As part of the semester conversion at Cal Poly, there will be significant changes to the curriculum and course numbering system. These changes are designed to streamline the academic experience and ensure that courses are clearly categorized by their academic level and type.
Only approved semester courses will be offered starting Fall 2026. Students should consult advisors to determine which courses to take before or after the transition. For example, some of the three quarter course series have been combined into two course series for semesters. Other courses are simple conversions of their quarter course with very few or no changes to the course. Courses will shift from 3-digit to 4-digit numbers to distinguish semester offerings. So, for example, PHIL 231 on quarters will be PHIL 2231 on semesters.
