    The Universal Screeners for Number Sense (USNS) measure the construct of number sense, which has been characterized in numerous ways over the last 50 years. A purpose of this study is to provide validity evidence regarding the USNS assessments, which may support scholarship on numeracy and practical work in K-12 schools. Findings indicate that the USNS assessments may be used confidently to measure students’ growth in number sense.
