The College of Science at Oregon State University adheres to the university admission criteria stated in the OSU catalog. Admission is not automatic and is at the discretion of the College of Science. The College does not conditionally admit at the post-bacc level. 

Contact Heather Arbuckle, head advisor for the College of Science, for detailed information.


Applicants for consideration must meet the same GPA requirements as transfer applicants. These include:

  • Completion of WR 121 and MTH 111 with a C- or better
  • English proficiency as demonstrated by a passing TOEFL score.
  • A minimum GPA of 2.25. Students with a GPA of 2.25-2.75 will be reviewed for the following criteria and MAY be admitted at the discretion of the College of Science:
    1. Strength of undergraduate preparation;
    2. Evidence of improved GPA in the last two years; Exemplary service such as military service, Peace Corps, AmeriCorps, etc.;
    3. Evidence of maturity and commitment to a new major.

Students who are not admitted to post-baccalaureate status may still take classes at Oregon State University as non-degree students. Any subsequent admission decision will then be based on the GPA from the first degree plus any subsequent credits earned.


The following deadlines will be enforced for post-bacc applications to the College of Science. All pre-requisite coursework must be completed by this date:

  • August 1 for Fall Term
  • November 1 for Winter Term
  • February 1 for Spring Term
  • May 1 for Summer Term

Post-Baccalaureate Programs in Pre-Professional Health Sciences

Further criteria apply for admission to the post-baccalaureate programs in the pre-professional health sciences. Applicants to other pre-professional programs such as pre-pharmacy, pre-vet, dental, nursing, physician assistant, and physical therapy must show similar aptitude and dedication. Such students may be asked to submit additional materials to show suitability for the desired major. International students are cautioned that acceptance into U.S. medical schools is very competitive and non-U.S. citizens are rarely accepted. Additional information on the post-baccalaureate pre-medical program is available.

The Post-baccalaureate pre-professional health sciences programs at OSU admits students who have a high probability of success in gaining entrance to medical school. Such indicators include:

  • High grades in previous science courses attempted (3.0 minimum);
  • Overall academic success (3.0 minimum);
  • Demonstrated commitment to the profession of medicine.

Registration Information for Post-Bacc Students

New post-bacc students require a PIN to register and may not register until receiving a PIN from an advisor. Post-bacc students may be required to attend START at the discretion of the major department advisor. In the College of Science, new post-baccalaureate students may register after Phase II (after all currently enrolled students have registered). For Fall Term, Post-baccs may register on the first Transfer START Day. After the first registration, Post-bacc students must meet with an advisor and get a new PIN prior to each Fall Term registration. Currently enrolled post-bacc students register after Seniors during Priority Registration.

To reach an advisor, contact the appropriate College of Science department.

Post-bacc students are not required to complete the Baccalaureate Core at OSU, but must complete all major and College of Science requirements as well as OSU residency requirements in order to get a second bachelor’s degree (see Academic Regulation 26 & 27)
