What Montessori Actually Costs in Arizona — and Why Almost Nobody Publishes a Price
We checked 15 Arizona Montessori schools for published tuition. Two listed a number. Here is what they charge, why the rest stay quiet, and how the figures compare to an ESA award.

Ask what Montessori costs in Arizona and you will get a shrug. We decided to find out the boring way: we opened 15 Arizona Montessori school websites and looked for a price.
Two had one.
What we found
- Children of Mary Montessori (Gilbert) — $799/month for five full days, $530 for three, $380 for two. Half-day: $599, $370, $260. Extended care $5/hour.
- Sounds Montessori (Phoenix) — tuition starting at $175/week, no registration fee.
- The other 13 — no figure anywhere on the site. Two discussed tuition without naming a number.
What those numbers mean annually
Children of Mary's $799 a month for a full-day, five-day place works out to roughly $8,000–$9,600 a year depending on whether you pay ten months or twelve. Sounds Montessori's $175 a week lands in a similar band — about $7,000 over a 40-week school year, more if you use it year-round.
So two independently-set prices, in two different cities, converge on roughly the same place: a full-time Montessori preschool place in metro Phoenix costs something in the region of $700 to $900 a month. Treat that as a rough anchor for your first phone call, not a quote.
The comparison that matters
That range sits remarkably close to an Arizona ESA award, which is funded at 90% of the state money that would have followed the child and has generally landed near $7,000 a year.
Which produces the central frustration of paying for Montessori in this state: the award roughly covers the cost, but not at the age you are paying it. ESA is universal only from kindergarten. The three- and four-year-old years — the ones you are writing cheques for — are covered only for children with disabilities. We went through that in detail in our piece on ESA eligibility.
Why the silence is not suspicious
It is tempting to read a missing price as a bad sign. Usually it is not. Small Montessori schools price on several axes at once — age group, days per week, half or full day, extended care — so a single headline number would misrepresent most families' actual bill. Children of Mary's published grid, with six combinations before add-ons, shows why one number is hard.
There is also a practical reason. Many schools would rather you saw the classroom before the invoice, and some adjust what families pay through scholarships. Neither is unreasonable. But the effect is that you cannot comparison-shop Arizona Montessori from your sofa. You have to call.
What to ask when you call
- The rate for the specific schedule you want — days per week, half or full day, for your child's age.
- How many months you pay. Ten-month and twelve-month billing look very different at the same monthly rate.
- What is on top — registration, materials, supply fees, extended care by the hour.
- Whether they take STO scholarships, and which organizations their families use most.
- What happens at kindergarten — the year fees often change and the year public options open up.
The free option people miss
Arizona has 26 tuition-free Montessori programs against 73 private ones — charters and district schools that charge nothing at all. They are concentrated in kindergarten and up and seats are limited, but for the elementary years the honest answer to “what does Montessori cost” can be nothing.

Frequently asked questions
How much does Montessori preschool cost in Arizona?
Of the 15 school websites we checked, only two published rates. Children of Mary Montessori in Gilbert lists $799 a month for a five-day full-day place and $599 for five half-days. Sounds Montessori in Phoenix advertises tuition starting at $175 a week. Those two points suggest a full-time place commonly lands somewhere around $700–$900 a month, but the sample is small and it will vary by city, hours, and age.
Why do so few Montessori schools publish tuition?
Small schools price by program, days per week, and age, so a single number would be misleading. Many also prefer to talk to families before discussing cost, and some adjust for scholarships. It is rarely evasive — but it does mean you cannot compare schools without contacting each one.
Is tuition-free Montessori available in Arizona?
Yes. Arizona has an unusual number of tuition-free Montessori options — public charter and district programs that charge nothing. They are generally kindergarten and up, so the preschool years are where families most often pay.
Does an ESA cover Montessori tuition?
Only from kindergarten, unless the child has a qualifying disability. The award is roughly comparable to a year of full-time preschool tuition, but the ages where Montessori costs the most are largely the ages ESA does not cover.
Rates were read from each school's own public website in September 2026 and may have changed. We have not verified them by phone. This is a small sample and is not a market survey. Spot an error? Tell us and we will fix it.
