Workers who are interested in education and who enjoy assisting students do well in this job. Interpreters who know sign language for hearing-impaired students are in demand. Employers need teacher aides to work with students who have physical or learning disabilities. Many aides start as volunteers to gain experience. For a teacher aide to advance to working as a classroom teacher requires a four-year college degree and teacher's certificate.
Some states require that teacher aides be licensed or certified.
Requirements vary by state. Contact your state Department of Education to determine whether a license is required in your state.
