The Educational Goal-Attainment Tests, in particular, were used in four large-scale undertakings that led to subsequent planning and development efforts. The first was a statewide study of Puerto Rican students in comparison to their black and white counterparts. Both urban and suburban samples were used with the emphasis on urban. These results, along with those of a second statewide study done primarily to assess the reliability of the tests, formed the basis for a statewide planning effort. These studies are used as illustrations of the applicability of group data for evaluation purposes and provide a basis for suggesting some of the necessary sampling strategies. An urban district used the tests as one ingredient in a full-scale evaluation study, and some of the methodologies of this study are described as exemplary of ways in which the tests may be employed. The use of these data for planning purposes will also be described. Finally, a suburban district used the tests to measure a set of goals different from, but similar to, the Phi Delta Kappa goals, in conjunction with a needs assessment. This required an added validation process and altered scoring. These procedures, along with the uses of the results for subsequent curriculum planning, illustrate the flexibility and usability of the approach for a variety of district needs. (Author/RC)
