The Class of 1957 had 181 graduates, with 41 percent of them attending a four-year college. In 1969, there were 570 grads, with 66 percent going on to college. The 1970s showed the largest enrollments, with the Class of 1977 the largest graduating class in Bethel Park history—790 graduates. In 1988 the graduating class was dramatically smaller—336 grads, with 64 percent going to a four year college after graduation. The 1990s saw a slight increase in enrollment, with graduating classes numbering in the 400s. In 2008, 467 students comprised the graduating class, with 80 percent planning to attend a four year college, 13 percent attending a two year school, six percent attending a business or technical school and one half of one percent entering the military.
