During your in-person CPR certification class, your instructor is responsible for facilitating learning of all of the students in the classroom. He or she may lecture, show videos, answer questions, and provide hands-on demonstrations. During your hands-on portion of the class where you get to practice your skills on an actual manikin, the instructor will watch your form and technique, and provide feedback for you to improve. If you have questions or get stuck on any point of the material, your instructor is there to help explain the information in different ways to make sure you understand the course curriculum. Lastly, your instructor will administer your exam at the end of the class. Depending on the program, your instructor may also be responsible for grading your exam.
