The Girls DA Developmental Player and high school rules have not changed since they came out with the DA, the only significant change has been the addition of a new age group.

FAQ's and linked rules for information.
Some DA clubs are saying different creative things to get players confortabl with joining the DA or their DPL teams but, to US Soccer's credit, their position, while a bit arrogant, has been pretty consistent.
