As formal education became more widely available in the 20th century, teachers' jobs became more complex. The size of classes increased, and a growing educational bureaucracy demanded that more records be kept of students' achievements and classroom activities. Advancements in technology, changes in educational theory, and a great increase in the amount and variety of teaching materials available all contributed to the time required to prepare materials and assess student progress, leaving teachers less time for the teaching for which they had been trained.
To remedy this problem, teacher aides began to be employed to take care of the more routine aspects of running an instructional program. Today, many schools and school districts employ teacher aides, to the great benefit of hardworking teachers and students.
