After a review of the disadvantages of linear models for estimating the probability of academic success from previous school records and admission test results, the use of a probit model is proposed. The model is illustrated with admissions data from the Ecole des Hautes Etudes Commerciales in Montreal. (Author/BW)

Nonlinear common factor models with polynomial regression functions, including interaction terms, are fitted by simultaneously estimating the factor loadings and common factor scores, using maximum likelihood and least squares methods. A Monte Carlo study gives support to a conjecture about the form of the distribution of the likelihood ratio…

In studies of change in education and numerous other fields, interest often centers on how differences in the status of individuals at the start of a time period of substantive interest relate to differences in subsequent change. This report presents a fully Bayesian approach to estimating three-level hierarchical models in which latent variable…

The distribution of person fit indices is not easy to describe in tests where the item sample is too small to conform to a theoretical asymptotic statistical distribution, particularly the normal N(0,1). In practice, it is always the fact and, consequently, it is difficult to get the critical percentile value indicating person misfit. First, we…

To more accurately reflect student attributes and enrollment patterns of today's freshmen, and to account for the impact of a new state-funded scholarship, this study expands the set of variables typically found in retention studies by putting greater focus on first-year academic performance, concurrent enrollment, financial aid support, and…

Recently NWEA completed a project to connect the scale of the Maryland School Assessment (MSA) with NWEA's RIT scale. One large school system participated in the study, using test information from a group of over 24,000 students enrolled in third, fourth and fifth grade who took both the MSA and NWEA reading tests in the spring of 2005.…

The economic reform policies are being introduced in India in phases since 1990. It demands for competent middle level skilled manpower in country. By keeping this in mind, National Council for Education, Research and Training (NCERT), New Delhi, India introduces a revised policy in 1992 and promotes vocational education. Today, several…

This working paper contains the overheads used in a seminar designed to introduce some basic concepts of statistics to nonstatisticians. The seminar has been presented on several occasions. The first part of the seminar, and the first set of overheads, deals with the essentials of statistics, including: (1) population, sample, and inference; (2)…

Research across seven very different states has shown that as schools get larger, the average achievement among economically disadvantaged students declines. A traditionally strong argument against smaller schools, however, is that they are too expensive. Large consolidated schools with narrowly specialized grade spans are typically offered as…

Survey data gathered from 230 respondents from a random sample of 500 Ohio public school teachers explores the association between teachers' practice of assigning grades based on nonachievement grading factors and teachers' pupil control orientation (PCI). Responding high school mathematics teachers provided information that relates to the use of…

Using data from the 1999 National Study of Postsecondary Faculty (NSOPF:99), this study examined how gender and race/ethnicity relate to a number of faculty outcomes and characteristics, including: salary, rank, tenure status, education, experience, institution type, teaching field, workload, and research productivity. The study focused on…

Admissions officers devote substantial resources to high school visits and other recruiting events. Economic theory indicates that the best measure of effectiveness is marginal productivity. Subjects in this study were applicants to a large, Catholic, urban university and all students who participated in recruiting programs in fall 2002.…

This report is based on a study in which a regression model was constructed to increase accuracy in enrollment predictions. A model, known as the Modified Regression Technique (MRT), was used to examine K-12 enrollment over the past 20 years in 2 New Jersey school districts of similar size and ethnicity. To test the model's accuracy, MRT was…

The Progress in International Reading Literacy Study (PIRLS) is a large international comparative study of the reading literacy of young students. The student population for the U.S. 2001 PIRLS (hereafter simply referred to as PIRLS) was the set of all fourth-graders in the United States, corresponding to the grade in which the highest proportion…

Reports on the results of applying a multivariate regression model of living arrangement choices to census data on the 1970 U.S. population of nonmarried, nonparenting adults. The central finding was that no special role for the elderly in living arrangement choices existed. (Author)
