General Information
Progression Plans are intended to provide a general road map related to the sequencing of courses. The use of Progression Plans does not constitute a contract with the University. Progression Plans are a planning tool to help you define a pathway towards degree completion.
The NAU academic catalog is the official, authoritative source for all academic requirements and policies. Any discrepancies in curricular requirements from other sources will default to the academic catalog as the official, authoritative source. For a full description of degree requirements and course descriptions, refer to the Academic Catalog (link at the top of the page).
Some courses may have prerequisites and/or require an appropriate placement score (i.e. Mathematics and English). If you do not have the prerequisite course(s) or placement, you may have to take more courses than are presented on the Progression Plan.
If you are an NAU student, Jacks Planner (an interactive version of progression plans) may be available to you. To get to Jacks Planner, log into your Student Center in LOUIE and click on Jacks Planner.
