This page explains the function of and differences between co-existing sections and cross-referenced courses, with links to separate pages containing help information for each. 

Co-Exist vs. Cross-Reference Comparison

Co-Existing Sections

Co-existing sections exist when two different sections meet in the same room at the same time.


  • Relationships are created and managed through MAUI Planner at the Section level.
  • Courses may have unique course information (Title, Description, Hours, Etc.)
  • Course Numbers may be at different levels (A 2000-Level number and a 5000-Level number, for example).
  • Course Numbers may be from one unit or different units.
  • Enrollment count is managed be each individual section.
  • Courses which co-existed once do not have to co-exist each time they are offered.
  • Courses do not have a designated Administrative Home.


  • Co-existing sections can be from the same department/subject or different ones.
  • Related sections can co-exist with other related sections.
  • Co-existing sections must have identical information for Session Dates and Time/Day/Location. Credit Hours may differ.
  • Off-cycle section override dates do not automatically update on the new or co-existing section, and must be updated manually.
Cross-Referenced Courses

A Cross-Referenced Course is one course offered under multiple Subject/Course Numbers.


  • Cross-references are established, maintained and revised through the Course Approval Process in Course Library.
  • All course information (Title, Description, Hours, Etc.) will be identical, regardless of which Subject/Course number the student is enrolled under. 
  • All Subject/Course numbers must be at the same thousand-level, unless one of the numbers is in a Professional college (8000-9999).
  • The Subject/Course numbers must be from different units. A department cannot cross-reference two of its own courses. They may be from one or more colleges.
  • Any number of Subject/Course numbers may be included in a cross-referenced group.
  • When the course is offered, the Enrollment Count is an aggregate count of all students enrolled under all courses in the cross-referenced group.
  • All Subject/Course numbers will automatically be available to students every time the course is offered.
  • The Administrative Home must  submit course information in the MAUI Planner whenever the course is offered.


  • A cross-referenced course is offered in conjunction with at least one other Academic Department/Subject Code and Course Number.
  • Only the Administrative Home of a course can enter and submit the course offering information in MAUI Planner.
  • Non-admin home departments can initiate revisions through Workflow, which will then route to the Admin home.
  • Cross-referenced courses will have the exact same information for a session. Changing one changes any/all of them.
  • A cross-referenced course will appear in MAUI under each of the Subject Codes/Course Numbers, as well as in MyUI.
