Many low-income young people are not reaching important milestones for success (for example, completing a program or graduating from school on time). But the social-service organizations and schools that serve them often struggle to identify who is at more or less risk. These institutions often either over- or underestimate risk, missing…

The purpose of the recently proposed "p[subscript rep]" statistic is to estimate the probability of concurrence, that is, the probability that a replicate experiment yields an effect of the same sign (Killeen, 2005a). The influential journal "Psychological Science" endorses "p[subscript rep]" and recommends its use…

The GGUM2004 computer program estimates parameters for a family of unidimensional unfolding item response theory (IRT) models. These unfolding IRT models predict higher item scores to the extent that a respondent is located close to an item on an underlying latent continuum. This prediction is often consistent with responses to traditional…

Despite several decades of activity, alcohol expectancy research has yet to merge measurement approaches with developing memory theory. This article offers an expectancy assessment approach built on a conceptualization of expectancy as an information processing network. The authors began with multidimensional scaling models of expectancy space,…

A key strength of latent curve analysis (LCA) is the ability to model individual variability in rates of change as a function of 1 or more explanatory variables. The measurement of time plays a critical role because the explanatory variables multiplicatively interact with time in the prediction of the repeated measures. However, this interaction…

The Kentucky Career Ladder Commission has funded a special project on "expected student achievement," to study the evaluation of teachers while avoiding the indefensible use of standardized student achievement tests. As proposed, the plan uses student achievement as one aspect of evaluation. The problem is in determining the degree to…

Describes the practice of federal evaluation of research impact through three approaches: retrospective methods; qualitative methods, including peer review; and quantitative methods. Recommended areas for study in federal research impact assessment are suggested, including predictive reliability, comparative studies, time and cost estimates,…

The McCarron-Dial System is useful for both vocational and clinical evaluation of neuropsychologically disabled adults. Five factors (verbal-cognitive, sensory, motor, emotional, and integration coping) are used to predict vocational competency, which is measured by work samples and behavior scales, during the first twelve months of a client's…

The Pre-Reading Assessment Inventory (PRAI) was designed to fill a need for a wide-range, individually administered diagnostic test of a child's prereading skills (especially auditory blending and segmenting), knowledge, encoding and decoding strategies, and understandings about the reading task. The test development was based upon the research…

Developed for application in Air Force weapons systems training programs, a research project investigated the methods, procedures, and data available for conducting cost and training effectiveness analyses (CTEA). The primary objective of the project was to develop a user-oriented procedure for early formulation of training programs that can be…
