Abstract	The Woodcock-Johnson-III cognitive in the adult time period (age 20 to 90 plus) was analyzed using exploratory bifactor analysis via the Schmid-Leiman orthogonalization procedure. The results of this study suggested possible overfactoring, a different factor structure from that posited in the Technical Manual and a lack of invariance across both age ranges under study. Even when forcing the seven-factor fit, the structure was problematic. The results from the 20 to 39 age group displayed patterns of convergence with and divergence from the Technical Manual's structure. The results from the 40 and above age group were generally consistent with the Technical Manual's structure except for retrieval fluency. This study is consistent with the body of exploratory factor analysis structural validity evidence suggesting that contemporary tests of cognitive ability, particularly those based on Cattell-Horn-Carroll theory, are overfactored and lack alignment with their respective Technical Manual's presented structure.
