According to Brett McMurphy of ESPN, TCU and Baylor's student-athletes are tied atop the Big 12 with an Academic Progress Rate (APR) of 962, meaning that according to the NCAA, they're the best at learning stuff.
Football APR Big 12: Bay & TCU 962, OU 960, KU 958, WVU 950, KSU 948, TT 941, UT 936, ISU 928, OSU 926— Brett McMurphy (@McMurphyESPN) June 11, 2013
How is an APR score determined? The NCAA explains (from Jason Kirk's article here):
Every Division I sports team calculates its APR each academic year, based on the eligibility, graduation and retention of each scholarship student-athlete. Teams scoring below certain thresholds can face consequences, such as practice restrictions and restrictions on postseason competition. Rates are based on the past four years' performance.
In order for a school to be eligible for 2013-14 postseason play, schools must score above 900 for their multi-year (4 year) APR, or have an APR above 930 for at least two years in a row.
This number will jump for the 2014-15 postseason, and schools will need to have above a 930 for their multi-year APR, or a 940 average the past two years.
TCU and Baylor are both in good shape it would seem, but other conference mates aren't so lucky.
Oklahoma State and Iowa State are both resting below the 930 mark, at 926 and 928, respectively. If those numbers don't reach 930 by the 2014 school year, they would be ineligible for postseason play.
The rest of the conference shakes out as such:
TCU & Baylor - 962
Oklahoma - 960
Kansas - 958
West Virginia - 950
Kansas State - 948
Texas Tech - 941
Texas - 936
Iowa State - 928
Oklahoma State - 926
