Three proof points you can see and verify.
A familiar route matters. What your child finds at the end of it matters more.
Since 1997, in Chantilly
Longevity is concrete here. The school began in 1997, and its address is 3411 Lees Corner Rd in Chantilly. You can locate both the date and the campus.
A 3:1 Toddler ratio
For the youngest children, our Toddler program keeps a 3:1 student-teacher ratio, giving adults room to support language, movement, practical tasks, and hard morning transitions.
Independence with evidence
On a visit, watch one child carry the ten cubes of the pink tower across the room, build it largest to smallest, take it apart, and set it back on the shelf for the next person. Independence is not a promise here. It is something you watch happen.
Programs for the commute
One Chantilly campus can cover the working day.
The school serves ages 18 months to 12 years through Toddler, Early Childhood, Kindergarten, Elementary, & Enrichment.
Before-care begins at 7:30 a.m., and after-care continues until 6:00 p.m. Those hours give commuters room for an early Route 50 start, an afternoon meeting, or siblings with different classroom schedules. The aim is a single, dependable campus rhythm around the Montessori day.
Program fit still starts with the child. A toddler works on dressing frames, pouring, and carrying a tray without spilling. An Early Childhood child traces sandpaper letters and builds words with the moveable alphabet before a pencil is ever required. A Kindergarten child often anchors the room as its oldest, most capable member. An Elementary student moves into research, long division with the stamp game, and projects that run for several days. Families can review the full sequence on the programs page, see how a morning unfolds in a day in the life, and find extended-day options under Enrichment.
