Quarters and Quarter Units


On October 18, 2021, Cal Poly President Jeffrey D. Armstrong announced that the university would be converting to a semester calendar beginning with fall 2025. More information to come.

Cal Poly's academic calendar consists of four quarters - Summer, Fall, Winter, and Spring (for specific dates, see Academic Calendar).

Cal Poly's academic year consists of Fall, Winter and Spring quarters.

The university year includes, and begins with, Summer Quarter.

Each course offered by the University carries a value in quarter units, often referred to simply as units or credits.

To convert semester units to quarter units, multiply the number of semester units by
1.5. For example,
6 semester units X 1.5 = 9 quarter units.

To convert quarter units to semester units, multiply the number of quarter units by .667.  For example,
9 quarter units X .667 = 6.003, which rounds to 6 semester units.
