The Lincoln Public Schools, when accepting federal funds, will seek to allocate District personnel, curriculum materials and instructional supplies among the attendance centers on an equitable basis in compliance with federal laws and regulations. To this extent, the District shall strive to maintain a balance of personnel, curriculum materials, and instructional supplies so that the deviation among attendance centers at an organization level (e.g., elementary) is no greater than 10 percent. Unpredictable changes in student enrollment or personnel assignments that occur after the beginning of a school year shall not be included as a factor in determining comparability of services.
