  • Where is the testing center?

    The testing center is located in the Viasat Engineering Pavilion at Cal State San Marcos.

    After a thorough evaluation of potential sites on campus, it was determined that the Viasat Engineering Pavilion would be the optimal location for several reasons. The Viasat Engineering Pavilion is conveniently located near parking, it does not share an HVAC system with any other facility on campus, and no in-person or hybrid courses or labs will take place in the facility during the semester.
