I think that if you start with the structure, milestones and curriculum approach that will give you a feel right away. Then that becomes a fact that you can compare against and forms the basis for your arguments to advance.
When we looked at day cares only one said they would advance Mr W once he had hit all the milestones for that "age group." They brought it up once they saw what he was doing with the toys and stuff in the room. The fact that they noticed him was a big plus as well.
Most places we looked at did not have milestones and just did age grouping.
