Combining formal instruction, work group activities, and field experience in nonmetropolitan counties, this last of three publications making up a community development training manual deals with extension programming in community development (CD). It is primarily intended for Extension Service personnel who have responsibilities for planning, implementation, and evaluation of Extension community development programs. The first two documents give background information, suggested procedures for conducting inservice training based on the manual, and comprehensive community development training units for agency personnel who provide assistance to local community development efforts. This publication reviews the overall Extension educational programming framework, examines its application to Extension CD programs, and directs a simulation of the Extension programming process through work group development of program proposals for an Extension CD program in the host county. There is a trainer's guide for this instructional unit, an amplified content outline, visuals for overhead projectors, a detailed daily schedule, and seven supporting resource papers which deal with Cooperative Extension Service philosophy of program development, the CD process and Extension CD program development, Extension programming, follow-up on CD projects, and developing the CD program.
