Community college students who transferred to the state’s four-year online college program before completing their associate’s degree could be eligible to receive their degrees retroactively. The so-called reverse-transfer program will allow Naugatuck Valley Community College to issue associate’s degrees to students who complete at least 15 credits at Naugatuck and continued their course work at the online Charter Oak State College. Naugatuck Valley Community College, with campuses in Waterbury and Danbury, is the first in Connecticut to adopt the program. To be eligible, students would complete at least 45 credits at Charter Oak, for a total of 60 credits, and meet other requirements to obtain an associate’s degree. Other community colleges are expected to follow, and Western Connecticut State University is considering participating in the program.
