Admissions requirements, class sizes, tuition and financial aid for 153 accredited independent Montessori schools, checked on each school’s own website.
Montessori schools use mixed-age classrooms, hands-on materials and child-led work periods, and most do not use an entrance test. This list covers the 153 accredited independent schools in our national database whose own websites describe a Montessori program, from toddler and primary programs to Montessori middle and high schools.

Testing summarizes the rule for the main entry grades. Many schools test only some grades, so select a school for its full profile, including the complete testing policy, mission, signature programs, ratio, tuition, financial aid and the official pages we used. Deadlines are for fall 2027 entry unless another cycle is noted. Blank means the school does not publish that information.
Most do not. Of the 153 Montessori schools in this list, 138 use no published entrance test or rely on their own observation visit. A few that continue through high school require the SSAT or ISEE for upper grades.
Among the 10 Montessori schools that publish an average class size, the median is 15.5 students.
115 of the 153 Montessori schools in this list describe need-based financial aid on their own websites. Use the Financial aid filter to see them, along with merit scholarships and income-based tuition options.
In our database, the states with the most Montessori schools are MA (19), NC (12) and IL (10).
Every school here is an accredited independent school whose own website describes it this way. We read each school’s admissions, tuition, about and affordability pages in September and October 2026 and did not use ranking or directory sites.
ConnectPrep helps families build balanced school lists, prepare applications and interviews, and get ready for the SSAT, ISEE and HSPT, online nationwide and in person in Connecticut, New York and New Jersey.
This list is drawn from ConnectPrep’s national database of accredited independent schools, built from the member directories of NAIS, TABS and the regional independent school associations. Each school’s testing policy, deadline, grades and tuition were read on its own admissions and tuition pages in September 2026, and a second pass in October 2026 recorded mission, approach, signature programs, class size, ratio, enrollment, founding year and financial aid from the school’s own about, academics and affordability pages. A school appears here only when its own website describes it this way. Directory and ranking sites were not used. Blank fields mean the school does not publish that information. See every school by region on our national private school requirements hub.
