NOTE: Elementary-level teachers either instruct any of grades prekindergarten through 5th grade and have a main teaching assignment of early childhood/prekindergarten, elementary education, special education (in self-contained classrooms), or elementary enrichment; orr teach most or all of their classes in any of grades K-6. Secondary-level teachers instruct any of grades 7-12 but usually no grade lower than 5th. They also teach more of grades 7-12 than lower grade levels. Teachers of only ungraded classes are considered elementary-level teachers if their main assignment is early childhood/prekindergarten or elementary, or they teach either special education in a self-contained classroom or an elementary enrichment class. All other techers with ungraded classes are classified as secondary level.
