Course prerequisite and corequisite information

A prerequisite means a course or other requirement that a student must have taken prior to enrolling in a specific course or program.

A corequisite means a course or other requirement that a student must take at the same time as another course or requirement.

An advisement recommendation means a condition of enrollment that a student is advised, but not required to meet, before enrolling in a course.

When students register for courses the computer system will check for the pre- or corequisite required for the course they have selected. The system will check courses completed or in progress at SUNY Oswego, and transferred courses taken at other colleges that are equivalent to the pre/co requisite required at Oswego when they have been recorded from official transcripts.

If the student does not have the required pre/co requisite recorded or in progress the student will not be able to sign up for the course and will get a “pre-req error” message. If a student believes they have the appropriate pre/co requisite but receives the error message, they should contact their advisor to begin the Challenge Policy process.

The pre and co requisites for all courses can be found under the course descriptions in the College Catalog or by clicking on the course number within myOswego when doing a search of courses that are being offered. Current prerequisites that are enforced are in the online catalog.


In cases where the student does not meet a stated pre/corequisite of a course and there is no “or Instructor’s Permission” qualifier in the pre/corequisite description, the student may submit a Prerequisite Deviation Form to the home department of the course to seek approval for registering for it. A Prerequisite Deviation Form in such cases may require additional written documentation, such as; explanation of alternative coursework, background, or abilities that adequately prepares the student for the course. The signature of the student’s advisor and the department chair of the home department of the course or someone authorized to sign for the chairperson signifies approval of the deviation. A copy of the form will be kept in the student’s permanent folder at the Registrar’s Office.


Since the college may not have a record of coursework you may have completed at other colleges the pre/corequisite system won’t work the same way for you. SUNY Oswego has developed a process wherein you will be able to register for a course that has pre/corequisites and then later supply the instructor with evidence (ex. unofficial transcript) that you have met the pre/corequisite elsewhere. The process to do this is explained in your myOswego account when you go to register for courses. Once you have selected a course to take you will need to go to the “Prerequisite Registration Waiver” menu and enter the CRN for that course. Then you will need to register for the course. Note: The prerequisite waiver will not actually register you for the course (you must complete the waiver and register). After you are registered for a course with a pre/corequisite you must make sure to contact the instructor and provide evidence that you have completed the pre/corequisite at another school.


Course pre/corequisites will not be electronically enforced on graduate level courses. However, in the rare instance where a graduate student seeks to take an undergraduate level course they must go through the same process as non-matriculated students listed above.
