OT vs PT vs SLP Compared
Occupational therapist (OT), physical therapist (PT), and speech-language pathologist (SLP) are the three major rehabilitation professions in U.S. healthcare. All three are master's or doctoral-level professions, all three serve overlapping patient populations, and all three pay reasonably well. But the daily work, training time, scope, and pay differ in ways that matter when choosing among them.
The short version: PT has highest median pay ($99K) with 7-year training to DPT. OT has similar median pay ($97K) with 6-7 year training to MOT/OTD. SLP has lower median pay ($84K) with 6.5-8 year training to master's plus CFY. All three have strong demand growth.
Salary Comparison
BLS data:
- Physical Therapist: Median $99,000, top decile $128,000+
- Occupational Therapist: Median $97,000, top decile $122,000+
- Speech-Language Pathologist: Median $84,000, top decile $128,000+
PT and OT have similar pay; SLP slightly lower. At specialty levels and private practice ownership, all three can reach $150,000-$280,000+ in mature specialty practice.
Training Time
- PT (DPT): 4-year bachelor's + 3-year DPT = 7 years
- OT (MOT/OTD): 4-year bachelor's + 2-3 year master's or 3-year doctoral = 6-7 years
- SLP: 4-year bachelor's + 2-3 year master's + 36-week Clinical Fellowship = 6.5-8 years
Scope of Practice Differences
PT scope: Movement, mobility, gait training, manual therapy, exercise prescription, post-surgical rehab, neurologic recovery. Focus on physical function and movement.
OT scope: Functional independence in daily activities, fine motor skills, sensory integration, adaptive equipment, cognitive rehabilitation. Focus on activities of daily living and participation.
SLP scope: Speech, language, voice, fluency, cognitive-communication, swallowing disorders. Focus on communication and swallowing function.
Cross-Practice Settings
All three professions work in similar settings — schools, hospitals, SNFs, home health, private practice, pediatric clinics. Most rehabilitation departments employ OTs, PTs, and SLPs as integrated rehab teams.
Career Mobility
Cross-mobility between professions is limited. Each requires distinct master's or doctoral training. Within each profession, specialty paths exist (hand therapy CHT works for both OT and PT, with CHT credential supporting cross-discipline work).
Job Outlook
- SLPs: 21% growth (much faster than average)
- OTs: 11% growth
- PTs: 15% growth
SLP has fastest projected growth driven by autism diagnosis growth and aging population. All three professions have strong demand outlook.
Which to Choose
Choose PT if interested in movement, manual therapy, and physical rehabilitation. Highest median pay among the three.
Choose OT if drawn to functional independence work and adaptive skills. Strong specialty options especially hand therapy.
Choose SLP if interested in communicatiocommunication, language, and swallowing disorders. Strongest demand growth.
Education Path Comparison
OT: 4-year bachelor's plus 2-3 year MOT/OTD program plus 6 months fieldwork. Total 6.5-7.5 years post-high school. Total cost $80,000-$300,000+.
PT: 4-year bachelor's plus 3-year DPT (Doctor of Physical Therapy). Total 7 years post-high school. Total cost $80,000-$300,000+.
SLP: 4-year bachelor's plus 2-year master's (MS-SLP) plus Clinical Fellowship Year (CFY). Total 6.5-7 years post-high school. Total cost $60,000-$250,000+.
Pay Comparison Long-Term
OT Year 10: $90,000-$115,000+ for general practice. CHT specialty $110,000-$145,000+.
PT Year 10: $90,000-$120,000+ for general practice. Specialty (sports, orthopedic, neuro) $100,000-$140,000+. PT clinic owners $130,000-$200,000+.
SLP Year 10: $85,000-$110,000+ for general practice. Medical SLP (acute hospital, dysphagia specialty) $95,000-$125,000+. Private practice SLP $90,000-$160,000+.
Daily Work Comparison
OT daily: functional independence focus. Treat clients on ADL (Activities of Daily Living), work readiness, leisure, splinting, adaptive equipment. Balance of clinical evaluation and intervention.
PT daily: movement function focus. Manual therapy, therapeutic exercise prescription, modalities, gait training, ADL related to mobility. Heavy hands-on physical work.
SLP daily: communication and swallowing focus. Articulation therapy, language therapy, fluency therapy, swallow studies, AAC (augmentative communication) systems. Can include video swallow studies (radiology partnership).
Practice Setting Comparison
OT: hospitals, outpatient clinics, schools, SNFs, home health, mental health, pediatric clinics, private practice. Most diverse practice settings.
PT: hospitals, outpatient clinics, sports clinics, SNFs, home health, schools (less common), private practice. Strong outpatient orthopedic concentration.
SLP: schools (largest employer), hospitals, private practice, early intervention, telehealth. School-based heavy concentration.
Career Crossover Potential
Limited crossover between three professions. All require separate degrees. Most rehabilitation professionals stay within their original profession over career. Some OT/PT/SLP combine practice within multidisciplinary clinic but each maintains own credentialing.
Job Market Comparison
OT: BLS 12% growth through 2032. Strong demand from aging population.
PT: BLS 17% growth through 2032. Strong demand. Direct access in most states drives growth.
SLP: BLS 19% growth through 2032 — strongest of three. Aging population, autism awareness, stroke survivors, pediatric speech needs.
