In this study, we explored retest effects on test scores and response time for repeaters, examinees who retake an examination. We looked at two groups of repeaters: those who took the same form twice and those who took different forms on their two attempts for a certification and licensure test. Scores improved over the two test attempts, and…

The academic achievement gap is a persistent and pernicious educational challenge confounded with race and socioeconomic status. The achievement gap persists despite over three decades of interventions and federal, state, and local policies and initiatives meant to close it. We examine the achievement gap in one of the most diverse states in the…

In 2009, at the end of the 12-month Great Recession in the United States, the U.S. government established a college degree attainment goal for 60% of 25- to 34-year-olds to earn an associate's or bachelor's degree by the year 2020. In the same year, Lumina Foundation set a similar goal for 60% of 25- to 64-year-olds to earn a high-quality…

Although it is commonly thought that people who are bilingual have an advantage in the labor market, studies on this topic have not borne out this perception.The literature, in fact, has found an earnings penalty is associated with bilingualism--people who are bilingual often make less than people who are monolingual in similar jobs.

Two versions of a general method for approximating standard error of regression effect estimates within an IRT-based latent regression model are compared. The general method is based on Binder's (1983) approach, accounting for complex samples and finite populations by Taylor series linearization. In contrast, the current National Assessment of…

This study examined population invariance of equating functions over subgroups defined by ethnicity on a teacher certification test. Investigating subgroup equating invariance was important because the total group who took this test consists of two subgroups (i.e., Hispanic and non-Hispanic) and the Hispanic group is a distinctively more able…
