Previous research has provided evidence for the utility of the Minneapolis Kindergarten Assessment (MKA), which is a measure of early literacy and numeracy skills. The present research was undertaken to replicate previous factorial results and evaluate the relative strength of an alternative parameterization of the measurement model, the bifactor model, which was posited to correct for anomalies found in the research literature. In addition, predictive validity evidence was ascertained to evaluate the extent to which two different factorial structures differed when making predictions about later reading and mathematics outcomes. Results suggested the bifactor model provided a useful measurement model conceptualization and also provided a strong predictive model for later reading and mathematics.
