How to start a Montessori school or Montessori daycare

Montessori is not a licensing category of its own in the state rules our research read.

States license child care by structure — center, family child care home or, in some states such as Kansas, preschool — and your program lands in whatever category your state's rules create for its hours, ages, meals and setting.

The method shapes your classrooms; the category comes from the structure.

Kansas is the clearest named example of the category question: its rules license preschools as a category separate from child care centers, defined by sessions of no more than three hours, no more than one session per child per day, children 30 months and older who are not yet kindergarten-eligible, and no meals served — and the rule states the term includes educational preschools and Montessori schools (K.A.R. 28-4-420).

A Montessori program that fits that definition is licensed as a preschool in Kansas, not as a center.

That half-day, no-meals structure is really the preschool question, and our guide to how to start a preschool owns it in depth.

School status and accreditation can also change which rules reach you.

In Texas, a kindergarten or preschool program run as part of a public school or a TEA-accredited private school offering grades through six is exempt from child care licensing when it provides no before- or after-school custodial care (Texas Human Resources Code 42.041(b)(9)).

The exemption turns on the school's structure and accreditation, not on the method: a Montessori program fits it only where it is operated as part of a public school or a TEA-accredited private school and provides no before- or after-school custodial care.

It is one state's rule, printed here as an example of how the category question works, not a pattern to assume.

A Montessori program run from a home — a Montessori home daycare — falls under your state's family child care home rules wherever a home program must be licensed, a separate rulebook from the center rules.

Capacity, staffing and training minimums for homes are set in the home category, so plan a home program from the home rules rather than from center numbers.

The licensing steps themselves — application, background checks, inspection — are the ones any licensed program works through, and our guide to how to start a daycare walks them in order.

How long licensure takes and what the fees are is set state by state: the agency pages our research read do not support a national timeline or fee figure, so ask your state child care licensing agency for both before you set an opening date.

Confirm the category before you commit: licensing categories, exemptions and fees are set state by state, and they change.

Ask your state child care licensing agency which category a Montessori program with your hours, ages and setting falls into — before you sign a lease or enroll a child.

The facility side runs through three gatekeepers: local zoning, building and fire code, and your state child care licensing agency's review of the rooms children will use.

Application requirements force those decisions early — a Maryland child care center application, for example, must include zoning and building code compliance, floor plans, a written plan of operation, workers' compensation insurance information, a fire evacuation plan, a personnel list and a staffing pattern (COMAR 13A.16.02.02).

That is one state's list, and a useful preview of the documents to expect from your own agency.

Licensed capacity comes from your state's staff-to-child ratios and maximum group sizes for each age band, applied to the rooms you actually license.

The same floor plan supports different capacities under different age mixes, which makes the age bands you choose a facility decision as much as an enrollment one.

Materials deserve their own line in the facility plan.

AMI/USA describes its teacher training as including material preparation, and a classroom built around materials needs somewhere to put them — plan the shelving, storage and work space in your floor plan rather than retrofitting after licensure.

Build-out cost is the number to get locally: our research did not verify a per-square-foot build-out figure for child care spaces from any primary source, so price the work with contractor bids against your actual floor plan and your state's requirements instead of trusting a national number.

Confirm before you sign a lease: zoning, building code and facility requirements are set by your city or county and your state child care licensing agency.

Walk both checks in writing before you commit to a building.

Two qualification layers stack on a Montessori hire.

Your state's child care licensing rules set the baseline for everyone who works with children — minimum ages, pre-service and annual training hours and role definitions for teachers and directors are your state's to set — and those rules apply in your program the way they do in any licensed one.

Background checks have a federal floor as well: under federal CCDF rules, every child care staff member of a licensed, regulated or registered provider must have a comprehensive background check (45 CFR 98.43).

Where a state makes room for a Montessori program, it does so in writing in its own rules.

The Montessori layer sits on top: the training your guides hold.

AMI/USA describes its training as covering educational theory and child developmental psychology, classroom observation, practice teaching and material preparation — so verify training directly rather than by job title.

Ask each candidate for the training organization, the training center, the diploma level and the dates, and check anything unclear with the organization that issued it.

In the interview, the training content gives you the probe: a trained guide should be able to talk through the classroom observation and practice teaching their training included and the materials they prepared, not just name a credential.

Write that standard into the posting before you recruit, so every applicant answers to the same bar.

Ratios still run your rooms: your state's staff-to-child ratios and group sizes apply to your classrooms for each age band, and the flexibility our research found is a state's written rule, not a credential.

Maryland lets a Department-approved Montessori school exceed a staff/child ratio or group size requirement by no more than one-third (COMAR 13A.16.08.03).

Treat that as what it is — one state's written allowance — and confirm with your licensing agency whether your state has one before you build a staffing plan around it.

For the hiring mechanics around those ratios — role mix, sequencing hires before opening, and coverage from day one — our guide to staffing a new program walks the process end to end.

Confirm before anyone is scheduled: staff qualifications, background checks and training hours are set by your state child care licensing agency, and ratio allowances for Montessori programs exist only where a state writes them into rule.

Confirm the current rules with the agency before you hire or schedule staff.

Two sourced numbers anchor the budget.

A September 2021 U.S. Treasury report, citing a Center for American Progress cost analysis, put wages at no less than 50-60 percent of child care expenses on U.S. averages, with labor's share larger for infant care — staff is the dominant line before you add anything Montessori to the model.

The same report warns what the margins look like: most for-profit child care facilities, it said, operate on razor-thin profit margins usually below 1 percent.

Budget from the payroll up, and treat any projection that assumes full enrollment from day one as fiction — rooms fill as families enroll, not before.

A Montessori budget keeps that structure and adds its own lines: trained-guide payroll, Montessori materials for each classroom, and training costs for staff you develop after opening.

None of those lines have verified national figures in our research, so price training with the training organization itself and materials with the suppliers you will actually buy from.

The unverifiables stay unverifiable here: there is no verified national figure for licensing application fees or timelines, and no verified per-square-foot build-out figure for child care spaces.

Pull the fee schedule from your state child care licensing agency and the build-out price from contractors bidding your floor plan.

Because labor dominates the budget, your staffing plan is your budget: every room's ratio-driven headcount is the cost engine, which is why the staffing decision belongs before the lease in your launch plan.

Opening a Montessori school is a sequence, and the order saves money: the licensing category decides the facility, the facility and ratios decide the staffing plan, and the staffing plan decides most of the budget.

Work the steps in that order.

1. Confirm the category. Bring your planned hours, ages, meals and setting to your state child care licensing agency and ask which category a Montessori program with that shape falls into — center, preschool or family child care home.
2. Get the application packet and the fee schedule in writing, before you spend on anything else.
3. Design the floor plan against capacity: your state's ratios and group sizes for the age bands you choose, plus the shelving and storage a materials-based classroom needs.
4. Write the staffing plan next: headcount per room from the ratios, the qualification level your state sets for each title, and the Montessori training standard you will verify for guides.
5. Recruit guides before you open, with background checks and orientation built into every start date.
6. Choose your quality standard on top of licensing: NAEYC's accreditation system lists Montessori among the program types eligible to seek accreditation, and training recognition is a separate, additional choice — a quality decision, not a substitute for the license.

How long the license takes is your state's number, not a national one: Idaho's law, for example, requires the state to issue a basic daycare license within 60 days once requirements are met, and the license is then valid for two years (Idaho Code 39-1106) — a clock that starts at met requirements, not at the day you decided to open.

Ask your agency for your state's sequence and work backward from it when you set an opening date.
