California State University San Marcos accepts freshman applications each year between October 1 and November 30 for admission to the following fall term. Get started by reviewing the admission criteria below.

Who is a Freshman?

A first time freshman applicant is a prospective student who has not taken college courses after the summer following their high school graduation. First-time freshman applicants will be eligible for regular admission if they meet the following criteria:

  • Are or will be a high school graduate or complete a GED.
  • Meet the CSU admissions eligibility index based upon GPA in college preparatory classes and scores from the ACT or SAT Reasoning exam. Calculate your eligibility index.
  • Have completed required courses with grades of "C" or higher in the "a-g" college preparatory subjects by the end of spring. See the list of a-g courses.

For fall admission, all requirements and high school graduation must be completed by the end of the spring term. Courses completed in the summer after graduation will not be considered in the admissions evaluation.

  • Submit official ACT or SAT test scores to Cal State San Marcos before the end of January.
  • Check your application status on your MyCSUSM. You will need to activate your account using your CSUSM ID number. Your ID number will be emailed to you within two weeks of applying to CSUSM. Having trouble signing into MyCSUSM?

What Happens Next?

Over the next few months, special attention will be given to reviewing each application. Once an admission decision has been made, your MyCSUSM account will be updated.

Maintain Your Eligibility

Admission is based on self-reported information from your CSU Mentor application. Once you are provisionally admitted, we verify this information against your official transcript. Please make sure to report accurate information.

Your admission may be rescinded for any of the following reasons:

  • Your GPA or course grades are lower than what you reported on the application
  • Your eligibility index falls below what was required for admission
  • You miss any admissions deadlines
  • You earn D or F grades in any coursework needed to meet the a-g course requirements
  • You misreport or do not complete a required course


The web portal MyCSUSM provides you with access to your student records, including the status of your application for admission, transcripts and other admissions materials. You will need your user id number and password to sign into your MyCSUSM account. Your user id will be assigned after you submit the admissions application via CSU Mentor.

  • All default passwords are 8 characters and are capitalized in the following format:
  • first two letters of your legal first name,
  • first two letters of your legal last name,
  • last four digits of your user id.

For example, if your name is Jane Doe and your student id is 012345678, then your default password would be JADO5678.

Applicants Outside of Local Admission Area (Impaction)

Prospective students from outside of CSUSM's local admission area are welcome to apply for admission during the priority application period. However, because we receive more applicants than we have available spots, they will only be considered if enrollment space is available after local admission area applicants have been accommodated.
