Open Door

During both Summer and Winter Intersession SSU opens its door to high school students, all college students, and working professionals. We invite you to come and study with us; no formal admission required.

Due to the current COVID-19 pandemic, our office has moved to telecommuting only operations and we are unable to accept credit card payments over the phone. During this time, please complete this online Open Door Registration Form (available between Monday - Friday, from 8am-noon only) and we will get back to you when we can register and collect payment from you. Thank you very much for your understanding.

No Formal Admission Required

Open Door is a registration policy whereby students who have not been formally admitted to Sonoma State may participate in Summer Session and Winter Intersession academic credit courses.


While the pre-requisites for many courses are waived during Winter Intersession and Summer Session, Open Door registration for some courses is subject to the approval of the associated academic department. If a course has pre-requisites listed in the course description, please check with the academic department to see if you meet the requirements.

Please note: all prospective Open Door students wishing to enroll in Business Department classes will need department approval.

Enrollment Eligibility

Open University/Door may be right for you if you:

  • missed the deadline for admission to SSU degree programs
  • want to update your professional training and job skills
  • want to explore personal interests
  • want to test your interest in a field before entry
  • have been academically or administratively disqualified at SSU or another CSU

Foreign/International Students

Open Door registration is open to permanent residents and those maintaining valid non-immigrant visa status, including, but not limited to F-1/F-2 student visa and J-1/Au Pair visa holders. Sonoma State University will not issue immigration documents for attendance through Open Door registration.

Students must demonstrate proof of English proficiency by one of the following options:

  • TOEFL (Test of English as a Foreign Language): A minimum score of 61 for undergraduate courses or 80 for graduate courses is required. Sonoma State's ETS code is 4723.
  • IELTS (International English Language Test System): A band score of 6.0 will be accepted in lieu of TOEFL for undergraduate students.
  • TOEFL/IELTS is not required of those who have studied full-time for three or more years at the secondary level or above at an institution where English is the principal language of instruction. Official transcripts are required.

International students must also obtain written approval from the International Student Advisor, located in the Center for International Education in International Hall, prior to enrolling through Open Door.

Disqualified Students

Matriculated students (admitted to SSU) or students who have previously attended SSU who have been academically disqualified may enroll in Summer Session and Winter Intersession courses through Open Door registration.


Open Door enrollment fees are due at the time of registration.

Drops, Withdrawal, and Refunds

Non-attendance does not constitute withdrawal. Intersession and Summer Session classes may be dropped for a full refund up until the last business day before the 1st day of instruction. Students may drop on the 1st or 2nd day of instruction for a 65% refund. The last day to withdraw is the 3rd day of instruction; a grade of W (Withdrawn) will appear on your SSU record and there will be no refund.

Open Door students must contact SEIE Customer Service to drop a class.

Grade Mode Change

Some courses have an option for students to receive a letter grade or Cr/NC; otherwise, the course description in the catalog will specify. Students may change their grade mode up to the end of the 2nd day of instruction, using the form at the SEIE office.

Credit Information

Open Door students receive Special Sessions academic credit for courses numbered 100–599; please note that Special Sessions credit does not meet degree residence requirements. In the CSU, up to 24 units of Special Sessions academic credit may be applied toward a Baccalaureate degree. Nine units may be applied toward a Master's degree (subject to departmental approval). Please consult with your home institution about how SSU Intersession/Summer Session academic units will apply to your degree.

Grades & Transcripts

All University rules and regulations pertaining to grades and transcripts apply to Open Door students; see University grading policies.

Open Door enrollment grades are available by requesting either an unofficial or an official transcript from the Sonoma State University Registrar’s Office. Unofficial transcripts may be requested in person only at the Registrar’s Office. Official transcripts may be requested by submitting a transcript request form to the Registrar’s Office.

Please note that Open Door students will not have access to online student services except for their Canvas online classroom space (if your class is using one).
