Concerns of teachers must be identified to provide quality teacher education programs and professional development. The theoretical framework of this study was the Teacher Career Cycle (Fessler & Christensen, 1992). The theory explains that as teachers move through the cycle, their characteristics and professional needs change. The purpose of this study was to identify the concerns of Illinois agriculture teachers of different experience levels. A multi-part instrument of demographic information, two teacher concern statements, and a Likert-type scale of concerns was administered. The sample was divided into three experience groups: early career, mid-career, and late career. The results indicate that certain concerns do change with the level of experience and that mid-career teachers in this sample have the most concerns. We recommend that these results be shared with the Illinois Association of Vocational Agriculture Teachers, universities, state agricultural education staff, and other stakeholders. Those leading professional development should consider years of experience when planning for workshops. Professional development topics on student motivation, funding for supplies, and student safety should be explored.
