CASE has two levels of teacher trainers called Master Teachers and Lead Teachers. Master Teachers are teacher trainers who have attended a CASE Institute for a specific course, provided instruction to secondary students in that course for at least two years, and conducted a CASE Institute as a Lead Teacher for at least one year. Lead Teachers are teacher trainers who have attended a CASE Institute for a specific course, provided instruction to secondary students in that course for at least one year, and attended a Lead Teacher Orientation Session prior to teaching their first CASE Institute.

Lead Teacher Orientations provide prospective Lead Teacher candidates training related to delivering an CASE Institute. Because CASE Institute sessions reduce 175 days worth of instruction into 80-hours of instruction, CASE Institute trainers must analyze and evaluate each component of the curricula to create a well-balanced and effective CASE Institute. Lead Teachers will understand how to create a scope and sequence and refine delivery skills for teaching to an adult audience.

Once Lead Teachers have successfully completed an orientation they have the potential to be selected by CASE staff to co-teach a CASE Institute session with a Master Teacher.
