This report, which is based on an invited presentation given at the 2015 meeting of the Association of Test Publishers, is a response to the continuing proliferation of scale linking studies that have occurred since the publication of "Uncommon Measures" in 1999.The report has four parts. First, I restate the conclusions made in…

Test preparation plays an important role in high-stakes standardized testing. While test preparation companies may claim large, at times unrealistic, gains associated with product use, much of which can be very costly, scientific research supports a more moderate impact of test preparation. ACT offers a number of test preparation opportunities for…

Statewide testing with college admissions exams dates to 2001, when Colorado and Illinois introduced the practice. Such testing expanded in subsequent years, and beginning in 2017--2018, the Every Student Succeeds Act (ESSA) allowed states to use a college admissions exam to meet accountability requirements for high schools. Some see this option…

Best linear prediction (BLP) and penalized best linear prediction (PBLP) are techniques for combining sources of information to produce task scores, section scores, and composite test scores. The report examines issues to consider in operational implementation of BLP and PBLP in testing programs administered by ETS [Educational Testing Service].

As a condition of receiving federal funds, the Every Student Succeeds Act requires state education agencies to implement statewide assessments in mathematics and English language arts every year in third through eighth grade and once in ninth through 12th grade. The federal law also requires a science assessment once in each of three grade spans:…

High-stakes, standardized testing plays an important role in the lives of many students as they apply to college and compete for scholarships. In states where college readiness measures, like the ACT® test, are used for school and district accountability, the ACT scores of all students, whether college-bound or not, are a top priority for school…

An equating procedure for a testing program with evolving distribution of examinee profiles is developed. No anchor is available because the original scoring scheme was based on expert judgment of the item difficulties. Pairs of examinees from two administrations are formed by matching on coarsened propensity scores derived from a set of…

It is so easy to criticize the SAT that most observers overlook the weaknesses of its architect, the College Board. This author contents that, until the latter is replaced, however, the former will never be fixed. The College Board has every incentive to create a complex, stressful, expensive college admissions system. Because it is accountable to…

In order to remain relevant and useful, testing programs must periodically update their tests to match shifts in student populations and school curricula. One might think that because the publishers are offering a product, the responsibility for updates rests entirely on them. Publishers conduct studies to assure new content is appropriate. But…

It is time to replace the examination regime at 16 and 18 by something more appropriate. The coalition government has been solidifying its place by its Baccalaureate reforms at both ages, but this is a move in quite the wrong direction. Whatever the wider purposes that the examination system may serve, its core aim is to find out how well students…

This report summarizes five-year global GMAT testing trends and includes: (1) GMAT exams taken by citizenship; (2) GMAT exams taken by gender; (3) Mean age of GMAT examinees; (4) Mean GMAT Total score; and (5) GMAT score-sending breakdowns by program type (MBA, non-MBA master's, and doctoral/other), TY2014. This data brief can help build candidate…

Maintaining score stability is crucial for an ongoing testing program that administers several tests per year over many years. One way to stall the drift of the score scale is to use an equating design with multiple links. In this study, we use the operational and experimental SAT® data collected from 44 administrations to investigate the effect…

In many testing programs it is assumed that the context or position in which an item is administered does not have a differential effect on examinee responses to the item. Violations of this assumption may bias item response theory estimates of item and person parameters. This study examines the potentially biasing effects of item position. A…
