Physical therapist vs physical therapist assistant
According to BLS, physical therapists need a Doctor of Physical Therapy degree and must be licensed in every state, while physical therapist assistants need an associate’s degree from an accredited program and must be licensed or certified in every state. Both kinds of programs are accredited by CAPTE, and both take an NPTE at their own level.

BLS figures are from the physical therapists and physical therapist assistants and aides handbook pages, checked November 10, 2026. On that date, the physical therapists page showed “Last modified date: October 29, 2026”, and the physical therapist assistants and aides page showed “Last modified date: August 27, 2026”. The assistant figures here are BLS’s assistant-only numbers, not the combined assistant-and-aide Quick Facts. See PTA pay and outlook for the combined and aide figures, labeled. APTA wording is from Becoming a Physical Therapist, Becoming a Physical Therapist Assistant, and careers in physical therapy.
How the roles work together, in official words
BLS states: “Physical therapist assistants, sometimes called PTAs, and physical therapist aides work under the direction and supervision of physical therapists.” It also states: “Under the direction and supervision of physical therapists, physical therapist assistants treat patients through exercise, massage, gait and balance training, and other therapeutic interventions. They record patients’ progress and report the results of each treatment to the physical therapist.”
APTA’s becoming-a-PTA page states: “Physical therapist assistants implement components of patient care, obtain data related to the treatment provided, and collaborate with the physical therapist to modify care as necessary.”
Supervision ratios and rules are set by each jurisdiction. Confirm them on the board site through the state and territory directory.
Moving from PTA to PT
CAPTE’s accredited programs page states: “Bridge programs are designed for physical therapist assistants who want to continue their education to become a physical therapist.” CAPTE lists them on its PTA to PT bridge page.
Assistants are not aides
BLS covers physical therapist aides on the same handbook page, but describes a different job: “Physical therapist aides often have tasks that are indirectly related to patient care, such as cleaning and setting up the treatment area, moving patients, and doing clerical duties.” It also states: “States do not require physical therapist aides to be licensed.” This site’s career pages cover the PTA path, not the aide job.
