The Superintendent, with input from staff members, will prepare salary schedules annually for all non-administrative employee groups. These schedules will be submitted to the Board of Education for approval. (See also Policy 4131 - Extra Duty and Extended Duty Contracts.) Salary recommendations for all administrators will be prepared and submitted to the Board annually. Administrative salaries will be based upon a variety of factors, including educational preparation, years of service within the District and within public education, years of service as an administrator at each administrative level, regional comparisons to similar districts, number of contracted days, administrative responsibilities, and salaries of other District administrators within category -- building and central office. Consideration will be given to administrators' previous salary for all newly hired administrators.
