The NCAA has stripped California Polytechnic State University (Cal Poly) of wins over three-plus seasons and put the school on two years of probation over violations involving stipends for textbooks given to student-athletes.

The case appeared in the NCAA violations database as of April 18. The NCAA reports that Cal Poly “did not monitor its book scholarship program to ensure the administration of stipends followed NCAA rules.” The NCAA report says that the university provided scholarship stipends to student-athletes to cover the cost of books, but that the $800 stipend ultimately exceeded the actual cost of books by a significant amount, and that the stipends put 30 student-athletes over their financial aid limits.

The report says the school gave the $800 stipends to 265 athletes across 18 spots. The report says that among 72 student athletes, the stipends exceeded the actual cost of books by $16,180. That’s more than $220 extra per student-athlete.

The violations occurred from the 2012-2013 academic year through the 2015 fall quarter, according to the NCAA’s report, which you can read here.

The NCAA lists 19 “involved sports,” including both men’s and women’s swimming & diving. That means any swimming & diving wins between fall 2012 and fall 2015 involving a student-athlete who was given the excessive scholarship stipend will be vacated, including conference and NCAA finishes.
