Officials with the Kentucky Community and Technical College System are reminding returning students in its 16 institutions that they will not see a tuition increase in the 2011-12 academic year.Those students must have enrolled during the fall 2010 or spring 2011 semesters to be eligible for the guaranteed tuition rate of $130 per credit hour.The rate was approved by KCTCS regents last year. Tuition rates for the 2011-12 academic year for students not under the plan have not been set. They’ll likely be decided at the regents meeting on June 17.
