The Effects of Student-Teacher Ratio on Test Scores: Applying Ceteris Paribus to California and Massachusetts Schools

This paper seeks to analyze the impact of student-teacher ratio on test scores in California and Massachusetts. Since student-teacher ratio is just one of the variables affecting students’ learning outcomes, other attributes were taken into account for a comprehensive analysis. These attributes included percent of English learners, average district income, percent of students on free or reduced lunch, and expenditures per student. The data sets for both states were assessed both inherently and with ceteris paribus approach. The results indicated that while student-teacher ratio does affect test scores, other classroom variables have a significantly greater influence on students’ learning outcomes
