Serves as a helper to a teacher giving instruction to students. They assist the teacher in being a more effective educator. The teacher's assistant helps the teacher practically organize a lesson to be taught. They often tend to the practical details or set up for a lesson and cleanup the classroom after the lesson. Teacher's assistants can be found tutoring. They are also often found in informal learning environments of instruction, [eg] arts, crafts and motor skills development. Teacher's assistants permit the teacher to focus attention on the students and the lesson itself, without the distraction of practical preparation. Students have better access to personal attention when one or more teacher's assistants are available to them. Further, teachers who have learned their art by being teacher's assistants themselves, have more experience than other teachers.
