These teacher's aides get great hands-on experience working with students with physical, learning or behavioral challenges. But the stress levels can run high.
Since many aides come to the classroom with little experience, they end up learning on the job, said George Giuliani, executive director of the National Association of Special Education Teachers. And sometimes their working relationship with the teacher -- who is effectively their boss -- can be strained.
"[Aides] work under direct supervision of teachers and they may have a different sense of what their roles are," said Giuliani.
Most find it very rewarding, however, he said, although the monetary rewards tend to be very low. Median pay is less than $25,000 a year.
A CNNMoney analysis of Census data shows these jobs -- which have roughly the same amount of men and women workers -- have little disparity in salaries.
