Doctor of Philosophy in Rehabilitation Science (PhD RS)

Program Description

Rehabilitation science is a broad and growing field that improves the treatment, care, and lives of people with potentially disabling health conditions. It includes researchers, educators, and professionals who advance, teach and apply knowledge to care for people with health needs.

The Ph.D. in Rehabilitation Science program educates students to become innovative educators, researchers, and leaders in rehabilitation science. Our graduates become scholars in higher education and other settings who advance and distribute knowledge to enrich the lives of people with communication and movement disorders. Our program emphasizes the athletic training, audiology, occupational therapy, physical therapy, and speech-language pathology rehabilitation domains. We foster interprofessional and interdisciplinary collaboration to advance treatment and enablement theories that will improve rehabilitation practice. We welcome qualified students from related clinical and non-clinical backgrounds who are passionate about rehabilitation science, learning, teaching, and research.

The Ph.D. RS program offers Communication Sciences and Disorders (CSD) and Movement Sciences and Disorders (MSD) concentrations. The program's face-to-face curriculum includes several distance course options. Faculty from seven programs and two departments educate Ph.D. students in rehabilitation science foundations, professional development, teaching methods and practices, research design and statistics, technical writing, and research. Students develop an individualized concentration plan, including seminars, research methods, and discipline-specific courses. They take electives from other programs, departments, and schools at TTUHSC and TTU. Students choose academic and research emphases based on their interests and career goals. All students complete a research project, comprehensive qualifying examination, and doctoral dissertation. Graduation requires 86 semester credit hours over typically four years, with up to 24 graduate-level transfer hours possible. Ph.D. students may enroll full or part-time, and teaching and research assistantships are available.

Program Admission

Applications for admission are due by February 1 for the Summer semester, March 15 for the Fall semester, and October 15 for the Spring semester.

Ph.D. RS program admission is competitive and based on the applicant's academic record, professional experiences, goals, interests, optional GRE scores, and potential to contribute substantively to rehabilitation science. The admission requirements are

  • graduate degree in rehabilitation science or a related area
  • official transcripts reflecting all coursework, an earned graduate degree, and a minimum GPA of 3.0 out of 4.0 in the last 60 semester credit hours
  • GRE scores (verbal, quantitative, writing) are optional but recommended
  • three letters of recommendation
  • application essay describing the applicant's research interests, career goals, and relevant experiences
  • sample of research writing
  • résumé or curriculum vitae

The admissions committee will interview qualified applicants before making an admission decision.

Ph.D. RS Curriculum

The Ph.D. RS program requires 86 semester credit hours, including up to 24 hours from graduate-level transfer courses. All students take a 44-hour core curriculum and 42-hour concentration in Communication Sciences & Disorders or Movement Sciences & Disorders.
