OP here...Oh I totally agree its way too early to think about the application process. I was more interested in learning about the programs that fit the parameters I know are important to us...more or less a starting point. My private school experience growing up with a major part of who I am today, in a good way

And it took finding a culture that was right for my entire family.
Good private schools are tough, competitive and with the right mix of components very rewarding. Just trying to learn about what the DC schools have to offer overall. And good is defined as what makes sense for your child and family.
For what its worth, I love research, so this is more of a learning tool right now.
Thanks again for all the information and insight!!
