How Public Montessori School Lotteries Work and Who Can Apply

A public Montessori program with more applicants than seats often fills them by random draw, after giving priority to groups such as brothers and sisters of enrolled children, staff members’ children or nearby families. Who can apply depends on the program. District magnets can limit applicants to an address or a zone, and charter schools set their rules within state law, so read the current year’s rules for each program on your list.

Who Can Apply to a Public Montessori Program?

These checks decide whether your family can apply at all.

• Where you live. One South Carolina district only took Montessori applicants who were zoned for one of the town’s schools or had a parent working full time for the district (district guidelines). A New Hampshire Montessori charter school takes state residents and asks for proof of residency (enrollment page).
• Your child’s age on the cutoff date. The same charter school requires kindergarten children to be 5 by September 1. What Age Can My Child Start Montessori? covers how cutoff dates work.
• Which grades have seats. For 2026-27, the South Carolina program accepted new applications only for its 3-year-old class, because its later grades were full.
• Cost. Public programs are tuition-free from kindergarten, but some charge for the years before it, as Are Montessori Schools Public or Private? explains.

Why Do Some Children Get Priority?

Child Trends looked at 288 public Montessori pre-K programs in a 2021 study. Of those, 53% used some form of lottery and 57% typically had a waitlist. Of the 37 program leaders the researchers surveyed, most gave certain groups priority, such as siblings of enrolled children and children of staff, even when they called their lottery random. The authors note that these preferences may favor families who have had access before (Child Trends, March 2021).

The order matters as much as the list. One Chicago Montessori magnet fills seats from its priority groups in this order, starting with siblings, then children of staff, then families who live close by, then the district’s tier groups, and finally everyone else (Chicago Public Schools). When a grade has few openings, the first groups can take them all.

What Does Federal Law Say About Charter School Lotteries?

The federal Charter Schools Program defines a charter school as one that admits students by lottery “if more students apply for admission than can be accommodated” (20 U.S.C. 7221i). A charter school in a network may first enroll students finishing the previous grade at an affiliated school, then fill the remaining seats by lottery.

The same law lets these schools run a weighted lottery that gives educationally disadvantaged students “slightly better chances for admission,” as long as state law doesn’t prohibit it (20 U.S.C. 7221b). None of this applies to district magnet programs, which follow district policy and state law.

How Did One District’s Montessori Lottery Run?

The South Carolina district above published its whole cycle for 2026-27. Applications were open from January 5 to January 23, 2026, closing at 4:30 p.m. on the last day, and families didn’t upload documents at that stage. The Montessori lottery ran online on March 27, and the deadline to confirm a seat was April 3. Its page listed no sibling preference for the Montessori program.

The page also told families already on its waiting list that the list hadn’t moved that year, and that they needed a new application to stay in the running.

What Happens on the Waitlist?

Waitlist rules vary from one program to the next. At the New Hampshire charter school, the 2026 application window ran from January 5 to March 6 and the lottery was held on March 11. Each family got one lottery number for the year, all numbers were drawn at random, and seats were filled grade by grade.

Children who weren’t drawn went onto a waitlist kept by grade and by lottery year, with each new year’s list placed below the older ones. Siblings on the waitlist came ahead of the general list. Families who got an offer had to return a letter of intent by its due date or lose the place.

So a waitlist can roll forward with you, as it does there, or end with the school year, as it did in South Carolina.

What Should I Do Before the Window Opens?

• Find the public programs near you in the Montessori Census and on your district’s magnet or school choice page.
• Write down each program’s application window, lottery date and confirmation deadline for the year you want.
• Check your child’s age against the cutoff date.
• Gather proof of address and your child’s birth certificate.
• List the priorities you qualify for, and ask how many seats are usually left after them.
• Ask whether a child in the program’s preschool keeps a seat for kindergarten.
• Keep a backup place, and set a date by which you’ll accept it if the waitlist hasn’t moved.

If you’re applying to a school that charges tuition as well, its deposit may come due before the lottery. Our guide on how to apply to a Montessori school lays the two calendars side by side. For every Montessori school in your area, public or not, pick your state in our US listings.
