REGIS - Caltech's Web Enrollment System

Welcome to REGIS, the Registrarís Information System. All undergraduate and graduate students* will use REGIS to enroll in courses during the registration period and advisers will provide schedule approvals using REGIS. All students may view their unofficial transcripts and request official transcripts online; undergraduates can also run their degree audits and change their catalog years in addition to viewing their Freshman Progress Report during their first year.  Advisers and selected department personnel can view their advisees' unofficial transcripts and degree audits as well.  In addition, instructors and TAs can view Class Roll Sheets and enter Freshman Progress Reports through REGIS. Please note that REGIS is not a replacement for face-to-face meetings between students and advisers.

The Student Affairs Division, Office of the Registrar, and IMSS solicit your suggestions for enhancing web enrollment and other student services as we move forward to utilize technology to provide better service to the Caltech community. Comments and feedback can be sent to
