Teachers assistants help teachers in the classroom by taking attendance, working with students, setting up materials, grading paperwork, and making copies. To become a teacher's assistant requires graduating from an instructional assistant program at a technical college and taking courses that meet college entrance requirements in subjects like biology, chemistry, and literature. Teachers assistants can expect good job opportunities as employment depends on school size and population, with a typical salary range of $16,820 to $33,590 annually depending on location, institution type, training, and education.
