Agricultural development has always been the main concern of development agencies throughout the world. The importance of extension service becomes vital especially for the developing countries including Pakistan where majority of labour force is employed in agriculture. An extension service is primarily responsible for the transfer of technology among the target users. It can perform its job effectively if the extension agents are professionally and technically competent. The Agricultural Extension System in Pakistan is under heavy criticism now-a-days for not performing its job effectively. Hence, there is dire need to identify the training needs of the extension personnel working at various levels to prepare a competent work force. Extension Agents must be proficient in a number of professional competencies that includes capabilities; Planning for Agriculture Extension Program, Use of Extension Methods, Communication/Presentation Skills, Supervision and Administration, Evaluation, Skills of Participatory Extension Techniques, Computer Skill/Knowledge, and Public Relation Techniques. Therefore the present study was designed to analyze, identify and prioritize the training needs of extension personnel working in Punjab, Pakistan. All the extension agents especially Agriculture Officers (AOs) constituted the population for this study. A sample size of 212 respondents was selected by using Fitz-Gibbon Table (1987). A simple random sampling technique was used for selection of respondents and face to face interaction technique was used to collect data for analysis. The data were analyzed statistically by using appropriate computer software “Statistical Package for Social Sciences”. It also presents the possessed and required levels of technical and professional competencies and the difference between required and possessed level were calculated through discrepancy value. On the basis of calculated discrepancy value the identified training needs were assessed and prioritized accordingly. The required training areas which receive high discrepancy values were “the computer skills/ knowledge” with DV=2.22, followed by “the communication and presentation skills” with DV=1.929, and followed by “technical competencies” with DV=1.927, which indicates that in these two categories the extension personnel needs training on priority basis for effective and efficient job performance.
