They have various responsibilities, which vary depending on the school they are working in. The role generally includes helping students with their reading, writing, assisting teachers in lesson planning, and helping individuals who need specialist assistance. There are many other aspects of the role that depend on multiple factors, such as the school's specific needs, location, and student population.
