Double Degrees

Up to 30 hours of work toward a master of arts or master of divinity degree at Asbury Seminary may be accepted as advanced standing toward a second degree at that level at Asbury Seminary. Up to 30 hours of work toward a theological masters degree earned at another accredited seminary may be accepted as advanced standing toward a master of divinity or a master of arts in counseling degree at Asbury Seminary. Up to 29 hours of work toward a theological masters degree earned at another accredited seminary may be accepted as advanced standing toward any other master of arts degree at Asbury Seminary. Thus it would require at least 30 additional hours to add a master of arts degree to another M.A. or to the M.Div. It would require at least 66 additional hours to add a master of divinity to a master of arts degree. All requirements for each degree must be met.

Movement Between Programs

Students admitted to a degree program in the School of Theology may petition to change degree plans between the various degree programs offered by the Seminary. However, movement between the M.Div. degree program and most of the Seminary’s M.A. programs will usually require substitutions in core requirements in Biblical Studies and Church History.

M.A. students who have already taken BS 501 - 502 Introduction to Biblical Studies 1 - 2, who wish to transfer to the M.Div. program, will be granted advanced standing in NT 520 New Testament Introduction, OT 520 Old Testament Introduction, and Inductive Biblical Studies - 1, but then will be required to take an Inductive Biblical Studies - 2 course as well as a 3-hour independent study crafted by the Area of Biblical Studies. M.Div. students wishing to transfer to an M.A. program should consult with the Chair of the Area of Biblical Studies to determine possible substitutions of core requirements.

M.A. students who have already taken CH 500 Turning Points in Church History, who wish to transfer to the M.Div. program, will be allowed to count CH 500 toward the core requirement of 6 units in Church History, and will be required to take an additional course in church history. This second course may be selected from any course with a CH prefix at the introductory (this is, 500) level. M.Div. students who have already taken CH 501 - 502 Church History 1 - 2, who wish to transfer to an M.A. program, will already have fulfilled the core requirement in Church History for the M.A. program, and may count the additional 3 hours in Church History as elective hours. M.Div. students who have taken only CH 501 or CH 502, who wish to transfer to an M.A. program, should consult with the Chair of the Area of Theology, Philosophy, and Church History to determine how to fulfill their core requirement in Church History.
