A teacher's aide may be responsible for a number of duties but primarily help school teachers and staff. Teacher aides are paraprofessionals, meaning that they are not licensed or certified teachers, but work with students under the supervision of a teacher. At times, a teacher's aide will work with academically struggling students to help them improve. In New Jersey, a person should hold an associate's degree to become a teacher's aide. With no prior experience, a New Jersey teacher's aide can receive on-the-job training.
