How important are ACT subscores?

ACT subscores play a significant role when applying to competitive STEM programs, especially at institutions like MIT and Caltech. The Science and Math subscores receive particular scrutiny from admissions officers at technology-focused universities, as these scores help predict your potential success in rigorous STEM coursework.

While your composite ACT score creates an initial benchmark, selective STEM programs typically examine individual section scores to evaluate specific academic strengths. For engineering and science programs, admissions officers pay close attention to your Math and Science subscores, often looking for scores of 34 or higher to demonstrate strong quantitative abilities. Your Reading and English subscores also matter, as these reflect your ability to analyze complex texts and communicate effectively ? crucial skills for any STEM career.

Top technical institutions like MIT and Caltech consider your ACT subscores as part of their holistic review process. These schools want to ensure you can handle advanced scientific concepts while also possessing the communication skills needed for research papers and collaborative projects. A strong Math score paired with notably lower Reading or English scores might raise concerns about your ability to succeed in courses requiring extensive technical reading and writing.

Your subscores can also impact placement in first-year courses at many universities. Strong subject-specific scores might allow you to skip introductory classes or qualify for advanced sections. However, remember that ACT scores are just one component of your application. Research experience, advanced coursework, and STEM-related extracurricular activities carry significant weight in admissions decisions for top technical programs.
