Why MSOFx
Small enough to notice. Established enough to know.
The strongest case for a school is not a superlative. It is a set of facts a family can verify and a classroom experience they can observe.

Since 1997
Continuity you can ask about.
MSOFx has served Chantilly families since 1997. Longevity gives prospective parents useful questions: what has stayed consistent, what has improved, which families returned with siblings, and how the school has protected its Montessori practice over time.

About 130 children
A community that remains legible.
At this scale, adults can know names, siblings, routines, and the small changes that signal growth or struggle. The school can remain personal without becoming informal about expectations.
One path
From first independence to elementary research.
A child can begin at 18 months and continue through age 12. The rooms change, the questions grow, and responsibility expands, while the underlying relationship between child, guide, environment, and purposeful work remains coherent.
- Toddler practical life
