In fall, 1988, the Association for Supervision and Curriculum Development (ASCD) in Alexandria, Virginia selected 12 districts to comprise an Early Childhood Consortium. Consortium members attended two meetings a year for 3 years; received assistance in such areas as child-centered instruction and developmental curricula; planned an exemplary early childhood program for their district; and evaluated outcomes. Section 1 of this third-year report explains the consortium's purpose and goals, the school district selection process, and issues considered. Section 2 describes the six consortium meetings. After a discussion of the design of assessment tools, section 3 summarizes lessons learned about assessment, change, developmentally appropriate programs, early childhood advocacy, full- versus half-day kindergarten, the ways in which young children learn, multi-age grouping, and staff development. Finally, section 4 presents reports from the consortium members, who are employees of school districts in: (1) Aspen, Colorado; (2) Elmira, New York; (3) High Point, North Carolina; (4) Jackson, Mississippi; (5) Lincolnwood, Illinois; (6) Muscatine, Iowa; (7) Portland, Oregon (2 districts); (8) Redwood City, California; (9) Waukesha, Wisconsin; (10) South Brunswick, New Jersey; and (11) Phoenix, Arizona. The consortium application form, the form by means of which districts agreed to participate in the consortium, and a list of the school district addresses are appended. (AC)
