|Relationships between Schoolwide Instructional Observation Scores and Student Academic Achievement and Growth in Low‑Performing Schools in Massachusetts
|The Massachusetts Department of Elementary and Secondary Education (DESE), like other state education agencies and districts, recognizes that a key lever to turning around low-performing schools is the quality of instruction (Hill & Harvey, 2004; Hopkins, Harris, Watling, & Beresford, 1999). As part of the annual monitoring of state-designated low-performing schools, DESE’s external low-performing school monitors use Teachstone’s Classroom Assessment Scoring System (CLASS) tool to conduct observations. DESE’ external monitors rated low-performing schools on three domains of instruction—Emotional Support, Classroom Organization, and Instructional Support. This paper examines the relationships between these observation scores and academic growth and achievement within a school, after adjusting for the percentage of students with low incomes and the grade levels in these low-performing schools. Results show statistically significant positive relationships between schoolwide average observation scores for each instructional domain and school-level academic growth in both English language arts (ELA) and mathematics. On a 7-point scale, a 1-point increase in a school’s overall observation rating was associated with an increase in student growth of 4.4 percentile points of growth in ELA and 5.1 percentile points of growth in mathematics. For schoolwide achievement, which is measured by the percentage of students who met or exceeded expectations on the state assessment, results show a significant positive relationship between the classroom organization domain and ELA schoolwide achievement. There was no significant relationship between observation scores and schoolwide achievement in ELA for any other domain or for mathematics schoolwide achievement. The relationship between observation scores and current achievement levels may be weak because achievement levels may be influenced by many other factors including students’ prior achievement and the economic and social challenges their families face.
