Educators have many assessment tools at their disposal, but a comprehensive process for screening and progress monitoring students may need refinement in order to make timely, accurate, and meaningful instructional decisions. In this session, participants will walk away with a better understanding of how to evaluate the sensitivity and specificity of math screener data in relation to state assessments; better understand the “gated screening approach” versus a one-time screener model; and determine optimal screening frequency and timing throughout the year. Lastly, attendees will learn how to establish a standardized progress monitoring environment to reduce measurement error, better compare mastery measurement of discrete skills with general outcome measurements, and learn best practices for graphing and interpreting data to make responsive instructional decisions.
