While the field of Instructional Design and Technology is growing, finding a job can be difficult (in part because jobs are posted all over the place). It is important to know the right places to look. The following are some of the top job boards to check when looking for a job as a instructional designer, instructional technologist or basically any job related to the field of Instructional Design and Technology (IDT). I recommend searching using key words (e.g., “instructional design” “educational technology” “instructional developer”) as well as searching by position/type or category (if available).
