Very confident. Please see our white paper on our website for more information. Every two years, Terrace Metrics seeks partners to volunteer deidentified academic and behavioral data. (The data is matched by student identification numbers only). For example, 2019 data collected from over 24,000 students in grades 3-12 found that for every step downward in the behavioral health curriculum, GPA decreased by approximately 10%, standardized test scores (ACT, SAT, MAP) were reduced by as much as 15%, and there were significant increases in behavioral difficulties (e.g., classroom disruptions, tardies, absences). These findings were quite similar to data collected from over 20,000 students in 2017.
