Tennessee is about to become the first state in the nation to make community college free for all adults. Lawmakers approved legislation Wednesday that will expand the Tennessee Promise program that launched in 2014. It made tuition and fees free for recent high school graduates enrolled in a community college or technical school. Now, adults who don't already have an associate's or bachelor's degree can go for free, too, starting in the 2018 fall semester. Governor Bill Haslam is expected to sign the bill into law. He proposed the legislation in his State of the State address earlier this year. It's a cornerstone of his initiative to increase the number of residents with a college education to 55% by 2025. Last year, less than 39% of residents had gone to college. "If we want to have jobs ready for Tennesseans, we have to make sure that Tennesseans are ready for jobs, and there is no smarter investment than increasing access to high-quality education," Haslam said in a statement. To be eligible, students must have been a state resident for at least a year before applying, maintain a 2.0 GPA, enroll in enough classes to be a part-time student, and complete the Free Application for Federal Student Aid. Expanding the free-tuition program will cost about $10 million. It will be funded by the state's lottery account. More than 33,000 students have benefited from the Tennessee Promise program in its first two years, raising enrollment among first-time freshmen by 30%.
