Steps to Earn Your Physical Therapist Assistant Certification 

To become certified, you must complete a series of educational and licensing requirements. 

  • Enroll in a CAPTE-accredited PTA program¹ 
  • Complete required coursework and clinical training 
  • Pass the NPTE for PTAs² 
  • Apply for state licensure³ 

Each step builds the foundation needed to begin working as a licensed PTA. 

Step 1: Graduate from a CAPTE-Accredited PTA Program 

Your first step toward physical therapist assistant certification is earning an associate degree from a program accredited by the Commission on Accreditation in Physical Therapy Education (CAPTE).¹ 

Accreditation ensures the program meets national academic and clinical standards. Most PTA associate degree programs can be completed in approximately two years of full-time study.¹ 

Programs combine classroom instruction, laboratory practice, and supervised clinical education. 

Coursework typically includes: 

  • Anatomy and physiology 
  • Kinesiology 
  • Therapeutic exercise techniques 
  • Patient care procedures 
  • Professional ethics 

Choosing a structured, CAPTE-accredited program—such as Stanbridge University’s Associate of Science in Physical Therapist Assistant program—can help prepare students for licensure and workforce entry. 

Step 2: Pass the National Physical Therapy Exam (NPTE) 

After graduating from an accredited program, you must pass the NPTE for PTAs.² The exam is administered by the Federation of State Boards of Physical Therapy (FSBPT). 

The NPTE evaluates entry-level knowledge and ensures candidates are prepared to practice safely and effectively.² Passing the exam is required in all 50 states. 

Step 3: Apply for State Licensure 

Once you pass the NPTE, you must apply for licensure in the state where you plan to work.³ Each state has its own physical therapy board with specific application requirements. 

Licensure requirements may include: 

  • Submission of official transcripts 
  • Background check 
  • Jurisprudence or law exam (in some states)³ 
  • Application fees

State Licensing and Continuing Education 

Licensure is granted at the state level, so requirements may vary slightly depending on location. However, all states require graduation from a CAPTE-accredited program and passage of the NPTE.¹² 

To maintain a physical therapist assistant certification, most states require continuing education credits.³ These requirements help PTAs stay current with clinical advancements and best practices in patient care. 

License renewal periods typically occur every one to two years.³ 

How to Choose the Right PTA Program 

Selecting the right program plays a critical role in completing your physical therapist assistant certification successfully. When comparing schools, consider: 

  • CAPTE accreditation 
  • Clinical training opportunities 
  • NPTE preparation support 
  • Program completion timeline 
  • Student support services 
  • Location and learning format 

A program that integrates classroom instruction with hands-on clinical training can support exam preparation and readiness for state licensure.
