Professional development education for teachers is essential to improving teacher retention, program relevance and effectiveness, and the preparation of fully qualified and highly motivated career and technology educators at all career stages (Doerfert, 2011; Lambeth, Elliot, & Joerger, 2008). Furthermore, it is necessary to link industry experts with teachers to improve their competence in teaching curriculum, establishing mechanisms of consultation and support, and to introduce new ideas (Little, 1993). This study sought to evaluate the effectiveness of the Lincoln Electric welding technology workshop, determine if teachers' Performance and Consequence Competence changed, and determine the professional development needs of the participants. The Borich (1980) needs assessment model was used to determine mean weighted discrepancy scores. Findings indicated that the workshop was effective; teachers' Performance Competence and Consequence Competence changed positively after completion of the workshop; and participants were mostly in need of future professional development in the welding technology skill area of Gas Tungsten Arc Welding.
