If you go to Missouri Southern State University in Joplin, you might be seeing your tuition rates go up. The Board of Governors approved a 9.3% increase at their meeting Thursday. Undergrads using in-state or the Lion Pride discount now will pay $242.96 per credit hour instead of $222.24. The out-of-state tuition rate is now $485.92 per credit hour. These will take effect for the upcoming fall semester.
