Marietta College's reported four-year graduation rate is 49%, and its six-year rate is 61%. These are cohort measures: they follow specified groups of entering students over time, rather than describing the share of all current students who will graduate.
The gap between the two rates shows that some students completed after the traditional four-year period. The reported first-year retention rate is 69%, measuring the share of the relevant entering group that returned the following fall. Retention and graduation rates answer different questions, and neither explains why an individual student leaves, stays, or takes longer to finish.
Transfer students, part-time students, and students entering graduate programs may not be represented in the standard first-time, full-time undergraduate graduation cohort. Applicants should consider these institution-wide figures alongside requirements in their intended major, especially if a change of major or required course sequence could extend their timetable.
The available College Scorecard field-of-study figure for Marietta College reports $76,751 in earnings for petroleum engineering measured one year after completion. It is a field-specific outcome for the students included in that federal measure, not a salary offered to every petroleum engineering graduate or a college-wide earnings figure.
Scorecard field-of-study earnings reflect graduates with measurable earnings in the underlying data and can be affected by cohort size, employment location, further study, and the types of jobs graduates take. The figure does not subtract student debt or living costs. A prospective student should therefore compare it with program cost, likely borrowing, career interests, and longer-term employment information rather than use it as a promised starting salary.
