This study investigated perceptions of resource development committee representatives regarding organizational and program aspects of the Ohio Cooperative Extension Service, and factors associated with the perceptions. Four rating systems were used to measure dimensions of 95 statements on intensity of involvement, knowledge of the organization, the importance of various aspects, and the performance by the Cooperative Extension Service as a educational agency. Respondents to the mailed questionnaire were 165 committee members and 119 consultants (a 53.1% return). These were among the findings: (1) the majority of the respondents were associated with farming and agricultural industrial occupations and were interested in education for farming, homemaking, and youth work; (2) they viewed as most important those extension goals, functions, and program areas relating to farm family living; (3) intensity of one's own involvement with the Extension Service was the main determinant of perception; (4) the Cooperative Extension Service was seen as basically a rural oriented, immediate problem centered educational program.
