NASHVILLE — An often overlooked but important component of TN Promise is the required community service hours each student must complete prior to the start of each college semester. The idea is to ensure students are cultivating a culture of giving back to their communities. It is also an opportunity for students to explore possible career paths. Since tnAchieves, the precursor to TN Promise, launched in 2008, our students have given back more than 1.5 million community service hours.
