RMT stands for Registered Massage Therapist and is a common way for states to refer to legal practitioners of massage. CMT is the same thing, just meaning Certified Massage Therapist. MTI stands for Massage Therapy Instructor, and generally indicates a higher level of education, as an MTI therapist can also train others to become therapists. NCETMB is a test administered by a national organization and accepted by most states, and any therapist who has passed this test can be considered well-educated. In addition, you may see many credentials listed by therapists on their websites which relate specifically to the style of massage they practice. LBMT stands for Licensed Massage and Bodywork Therapist and is often followed by the license number (i.e. LMBT #471).
