The continued accumulation of validity evidence for the intended uses of educational assessment scores is critical to ensure that inferences made using the scores are sound. To that end, the College Board has continued to collect college outcome data to evaluate the relationship between SAT® scores and college success. This report provides updated…

Dropping out of high school is related to a number of negative outcomes. For example, the median income of persons ages 18 through 67 who had not completed high school was roughly $26,000 in 2013. By comparison, the median income of persons ages 18 through 67 who completed their education with at least a high school credential (i.e., a regular…

Background/Context: Principles of evidential reasoning have often been discussed in the context of educational and psychological measurement with respect to construct validity and validity arguments. More recently, Mislevy proposed the metaphor of assessment as an evidentiary argument about students' learning and abilities given their…

We propose a new limited-information goodness of fit test statistic C[subscript 2] for ordinal IRT models. The construction of the new statistic lies formally between the M[subscript 2] statistic of Maydeu-Olivares and Joe (2006), which utilizes first and second order marginal probabilities, and the M*[subscript 2] statistic of Cai and Hansen…

Under certain conditions, statistical evidence is more persuasive than anecdotal evidence in supporting a claim about the probability that a certain event will occur. In three experiments, it is shown that the type of argument is an important condition in this respect. If the evidence is part of an argument by generalization, statistical evidence…

"Uneducated Guesses" challenges everything our policymakers thought they knew about education and education reform, from how to close the achievement gap in public schools to admission standards for top universities. In this explosive book, Howard Wainer uses statistical evidence to show why some of the most widely held beliefs in…

Using institutional data on race-specific college enrollment and completion, I examine whether minority students were less likely to enroll in a four-year public college or receive a degree following a statewide affirmative action ban. As in previous studies, I find that black and Hispanic enrollment dropped at the top institutions; however, there…

This article details the experimental research on frame effects that provides quantitative evidence that some types of frames have a greater ability to move and affect policy support than others. This method is particularly useful in showing the magnitude by which exposure to alternative ways of thinking about social issues alters the public's…

Using data from Achieving the Dream: Community Colleges Count, this issue of "Data Notes" investigates the number of attempts it takes students to complete all developmental education courses to which they are referred. Subsequent gateway course completion and overall persistence are also examined. Three-year outcomes were analyzed and…

The research summary "Successful, Safe, and Healthy Students" presents the research background for the Obama administration's proposals for comprehensive, community-wide services in high-poverty neighborhoods, extended learning time, family engagement and safe schools. While these policies have broad and common-sense appeal, the research…

"Data Notes" is a bimonthly publication that examines data to illuminate the challenges facing Achieving the Dream colleges and to chart their progress over time. Gateway courses generally include the first college-level English and math courses students are required to take. Increasing the number of students who attempt gateway classes…

Using data from Achieving the Dream: Community Colleges Count, this issue of "Data Notes" highlights some of the differences that exist between states. In addition to Achieving the Dream data, this report includes data from the U.S. Department of Education's Integrated Postsecondary Education Data System (IPEDS) for the 2008-09 academic year to…

Using data from Achieving the Dream: Community Colleges Count, this issue of "Data Notes" looks at three-year enrollment and attainment outcomes of students who persist through their first year. Additionally, first-year persisters (FYPs) were grouped based on the interaction of several student characteristics; analysis was conducted to…

Using data from Achieving the Dream: Community Colleges Count, this issue of "Data Notes" looks at students who returned to their original Achieving the Dream institution after completing credentials or transferring to another institution. Forty-two percent of students who either received a degree or certificate or transferred from an Achieving…

Using the data from Achieving the Dream: Community Colleges Count, this issue of "Data Notes" is the second of a two-part series investigating the characteristics of late stop-outs--students who accumulate at least 30 credits within the first two years, only to stop out without completing credentials or transferring. The data show that male…
