Great student base to work with, and all you have to do is conduct your sessions and document progress. They provide excellent course and practice materials
Cons
None that I can think of. Best job of this type that I have had
Casual office environment, Opportunities to work on projects outside of your job description. Downtown Boston is a nice neighborhood to walk around in during lunch break.
Cons
No mentor program to learn from others. In the office 5 days a week, no parking, so you must live near a public transit system and commute via public transit. There is little to no flexibility on work-from-home options.
