You start the process to become a licensed chiropractor during your second year of chiropractic school.
That's when you take part I of the national exam.
Part I includes questions about spinal anatomy, physiology, pathology, chemistry, and microbiology.
You can take part II of the exam during your third year of school.
Parts III and IV of the national exam are taken 6 to 9 months after graduation.
Once you pass the national exam, you'll have to contact your state board to see what your next steps are to get your license.
