I am not sure which program I should apply to. What are some of the differences between the specialist (Ed.S) and doctoral (Ph.D.) programs?

One of the most important things for you to consider is what you want to do when you finish the program. If you are interested in seeking licensure as a school psychologist within a school system and are committed to becoming an informed consumer of research to guide your practice, the M.Ed./Ed.S. program may be the best professional match for you. The specialist program takes approximately three years to complete, full-time, including coursework, practicum and internship. If you are passionate about conducting original research, interested in assuming leadership roles in higher education (e.g. becoming a faculty member), and/or wish to become license-eligible through the Ohio State Board of Psychology as an independent provider, the M.Ed./Ph.D. program may be the best professional match for you. The doctoral program takes an average of 7 years to complete; includes additional coursework to inform roles in research and leadership; and includes advanced practicum, comprehensive examinations, dissertation, and a doctoral level internship.
