The Fundamental Achievement Series (FAS) is designed to cover a range of ability from basic literacy to approximately the eighth grade. These tests are used in the employment or educational placement of adults and adolescents who have not been exposed to formal education, or the educationally disadvantaged. The FAS contains a Verbal and a Numerical section, each of which can be administered in 30 minutes. Although the ability to read the test is not necessary, since the instructions and test items are played on a tape recorder; both sections of the test rely, to a large extent, on reading ability. The FAS items measure basic skills such as reading signs, finding numbers in a telephone book, adding sales slips, and telling time. Items frequently included in traditional paper-and-pencil tests are also contained in the FAS. The correlations of FAS items with other achievement test items are presented. The test was administered to 61 clients in a vocational rehabilitation center, with some minor problems which are described. The relevance of the "everyday" FAS items may increase the motivation of disadvantaged adults taking this test; further development is recommended. (Author/GDC)
