A teacher assistant, also known as a teacher’s aide or paraprofessional, is a person who works alongside a certified teacher in a classroom to provide additional support and assistance to students. They may help with classroom management, grading, lesson planning, and individual student needs. Teacher assistants may also work with students who have special needs or disabilities, providing one-on-one support and accommodations. They play an important role in helping teachers create a positive and effective learning environment for their students.
