The purpose of this study was to examine the measurement frequency of universal screening test with three time points. Especially, this study focused on comparing the two conditions: three time scores and every months scores. In this study, 47 first graders and 58 second graders from A elementary school were participated. Pearson product-moment correlation coefficients, logistic regression, and latent growth curve modeling were used for analyzing technical adequacy of korean
maze CBM. The result of this study supported that the measurement frequency with three time points were still reliable and valid, comparing the condition where korean maze CBM was repeatedly measured by month. Limitation and implication of research are discussed.
