@Grace T., as I understand the "goal" US Soccer wants better educated coaches at the Rec and Club levels and has recognized that the E License was too easy to get (heck I have an E). The E is fine for U12 and under, and probably just as good for U14 Flight 3/Bronze, but once you hit the Flight 1+ and olders, the coach really should have a D, which requires that coach demonstrate a comprehensive understanding of how to run a training session, make corrections, etc.
If soccer is going to grow in popularity then we are going to need 1,000's more coaches and referees. The new grassroots licensing system allows new coaches to build that knowledge and its a major overhaul of the current system, so I have a wait and see attitude and look forward to checking it out.
