Chiropractors have to endure an intensive multiyear program similar to other healthcare practitioners in order to get their license to practice. It starts by earning an undergraduate degree, or a 3 year minimum of undergraduate studies with an emphasis in sciences. They then enroll in an accredited Chiropractic school where they spend 3.5 years with more than 4,200 hours of class and lab work where they are immersed in all things related to the anatomy and physiology of the human body, adjusting techniques, and more. Along with this, they need to complete an internship where they focus on adjusting and caring for patients prior to graduating. After graduation, there are 5 national board examinations that must be passed in order to earn their right to practice chiropractic.
