Gregory,
You bring up an interesting scenario. Similarly, a school may have difficulty finding instructors who meet all the TWC-CSC requirements in career fields that pay very well for those with experience. I suggest caution when submitting a variance in regard to schools located in rural areas or small cities. If a school claims there are limited employment resources in the area, this could call into question why the school is located in that area or why are they offering programs with limited employment opportunities. The CSC Instructor Application (PS-002 page 9) provides an example of a variance request - it is better to focus on why and how the instructor candidate is otherwise qualified to teach, how this assessment was made, as well as what the school will do to ensure the instructor is effective.
