I recommend Harbour Oaks Montessori in Grayson. I reside in Lawrenceville and my son has been there 2 years and the results/student teacher ratio/& facilities are unparralled from the homework we did two years ago when he enrolled. Definitely recommend an accredited Montessori and shop them vigorously! Expect roughly $590-$675/mo. with discounts if you pay in full or have multiple children. 8:30-3:00 hours and more $$$ for extended stays. Outside of Montessori Schools, I've heard tons of good parent reviews from The Goddard School.

Seb, our daughter attended The Goddard School and was well prepared for first grade.
