Hi Amy,
From what I have heard from residents and parents the schools in Pebble Beach are excellent. You can probably look up specific scores on greatschools.net. My wife and I homeschool. But Monterey, Pebble Beach, Pacific Grove and Carmel are all known for their good schools.
When we were thinking of moving here another parent (jenndslp) gave me some good advice on the area. You could do a search here and see what her responses were as well. I find the residents very friendly and helpful.
The one thing to consider is that while Pebble Beach is probably the most scenic, although Carmel and Pacific Grove are very nice as well, you are a bit more isolated there. It is a private residential community and there are no real stores to speak of. The median age of residents is above 60 (old money). Hence there are not as many families with children as in PG, Monterey or Carmel. Although there are still some children there. A friend of mine at work has lived there all his life and said he and his wife haven't had a trick or treater in over 20 years.

They buy candy every year just in case.
