The Second Follow-Up Field Test (SFUFT) of the National Education Longitudinal Study of 1988 (NELS:88) was conducted in 1990 and 1991 by the National Opinion Research Center and the Educational Testing Service. The SFUFT evaluated free response items (FRIs) for possible inclusion in the Second Follow-Up Main Study (SFUMS) and tested survey instruments, procedures, and forms. This report focuses on a methodological examination of the SFUFT data and the questionnaires developed. The SFUFT included four major survey components: students, dropouts, parents, and school administrators. Four questionnaires and five cognitive tests were developed, including the: Student Questionnaire, Not Currently In School (Dropout) Questionnaire, Parent Questionnaire, School Administrator Questionnaire (SAQ), and Cognitive Test Battery. Most of the students surveyed were in the last half of their senior year in high school. The major purpose of the parent component field test was to gather sufficient observations for evaluating the performance of questionnaire items. Data were obtained from: 2,254 students in 94 schools (overall response rate of 70.5%); 108 dropouts; 506 parents (response rate of 73.5%); and 65 schools/principals. The results show that the goals set for this pretest effort were attained, the FRIs were successfully administered, and the FRIs measure the same/similar domains as do multiple-choice questions. Recommendations for implementation of the SFUMS are provided. Numerous tables and figures are included. Documentation of 1990 instrument development meetings, documentation supporting questionnaire experiment analyses and cognitive test analyses, and a summary of cognitive interviews are appended. (RLC)
