In schools across the country, teacher assistants—also called paraprofessional educators—are an integral part of classroom culture. Teacher assistants provide help to both teachers and students in a variety of ways. For example, a teacher assistant performs simple administrative tasks, like filing paperwork or putting up bulletin board displays, so that the classroom teacher can focus on planning lessons and grading student work. During classroom instruction, a teacher assistant will circulate the classroom and provide help to students who are off-task or confused. At times, a teacher assistant may be asked to lead a small group of students in extra practice on a given topic.
