This booklet is one of five related publications that delineate the program developed by the District of Columbia Public Schools for fulfilling the district's educational mission. The heart of this effort is the design and implementation of a districtwide competency-based curriculum for the prekindergarten level through grade 12, plus the development of attendant organizational structures and planning and evaluation strategies. This particular volume outlines a design for the delivery of educational services that was developed to facilitate the implementation of that curriculum. Emphasis of the booklet is on the different objectives and functions of the delivery system and on the organizational and functional relationships between district personnel that form the framework of the delivery system.
