Factors contributing to successful extension programs in American Indian communities are presented in this paper. Implications of the professional person's attitude toward Indian people are discussed, and concepts of program development as their application related to Indian communities are explored. Community involvement in program planning is emphasized as the primary prerequisite to developing successful programs. Other considerations include (1) allowing local Indian leadership to function to legitimize the program; (2) knowledge of past programs which are related to the projected program; (3) the time element in relation to employment, climate, and other factors which might affect program participation; and (4) the level of knowledge and background of experiences of program participants.
