They pay a lot
I have worked with around 2-3 other staffing agencies in the past. Nothing is really new to me, but EdTheory is pretty interesting because it feels like a personal experience. Their pay for travelers is very high, and I thought I would not have my current offer topped. Good combination of great pay, pretty good benefits, support, etc. I think they match 401k by a percentage after working a few years.
Solid all around, pleasant surprise
Takes a while to find job in my area
