Subject Area CommitteesSubject Area Committees (SAC): Subject Area Committees consists of K-12 teachers who represent their grade level or department. This group is responsible for reviewing and revising the curriculum for their grade or subject and overseeing the implementation of the curriculum. The process each SAC goes through is extensive, detailed and process-driven. Teachers analyze what is currently being taught in each classroom. Based on national standards and the Iowa Common Core, teachers determine the developmental appropriateness of content and the needs of students after they leave our school system for college or work. A factor in determining content are the Iowa tests given each year determining adequate yearly progress in the areas of math, reading, and science.
