Use of the Rasch Model to Solve Data Problems Encountered by the California Assessment Program.
Hill, Richard K.
Four problems faced by the staff of the California Assessment Program (CAP) were solved by applying Rasch scaling techniques: (1) item cultural bias in the Entry Level Test (ELT) given to all first grade pupils; (2) nonlinear regression analysis of the third grade Reading Test scores; (3) comparison of school growth from grades two to three, using the Reading Test; and (4) analysis of growth from grades two to three, based on the Reading Test, in the areas of word identification, vocabulary, comprehension, and study locational skills. Solution of the problems demonstrated that existing Rasch Models have practical significance and should be more widely used by educators. (MH)
