CASAS, in cooperation with the CASAS National Consortium Policy Council, conducted a study to provide guidance to program and instructional staff regarding student readiness to take the GED Tests. The study looked at the relationship of CASAS reading and math scores to official 2002 GED test results from five states--California, Hawaii, Iowa, Kansas, and Oregon. More than 6,700 individuals in the study took the appropriate CASAS test form within six months of taking the GED Tests. The study found a clear positive relationship between CASAS reading scores and GED reading scores as well as between CASAS math scores and GED math scores. The study also indicated a clear positive relationship between CASAS reading scores and overall GED results averaged across the five test content areas of reading, writing, science, social studies, and mathematics.
