The aim of the National Assessment of Educational Progress (NAEP) Supplementary Frame Assessment is to locate and assess samples of seventeen-year-olds no longer participating in the regular school curriculum. In this way a sample representative of the entire age group may be obtained for assessment purposes. Phase I of the study dealt with the acquisition of lists of eligible individuals from their high schools, while Phase II involves their location and assessment. Methods for obtaining changes of address, numerous field procedures for locating the individual, procedures for determining the individuals eligibility to take part in the assessment program upon the basis of stated criteria, and instructions for the administration of test packages, form the basis of this manual. Once located, the individual has to be persuaded to take part in the program, thus, interviewing techniques are stressed. Instructions are given for the administration of the Individual Screening Questionnaire (ISQ)- an inventory for eliciting background information, test packages and package supplements, and for the disbursement of incentive payments. The coding and gridding of questionnaires and assessment packages, other administrative tasks and methods of expense reimbursement are also outlined.
