The purpose of the study was to investigate the differences among reliability estimates of randomly parallel tests and their effects on Tucker non-random group linear equating. / The study was conducted using a sample of 988 tenth graders. One hundred 20-item tests were randomly generated from the students' response files. These tests were called "current" forms. Each of these randomly parallel forms was equated to each of five reference forms. / It was found that differences between reliabilities of current and reference tests had an effect on the accuracy of Tucker equating. The equating error was systematic and predictable. Larger differences in the reliabilities of test forms tended to produce larger errors. / Given an arbitrary unweighted error of.50, or a weighted error of.15, on the standard T-scale, a range of acceptable differences in reliability estimates was proposed for Tucker equating. Differences in the reliability of the current and reference tests of less than.025 produced negligible equating errors. / Source: Dissertation Abstracts International, Volume: 52-03, Section: A, page: 0890. / Major Professor: Jacob G.
