Approaches to sampling are suggested for use by states in reporting more effectively on the completers and leavers in vocational education programs. Following an introductory chapter, six others outline the proposed plan for followup studies. Chapter 2, a task outline for a proposed ongoing sampling survey, divides the first three of the followup years into fifteen steps, presented in chronological order, that show both the timing of operations for a given survey year and also how the final stages in completing one year's survey overlap with the preparatory stages for succeeding years. (Beginning year 4, the ongoing survey enters a repeat cycle of basically the same steps used in year 3 to complete each successive followup survey.) Chapter 3 lists details of the one-stage sampling plan and is divided into three sections: (1) method of selection, (2) proposed sample sizes, and (3) reliability of sample estimates. Chapter 4 gives approximate costs for the proposed one-stage survey design, speculated on the basis of experience in other studies. Chapter 5 deals with instrument development (a background questionnaire, a student followup questionnaire, and an employer instrument). Chapter 6 suggests how to achieve a high response rate from the mail questionnaire, and chapter 7 offers procedures for analysis of survey results. Topics appended are these: changing the sampling rate for an ongoing survey, interim procedures for obtaining followup data prior to the maturing of the ongoing survey, the development of a national sample of vocational schools and students, and VEDS questionnaires.
