Schools need universal screening measures in mathematics, but there is little research evaluating these measures in mathematics. The main purpose of this current study was to develop the mathematics universal screening measure in grade 1 and evaluate the reliability and validity of the measure in the 2015 revised national curriculum in mathematics. The participants were 112 students attending the first grade of A elementary school in B city. Given the general characteristics of universal screening measures, screening measures were administered 6 times per year (3 times per semester). In addition, the mathematics comprehensive assessment administered at the end of December was used to evaluate the criterion and predictive validity of universal screening measures. The results of this study showed that slopes were sensitive to growth on performance. In addition, good evidence of reliability and validity was found for universal screening measures. Collectively, this study supported the evidence of the technical adequacy of universal screening measures in mathematics. Practical implications and directions for future research are discussed.
