Additional duties usually performed by the Instructional Assistant II and Instructional Assistant III are identified on the back. Instructional Assistant I Under general supervision, assists a teacher or other certificated employee in providing instruction to individual students and performs miscellaneous related duties. Instructional Assistant II This level is assigned to an education program where students have behavioral, physical, language or learning handicaps. There is usually a wide range of ages and ability levels. Instructional Assistant III This level is assigned to an education program where there is a group of students designated as an emotionally disturbed (ED) class or an autistic class, or is a class consisting of students who have been expelled, suspended or placed by the court system.
