This study aimed to measure agricultural extension service quality in Nubaria region by measuring extension employees' perceptions of the total quality scale components, and farmers' perceptions of service quality scale components. The study was conducted on 20 extension personnel or 76.9% of the total number of extension personnel in Nubaria region (26 Personnel), and 159 farmers randomly selected from two villages in Nubaria region. Data were collected by questionnaire during October 2015. Frequencies, percentages and mean scores were used for data presentation. The results showed that although scores for extension employees' perceptions of the total quality are above average levels for all the twelve components of the total quality scale (75.8% of the total score), this didn't produce an effect upon farmers' perceptions of service quality, as scores for farmers' perceptions of the service quality were below average levels for all the five components of the service quality scale (45.9% of the total score). This indicates a clear gap between the two views of extension employees and farmers about agricultural extension service quality in Nubaria region. Extension employees in Nubaria region need to work hard to close this obvious gap to increase farmers' satisfaction through planning and implementing their extension programs and activities on the basis of farmers' perceptions and needs.
