Does socioeconomic status explain the relationship between admissions tests and post-secondary academic performance?

Critics of educational admissions tests assert that tests measure nothing more than socioeconomic status (SES) and that their apparent validity in predicting academic performance is an artifact of SES. The authors examined multiple large data sets containing data on admissions and related tests, SES, and grades showing that (a) SES is related to test scores (r = .42 among the population of SAT takers), (b) test scores are predictive of academic performance, and (c) statistically controlling for SES reduces the estimated test?grade correlation from r = .

Comparative description of migrant farmworkers versus other students attending South Texas schools: demographic, academic, and health characteristics.

Little is known about academic performance, health, and social functioning of youth from migrant farmworker families. This study was designed to compare demographic, academic, health, and social data between migrant and nonmigrant youth residing in South Texas. Anonymous cross-sectional survey data were collected from 6954 middle and 3565 high school students.

Web-based data collection: detailed methods of a questionnaire and data gathering tool.

There have been dramatic advances in the development of web-based data collection instruments. This paper outlines a systematic web-based approach to facilitate this process through locally developed code and to describe the results of using this process after two years of data collection. We provide a detailed example of a web-based method that we developed for a study in Starr County, Texas, assessing high school students' work and health status.

Nontraditional work factors in farmworker adolescent populations: implications for health research and interventions.

Agriculture has been documented to be one of the most hazardous work environments for both adults and children. Adolescents may be especially vulnerable to adverse health effects from agricultural exposures due to the rapid growth and development experienced during those years. Separating the occupational, economic, and social issues in this population is difficult.

Comparative description of migrant farmworkers versus other students attending rural south Texas schools: substance use, work, and injuries.

Context: Little is known about substance use, work characteristics, and injuries of youth from migrant farmworker families. Some evidence suggests that migrant youth may be at greater risk for substance use and work-related injuries than nonmigrant youth.

Purpose: The aim of this study is to compare substance use, employment, and injury data from migrant and nonmigrant youth residing in rural South Texas.
