The deadline for high school seniors to register for two years of free tuition at a community college or technical school is Saturday. Administrators with the Tennessee Promise program said they still need thousands of volunteers to mentor those studentOn its 10th birthday, the Tennessee Lottery is celebrating the fact that more than $3 billion have been raised for college tuition. So far, more than 46,000 high school seniors have already signed up for the Tennessee Promise program. “We knew that parents and students would respond to the governor’s vision,” said Mike Krause with Tennessee Promise. “Forty-six-thousand is an exciting number. We’re the only state in the nation giving our students this kind of opportunity, and students are taking advantage of it.” Part of the program requires that all of those students be paired with a mentor. In the next five days, 2,000 more volunteers need to sign up.
