Private Kindergarten for 4 year-old FFX Co

[LBCMom]

My daughter will be 4 in January, and I don't think another year in preschool will be a benefit. She knows all her letters, numbers, colors, etc...I'd like to consider private K that accepts 4 year-old since it looks like Fairfax County won't let kids test in early. Anyone have any recommendations for good private schools that offer this?
