Key findings of a pilot study of the Alaska Instructional Diagnostic System (AIDS) are summarized. The AIDS pilot test served to verify the appropriateness of the skills survey as well as the validity and reliability of the items. The AIDS testing system includes three components: (1) upper level skills surveys (grades 3-8); (2) lower level skill surveys (grades 1-3); and (3) reading and mathematics skill sheets (grades 1-8). Objectives and test items correspond to content taught in grades 1-8, but there are no specific levels. All pilot test levels include items covering reading and mathematics. The lower level skills are divided into levels one and two of the pilot test. The upper level skills are divided into three levels; in levels three through five, all items in the upper level skill survey are included. Objectives and subtests covered include: phonetic analysis, structural analysis; vocabulary building, reading comprehension, math computation, and math application. The difficulty of the five levels increase within each subtest area. The pilot study included 1658 students; generally a favorable response to the pilot test was indicated. Tabular data suggest high reliability and validity. Detailed tables and appendices are included. (Author/GK)
