Who makes more money an occupational therapist assistant or a physical therapist assistant?

yes. much more. OT - need master's degree. PT assistant - associates degree. more school = more $$

not true the COTA ( certified occupational therapy assistant) and the PTA (physical therapist assistant ) make about the same ... both can have a assoc or BS degrees: varies by state ( some PTA's are licenced- eg PTA's in MICH.) PT & OT pay varies by the way either use their skills and if employed by same employer at same job level pay may well be the same . Opportunities to enhance the pay check occur in all professions
