DOD's fellowship and training-with-industry programs comprise a few of the several vehicles DOD uses to provide training and education to its military officers to develop and advance their careers while in the military. Officers have educational opportunities throughout their careers, both within and outside of the military educational system. These include attendance at intermediate- and senior-level military schools, as well as participation in graduate programs to obtain advanced degrees. Fellowship and training-with-industry programs constitute another type of professional development that officers may receive in addition to or in lieu of attendance at a military school.
