Whats the difference between an MPT, MSPT and DPT, and which one should I pursue?

Masters of Physical Therapy, Masters of Science in Physical Therapy, and Doctorate of Physical Therapy are all graduate-level degrees that allow you to practice PT (provided you pass a licensing exam). Most Texas schools offer Masters programs. The APTA has good information about the issues involved with the degree choice, and their vision for all programs in the nation to be at the doctorate level by the year 2020.
