Abstract

The purpose of this study is to first assess the internal consistency reliability of the COR Advantage with Cronbach’s alpha for the entire scale and the Spearman-Brown prophecy formula for the subscales. The second is to examine the internal factor structure of the eight developmental domains by exploratory factor analysis. Results of the analyses yielded relatively high alpha coefficients ranging from .659 to .963. The exploratory factor analysis produced a two-factor solution that accounted for 47.22% of the variance. These results, with the exception of the Physical Development & Health developmental area having an alpha coefficient of .659, are indicative of a fairly reliable assessment. With an average alpha coefficient of .768, George and Mallery (2003), would classify this assessment as at least “acceptable” (p. 231).
