Longitudinal panel studies are widely used in developmental science to address important research questions on human development across the lifespan. These studies, however, are often challenging to implement. They can be costly, time-consuming, and vulnerable to test--retest effects or high attrition over time. Planned missingness designs (PMDs),…

Following the onset of the novel coronavirus disease 2019 (COVID-19) pandemic, daily life significantly changed for the population. Accordingly, researchers interested in examining patterns of change over time may now face discontinuities around the pandemic. Researchers collecting in-person longitudinal data also had to cancel or delay data…

We examine the American landscape of higher education quantitative research concerning how gender and sex demographic information is collected. We use a directed content analysis to examine the prevalence and operationalization of gender and sex among widely used higher education survey instruments. Our findings illuminate a seemingly haphazard…

The Teacher Compensation Survey (TCS) was a research and development effort by the National Center for Education Statistics (NCES) to explore the possibility of developing an administrative records survey that would compile compensation and demographic data on all public school teachers in the nation. A pilot survey in 2007 collected data from…

This project was a qualitative longitudinal research study into cultural and structural change in an English secondary school. The schools' consistent underperformance led to its conversion to "academy" status as part of a development under the Labour administration of 1997-2010. The Labour policy for academization was designed, first,…

This article describes issues in measuring school contexts with an eye toward understanding students' experiences and outcomes. I begin with an overview of the conceptual underpinnings related to measuring contexts, briefly describe the initiatives at the National Center for Education Statistics to measure school contexts, and identify possible…

The purpose of this article is to inform researchers about and encourage the use of longitudinal designs to further understanding of human resource development and organizational theory. This article presents information about a variety of longitudinal research designs, related statistical procedures, and an overview of general data collecting…

Missing data is endemic in much educational research. However, practices such as step-wise regression common in the educational research literature have been shown to be dangerous when significant data are missing, and multiple imputation (MI) is generally recommended by statisticians. In this paper, we provide a review of these advances and their…

To meet demands for accountability, most schools and departments of education at institutions of higher education (IHEs) gather information on their current students and graduates. This paper describes issues to consider when designing a longitudinal data collection and management system, drawing on seven years' experience developing such a…

Developmental science rests on describing, explaining, and optimizing intraindividual changes and, hence, empirically requires longitudinal research. Problems of missing data arise in most longitudinal studies, thus creating challenges for interpreting the substance and structure of intraindividual change. Using a sample of reports of longitudinal…

To test the effect of less-frequent interviews on data quality in longitudinal surveys, event history data from the National Longitudinal Survey of Youth 1979 regarding welfare and employment were analyzed. Due to the longer recall period, respondents failed to report short spells of welfare, employment, and unemployment. (SK)

Synthesizes information from a 1995 international symposium on longitudinal research in learning disabilities. Discussion of generic considerations of longitudinal research is followed by examination of issues specific to learning disabilities including definition, attrition, composition of research teams, ethical concerns, data collection, and…

This paper summarizes the data management techniques used in a large-scale longitudinal study of intensive, innovative programs. Emphasis is placed on the scope of data collection, the methods used in the study to keep track of students over several years, the techniques used to collect data about students in public schools, the quality control on…

Responds to a critique by Mudford, Hogg, and Roberts (1997) that raised concerns about the observation code used in a longitudinal research project to assess emerging behavior state patterns in young children with disabilities. Concerns about the thoroughness of the reliability data collected by Mudford are discussed. (Author/CR)

The information system of the American Council on Education (ACE), which comprises the basis for the ACE Higher Education Data Bank, is designed to collect and maintain biographical and other data on approximately 300,000 college freshmen each year for continuing longitudinal research based on subsamples of the students. The need for confidential…
