The Kansas State High School Activities Association has changed its method of determining the classes in all sports other than football and it may have affected Pittsburg.
In the past, the six classes were determined by a count of students in grades 10-12. Beginning year, the KSHSAA is counting students in grades 9-12.
Pittsburg, the largest school in the Southeast Kansas League, has a count of 717 students. That drops it from Class 5A to make it the largest school in 4A.
Each of the other SEK schools remain in 4A. Independence is the second-largest with 570 students followed by Chanute at 565, Fort Scott 555, Labette County 544, Parsons 393, Iola 386 and Columbus 319.
Iola and Columbus are each in their last season as SEK schools.
Uniontown, Northeast and Pleasanton all changed classes as far as Three Rivers League schools go. Northeast (155) and Uniontown (138) drop down from 3A while Pleasanton (110) moves up from 1A. Oswego (145), Jayhawk-Linn (144) and Marmaton Valley (107) are also 2A. St. Paul (84), Chetopa (67), Crest (60) and Altoona-Midway remain Class 1A schools.
