GreatSchools Rating
Parent Rating Average
I would pick Ellis over Stratford, Challenger, Cherry Chase, or any of the available options for lotteries or private. First, the facilities are beautiful and functional, as you may know they're brand new. Second, the teachers are tenured, experienced, and truly care about each kid. Third, the community is vibrant. Not just spirit days, but parental involvement that raises the bar. I love Ellis and my kid has been thriving there, compared to Stratford for Pre-k.
