Many people asked the Warrens if they can get a list of accredited universities and colleges that offer parapsychology, or related courses to become a demonologist.
With regard to the many questions concerning the study of parapsychology and on becoming a professional demonologist the Warrens gave this respond. With respect to academic programs in Parapsychology, this area is actually a sub-field of Psychology, and to study it thoroughly, an understanding of its location in the bigger picture of Psychology is necessary. So, the Warrens believes that your college choice decision must be driven by your preferences for institutional size, geographical location, price, faculty research interests, and institutional prestige. Since Parapsychology is often viewed with much skepticism in academic circles, the more legitimate the institution and academic program, the better off you will be.
Please also remember that the Warrens were among very few professional Demonologists, and in fact practiced their profession free of charge to the public–it is through their books and speaking engagements that they earned their living, not by charging for investigations. You may want to keep this in mind as you think about becoming a paranormal investigator as a career choice.
