The continuing shortage of agricultural education instructors has been documented across the state and nation. Secondary instructor retention may help reduce the shortage and position changes each year. Identifying the challenges facing beginning teachers as perceived by beginning teachers, veteran teachers, and building administrators can help identify the professional development and mentoring needs to assist in teacher retention. Establishing consensus among the target groups through this Delphi study will allow Idaho Team Ag Ed to be specific and purposeful in long term professional development planning. Through this study, 21 professional development areas were agreed upon in three areas: Teacher Skills and Knowledge (8); Personal Skills and Professional Development (6); and Program Area Concerns (7). Volume of work was the area of highest concern (n = 92, 90.11%) followed by classroom management skills and teaching experience (n = 81, 89.01%) and 79 of the 91 respondents (86.81%) agreed that finding alternative funding sources was an area of concern followed closely by overall program funding (n = 79 of 90 responses, 87.78%). The consensus supported previous research across the country and will provide a guide for targeted professional development, mentorship, and long-term retention for beginning teachers (0-5 years' experience) in Idaho.
