My 6 year old goes to Sterling Classical School in Leander. They have a preschool that started this year, and also Kinder. I like that they have small class sizes. This is my daughter's second year, and she loves the school and started reading at 5.5, loves to read. The program is 2 days a week, and the teacher sends home lesson plans for 2 days a week (university model, classical school). There is an informational meeting coming up in November, but you might be able to tour any time. The website is sterlingclassicalschool.com and the calendar is on the home page. There is also lots of info about the school's philosophy. Several of the parents there also recommend First Foundations Preschool.
