Prerequisites and Corequisites


A prerequisite is a course or qualification that must be satisfactorily completed before you may register for another course. The skills or knowledge provided in the prerequisite course has been deemed necessary for your success in the subsequent course. A minimum grade of “C” or “Pass” must be earned in the prerequisite course.

Prerequisites are enforced at Southwestern College. If you have not met the listed prerequisites, you will not be able to enroll in courses requiring the prerequisites. Prerequisites may be met by satisfactory completion of courses at Southwestern College or equivalent coursework at another college or university. Some prerequisites may also be fulfilled by satisfactory results on the appropriate validated Southwestern College assessment. If prerequisites were completed at another college or university, you will need to bring copies of appropriate transcripts/grade reports and/or assessment results to the Assessment Center to clear the requirements prior to registration. Transcripts for prerequisite clearance may be unofficial or official.  However, please note that for all external credit coursework to be formally evaluated for graduation, official transcripts must be mailed directly to Southwestern College from other institutions attended.  The Assessment Center is located in the Cesar E. Chavez Student Services Building. Students may challenge prerequisites. For more information, see Requisite Challenge section (BP 7025).


A corequisite is a course which must be taken during the same semester as another course. In other words, when a course has a corequisite listed, you must register for those courses (often a lecture and lab) concurrently. Knowing the information being presented in the corequisite course is deemed necessary for successful completion of the other course(s).

Corequisites are enforced at Southwestern College. If you do not enroll in all listed corequisites, you will be dropped from the courses requiring the corequisites. Similarly, if you are enrolled in courses that are corequisites and you drop one course, you will be dropped administratively (or by computer) from the other course. Students may challenge corequisites. For more information, see Requisite Challenge section (BP 7025).

Limitation on Enrollment

A limitation on enrollment may be any of the following:

  • A tryout or audition required prior to enrollment in a course that includes public performance or intercollegiate competition (including, but not limited to, band, orchestra, theater, competitive speech, chorus, journalism, dance, and intercollegiate athletics).
  • Enrollment in an honors course or an honors course section.
  • Blocks of courses or blocks of course sections for which enrollment is limited so that a group of students will enroll together in that set of classes. Students are participants in a special program such as a Learning Community or Puente.
  • A limitation that restricts enrollment because of statutory, regulatory, or contractual requirements. For example, some courses may require a student to have a valid driver license, health clearance, nursing license, certificate, etc.

Limitations on enrollment are enforced at Southwestern College. Students may challenge limitations on enrollment. For more information, see Requisite Challenge below (BP 7025).

Requisite Challenge

The Requisite Challenge Form allows students to challenge any course requisite. You may file a challenge based on one or more of the following reasons:

  • You have the knowledge or ability to succeed in the course despite not meeting the course requisite. You must provide documentation that explains/demonstrates that you have the background, skills, or abilities to succeed in the desired course.
  • You believe you will be subject to undue delay in attaining the goals of your educational plan due to a limitation on enrollment or because the prerequisite or corequisite course has not been made reasonably available. Consideration is typically given only when either:
    1. the prerequisite/corequisite has not been offered for two consecutive semesters or
    2. the prerequisite/corequisite is necessary for graduation, transfer, or a certificate, but the requisite is unavailable due to the number of course sections offered.
  • You believe the prerequisite, corequisite, or limitation on enrollment has been established in violation of Title 5 regulations and/or the Southwestern Community College District’s process for establishing prerequisites, corequisites, and limitations.
  • You believe the prerequisite, corequisite, or limitation on enrollment is discriminatory or is being applied in a discriminatory manner.

Students may file a Requisite Challenge Form through the Assessment Center. You must provide compelling evidence to support your challenge, attach documents (transcripts, evidence of work experience, etc.), and information necessary to support the challenge. The Requisite Challenge Form will be forwarded to the appropriate School Dean or designee for determination. Ten working days (15 days during summer) subsequent to your submitting the challenge form, results may be picked up at the Assessment Center or, at your request, the results will be emailed to you.

A student wishing to appeal the decision of the dean may request a meeting with the appropriate School Dean, Department Chair, and the Vice President for Academic Affairs or designee.

Recommended Preparation

Recommended preparation is previous training or coursework that helps a student successfully complete a subsequent course. Completion of the recommended preparation course with a grade of “C” or better increases student success. To improve your chances for success, you are strongly encouraged to follow recommended preparation whenever it is listed in the class schedule. Enrollment may not be denied to any student not meeting a recommended preparation.

Recommended Concurrent Enrollment

Recommended concurrent enrollment is a course that a student should complete—but is not required to complete—while enrolled for another course. Enrollment in such a course improves student success. You are strongly encouraged to follow recommended concurrent enrollment whenever it is listed in the catalog to improve your chances for success in Southwestern College courses. Enrollment may not be denied to any student not meeting a recommended concurrent enrollment.
