Admission to California Institute of Technology is selective and competitive and is based on a holistic review of application materials. There is no GPA requirement for admission but the GPA is a factor for admission. We are aware that average GPAs vary by institution. If there are special circumstances that have affected your GPA, please discuss them in your statement of purpose. Caltech does not have a minimum GPA requirement. However, most successful applicants have a US GPA of at least 3.5 on a 4.0 scale and/or are in the top 5 to 10% of their class. NOTE: We are not accepting submission of GRE scores for application to our graduate program. Self-reported GRE scores will not be considered.
