An Analysis of Objective Strength Patterns from the Iowa Test of Basic Skills.
The preparation and use of an objective strength analysis report (OSAR) from the Iowa Test of Basic Skills (ITBS) are described. The OSAR was designed to answer two needs: (1) a format which allows the school to easily answer the question "which reading objectives need more emphasis and/or better materials or techniques in order to raise its reading scores"; and (2) an easy comparison between grades and through time in order to detect consistent strengths and weaknesses. A sample report from a real school, with a fictional name, is appended. An examination of the sample report shows that the ITBS divides the Reading Comprehension subtest into three conceptual subskills and 16 objectives. In this case, the OSAR shows seven strand scores for each of grades 3-8. These strands were chosen such that an average of six to 10 items are used to assess a conceptual area having some continuity across grades. Districts obtain the ITBS group item performance reports on a building-by-building basis. Copies are made for each basic skills teacher for the grades being assessed. (RL)
