The purpose of this study was to determine whether or not a relationship existed between school size and student academic performance in Idaho high schools. This study used the mathematics portion of the Idaho Standards Achievement Test (ISAT) taken by all 10th grade students in the spring of 2009 to compare academic achievement in students in small schools and students in large schools. Mean scores for proficient and advanced students were calculated and categorized into five school size classifications. For instance, 91% of all Boise High School (BHS) 10th grade students demonstrated proficiency in mathematics on the ISATs. In 2009, BHS had more than 1280 students and was categorized into the 5A school classification. The findings in this study offer suggestions about possible variables that affect student academic achievement in small and large schools; including, male and female students, attendance, resources and programs, and economic status.
