Extension Networks and Dissemination of Horticultural Advancements: Development and Validation of a Professionalization Instrument

Abstract

Horticulture is a vast scientific discipline ranging from ornamentals to consumable food, which is constantly evolving. One of primary goals of horticultural innovation is to improve consistency, and predictability, among products. Extension is one of the primary channels connecting innovations and technologies to growers. However, despite the importance of extension in the dissemination of horticultural advancements, there are no standards for the professionalization of extension networks. Therefore, there is a current gap in the ability to ensure consistency amongst extension providers through professionalization at the network level. The goal of the study was to develop and validate an extension professionalization scale to empirically measure the most critical factors associated with extension professionalization within extension networks. Methodologically, the study extends upon previous research which identified specific capacities associated with extension professionalization at the network level. Specifically, an exploratory factor analysis was undertaken to examine the latent factor structure of the previously identified items. The results of this study identified two primary factors associated with extension professionalization in networks: (a) awareness of the need for extension professionalization, and (b) the operational integration of extension professionalization activities at organizational levels. Although there is existing literature examining professionalization, there are no such instruments specifically developed within an extension context. The present study provides an original and novel tool to prepare more rigorously and consistently trained extension professionals to serve and support the horticulture industry.
