Agricultural sciences teachers instruct students in agricultural science by planning and teaching lessons, giving lectures, assigning and assessing coursework and exams, and giving practical exercises. They work in office and classroom settings at high schools, colleges, and universities. Their working hours vary depending on their course schedule and course load. To qualify to teach agricultural science at the college or graduate level, you'll need to hold a terminal degree (in this case, a PhD). For those without a terminal degree, teaching assistant or adjunct positions may be available. An agricultural sciences teacher should be able to explain complex concepts and their practical applications to novices.
Job openings for agricultural sciences teachers can be found on the career sites of educational institutions that have an agriculture program, which are typically located in rural areas. Vacancies can also be found through typical channels like online job boards such as Idealist.org and Indeed.
The interview will focus on your ability to teach. You'll be expected to demonstrate both technical knowledge about agricultural science and pedagogical methods. You'll be asked about the kinds of methods you use to break down complex concepts. Depending on the institution, you may also be asked about your research interests to see if your goals are aligned with theirs.
To prepare for an interview for agricultural sciences teachers, come up with a five minute sample in which you teach a concept in agricultural science. Perform this teaching sample for a friend or family member who knows very little about the topic, and then test them for understanding by asking them to explain the concept back to you. You needn't be perfect: the goal is to get practical experience delivering a lesson so that pedagogy is fresh in your mind. In addition to that, research the school and identify the mission of the department you're applying for. Then think about your career goals and research interests and see how they might fit in.
