Welcome to Caltech Accessibility Services for Students (CASS)!

Caltech is committed to maintaining a diverse academic community, and welcoming individuals with a broad spectrum of talents and experiences to its campus and programs. Students with disabilities, actively participating in all aspects of the Caltech experience, are an essential part of that diversity.

CASS will make every reasonable effort to provide academic adjustments and other reasonable accommodations to otherwise qualified students with known disabilities, consistent with Caltech's obligations under applicable law; including the Americans with Disabilities Act (ADA) of 1990, and Section 504 of the Rehabilitation Act of 1973. Our goal is to provide students with disabilities equal access to all Institute programs, activities and services. To that end, we seek to balance the student's right to access with our obligation to protect the integrity of Institute programs, activities and services.

Information about the registration process and relevant forms can be found below. Please contact us if you have any questions.
