In the past 12 weeks of our series "Indiana - By Degrees," reporter Diane Willis has explored the challenges facing Indiana and the innovations it's producing in higher education. This final segment on innovations looks at how one city--Louisville, Kentucky--and the state of Tennessee have both recently undertaken landmark reform efforts to increase college graduation rates. For both, economic competition was a driver. So was increasing the quality of life for their citizens - and creating a change toward a more college-going culture or attitude among residents. Indiana's Commission for Higher Education has set a goal of producing at least 6,000 more high-quality degrees and credentials each year through 2025 to keep pace with the world. That's also Lumina's Big Goal-and it has guided both Louisville and Tennessee's efforts. (www.luminafoundation.org) So how did Louisville and Tennessee start their reforms? What did they focus on first? And how are doing, approximately one year later?
