I'm trying to dig deep in the recesses of my memory to our classes based on DNA. It was dry to say the least. As I recall (and I may be off track), the number of kids is based on square footage. Each child requires a specific number of square feet each. So your measurements for each room and for the play grounds I would imagine would be divided by the requirement for each child - the resulting number would be the number of children you're allowed per room and facility. Then you'd hire staff based on that number and based on enrolment. That's my memory of it, but like I said, that's a long time ago! I'm not sure about window space, etc. There are about a billion hoops to jump through for DNA. It's very, very precise and finicky. Our final exam was to go into a daycare centre that had been 'altered' and we had to create a new daycare from top to bottom. It took 4 days, no sleep and constant work in a team of 3. It's a very, very seriously huge undertaking (and we had an unlimited imaginary budget). Be very careful of your playground equipment as well. We also had to critique various public playgrounds....none of them were up to code. Very strict.

I'd look online maybe for DNA in layman's terms or maybe ask a daycare director if you could have a little time with her to go over it. Good luck!
