The District participates in the Missouri Career Development and Teacher Excellence Plan, otherwise known as "Career Ladders." The Career Ladders program is a voluntary program in which the district participates. The “Program” provides a salary supplement for certificated employees including classroom teachers, librarians, counselors, psychological examiners, parents as teachers, educators, school psychologists and speech pathologists. Certificated staff become eligible to apply for participation after two years of public-school teaching in Missouri. In exchange for a salary supplement, participating staff provide additional education services for which they are not presently compensated, all as detailed in Regulation 4515.
