What kind of input are you looking for?
Those 3 schools are all part of the Adams 12 Five Star school district. You can look up the school accountability reports at this link:

All 3 of the schools you mentioned earned a score of "high" on overall academic performance on the state assessments for the 2007-08 year. But of course, the assessments are just one piece of the puzzle.
We recently moved to CO from MI ourselves (I recognize your name from other threads) and we ended up settling in Westminster. Our oldest goes to Cotton Creek. School has only been in session for about 3-4 weeks, but we've personally been very happy with Cotton Creek so far. The neighbors I've had a chance to talk to about school also seem happy there.
If we hadn't ended up with the house that we bought, our Plan B was to buy in Broomfield -- Coyote Ridge boundaries specifically. We had been quite impressed with Coyote Ridge when we researched it. Happy to share my thoughts on what we liked about the school, but what
we found impressive and liked may not be the same thing(s) that YOU are looking for in a school. Hence, it would be helpful to know what kind of input you're looking for.
