This brief presents validity evidence for using the ACT STEM score as an indicator of students’ readiness for college coursework in science, technology, engineering, and mathematics (STEM) disciplines.  \nA recent ACT research report suggests that academic readiness for STEM coursework may require higher scores than those suggested by the ACT College Readiness Benchmarks given that Calculus instead of College Algebra appears to be the typical first mathematics course of students majoring in STEM.2 The median ACT mathematics test score associated with a 50% probability of earning a B or higher grade in Calculus is 27. The typical first science course taken is largely dependent upon a student’s major, as evidenced by differences between  \nthe four STEM major clusters included in ACT’s definition of STEM.3 Based on performance in Chemistry, Biology, Physics or Engineering, the median ACT Science score associated with a 50% probability of earning a B or higher grade is 25. In comparison, the ACT College Readiness Benchmarks in mathematics and science are 22 and 23, respectively.4  \nTwo types of validity research are presented in this brief. The first involves identifying the ACT STEM score that is associated with a reasonable chance of success in first-year STEM-identified mathematics and science courses. This information can be used to help gauge overall student readiness for STEM-related coursework. The second type examines the ACT STEM score in relation to the likelihood of succeeding ina variety of STEM-related college outcomes:  \ncumulative grade point average (GPA) over time, persistence in a STEM major, and ultimately completing a STEM degree. These results illustrate that predicting student success in STEM-related fields is a valid use of the ACT STEM score.  \nACT Technical Briefs provide reliability, validity, and other psychometric analyses on ACT education and workforce development assessments, services, and programs and those of its partners.
