I do not know of a formal training program to become an apologist, although some universities do offer apologetics as a single course in a theology curriculum. Even so, theoretical apologetics is not all that helpful to a professional apologist. The people with whom an apologist ordinarily deals are not terribly interested in an explanation of Aquinas’s five proofs for God. They are much more interested in whether they can go to a particular wedding next weekend, or with whether they need an annulment in order to remarry. Practical apologetics is usually self-taught, while theoretical apologetics is likely what you’ll find offered in a college course.
Many of the professional apologists either have degrees in associated fields (e.g., theology, ministry), or are entirely self-educated. For more information, see the links below.
