Pros

The schools and students that should not use agencies!

Cons

Poor poor communication, the employees are unprofessional, work behind a keyboard while the subs are the only ones that actually work. Management is Unavailable, horrible customer service and communication, they hire anyone off of the streets to work with children, Alarming! They have no clue who the people that they are sending into the schools to work with children
