Purpose: The purpose was to analyze perceptions of knowledge management capacity in extension networks using an exploratory factor analysis approach. Design/methodology/approach: The knowledge management content domain was analyzed for content validity, response process validity, internal structure validity, and consequential validity. A pilot version of an instrument was administered to extension network members (n = 122) associated with the Global Forum for Rural Advisory Services. Exploratory factor analysis (EFA) and measures of correlation and reliability were performed to determine the structure and internal consistency of the scale. Findings: The observed structure was similar to the hypothesized structure. EFA indicates further factor analyses should be performed on the aggregate scale and proposed subscales. Practical Implications: The resulting scale has the potential to serve as the basis for a reliable instrument for establishing perceptions of knowledge management capacity, supplementing needs assessment strategies, and informing organizational practices and policy which maximize these capacities in extension services. Theoretical Implications: The resulting scale advances the activity theory framework by conceptualizing dimensions of knowledge management that facilitate development via social interaction. Originality/Value: While various studies have been conducted to analyze the knowledge management capacities of international extension networks, the current study introduces preliminary results of an instrument to discretely quantify perceptions of knowledge management capacity in extension services.
