The graduation rate, percentage of students who complete their program within given time, can be a simple and standard measure to rank colleges.
For the graduation rate, 150 percent of the published (normal) time for the program is used to compute. For example, 150 students out of 200 total students have completed their associate degree program, (i.e. 2-years program) in 2 years, additional 30 students have completed in 3 years , then the graduation rate is 90% ( (150 + 30) / 200 * 100).
Fred W Eberle Technical Center has the highest graduation rate (100%) and CT Aero Tech School has the second lowest rate (98%) based on academic year 2019-2020 graduation data.
