It’s all about crunching the numbers. Tennessee State University hopes to boost its graduation rate with high achieving students from out of state. A similar initiative is being offered at the University of Tennessee at Martin. They will discount tuition for out of state students next semester by 50 percent if they have at least a 3.0 grade point average. It’s expected that about 500 students will benefit from discounted rates this fall. The cost for tuition and fees are slightly above in state rates so Returning out of state students will automatically receive the discount if they meet the grade requirement. (bg)
