Declaring a Major

CSULB students must meet precise major-specific criteria in order to formally declare a major. This requires that students begin as pre-majors and then declare the major if and when they complete the major-specific criteria. All students must have a declared major by the time they reach 60 earned units.

This applies equally to students who are:

  • Undeclared
  • Admitted into a "pre-major" and are requesting to declare the major
  • Requesting to change major
  • Requesting to add a major

Please see the major-specific requirements from Enrollment Services to declare a major within the College of Natural Sciences and Mathematics.

If you have additional questions regarding the major-specific requirements or would like to meet with an advisor to work with you on a timeline, please schedule an appointment.

Pre-Major Declaration Guidelines

First-time freshmen admitted as undeclared or admitted to a different college will be allowed to switch their pre-major to the College of Natural Sciences and Mathematics based on the criteria outlined in the Pre-Major Declaration Guidelines (PDF).


Appointments with the Center are for CNSM pre-major students only. For fully-declared majors, contact your major advisor.
