I would definitely stick to Katy ISD (south of I-10). Griffin is a new school. I know several people with children there. I've heard no complaints about the school itself. The only problem with moving anywhere west of 99 is that the area is growing SO rapidly you will surely be rezoned at some point unless you live in the immediate area of the school. My good friend lives in Seven Meadows and her children and been zoned to Kilpatrick, then to Griffin when it opened, and in a couple of years when the elementary in Seven Meadows opens, they will move again! Just be aware of that possibility. Of the elementary schools west, I would definitely try to be zoned to Rylander, Griffin, or or Woodcreek (opening this coming year).
