Vantaggi
Students are great, office is super supportive, school pays for collab time with other instructors, paid training 4 or more times per year, opportunities to do more than teach (create teaching resources, mentor).
Svantaggi
Because it's a supplemental school, hours are usually part-time. If you don't start at the beginning of the school year, you will usually have the after-school crowd (3 to 7pm or so), but in your second year you'll get lots of day students taking credit classes.
