of describing individuals through broad assessment of their capabilities, helping them to grow and society to benefit (Elliot 2014). Chauncey's conception of broad assessment of capability required a diverse research agenda.Following that vision, his research managers assembled an enormous range of staff expertise. Only through the assemblage of such expertise could one bring diverse perspectives and frameworks from many fields to a problem, leading to novel solutions.In the following sections, we summarize some of the key research streams evident in different time periods, where each period corresponds to roughly a decade. Whereas the segmentation of these time periods is arbitrary, it does give a general This work was conducted while M. von Davier was employed with Educational Testing Service.

“…Among various estimators of ability, the maximum likelihood estimator (MLE; Lord, 1953) has been a basic one. The maximum a posteriori or Bayes modal estimator (BME; Samejima, 1969, Chapter 2;Bock & Aitkin, 1981) is also familiar, where the standard normal prior is typically used.…”

Estimation of Ability Using Pseudocounts in Item Response Theory

A method for estimation of ability using pseudocounts in dichotomous item response models is given when associated item parameters are known or estimated by a separate calibration sample of examinees with the size of an appropriate order. The pseudocount minimizing the asymptotic mean square error is algebraically obtained. Though the pseudocount depends on unknown ability, a fixed lower bound for the pseudocount is derived under the logistic model with equivalent items. The lower bound is numerically shown to be reasonable under the 3-parameter logistic model with and without model misspecification.
