This study investigated Grade 9 students’ attitudes towards science, technology, engineering, and mathematics (STEM) and the extent to which their attitudes impacted on their academic achievement in Integrated Science. An adapted Students’ Attitudes Towards STEM instrument (Friday Institute for Educational Innovation, 2012) was piloted on 67 high school students in Jamaica and yielded a Cronbach alpha value of 0.821. It was then administered to 259 Grade 9 students from four high schools.
