Results indicated that 4-H youth development personnel wanted higher levels of coordinated efforts between the organizations and to utilize the resources provided by secondary agriculture teachers. Despite the desire of 4-H youth development personnel to participate in interorganizational cooperation, their perceived level of cooperation was lower than that of their desired level.
