Free Preschool in St. Louis Has Two Rules: An August 1 Birthday and Potty Training
Revised October 30, 2026
Is preschool free in St. Louis?
It can be. Saint Louis Public Schools offers free preschool for children who are fully toilet trained and have turned 3 or 4 before August 1 of the school year, with a 10:1 student to teacher ratio and free breakfast and lunch. Outside the city, ask your own district. Private preschool in Missouri averages $750 to $900 a month, per Child Care Aware of Missouri.

The district’s own admissions page says it offers free preschool for students who are fully toilet trained and have turned 3 or 4 prior to August 1st of the upcoming school year. Two lines. One is a birthday. The other is a bathroom.
If you are reading this with a sticker chart on the fridge and a pile of tiny underwear on the dryer, you already know which line is harder. The timer on your phone goes off every forty minutes. The little step stool scrapes across the tile. Somebody announces, proudly and too late, that they had to go. You are not doing anything wrong. You are just on the clock, and almost nobody told you there was a clock.
That is the leverage point for a St. Louis parent picking a preschool: before you tour a single lobby, know which free door your child can walk through, which record to pull, and what a real month of tuition costs. The tour comes last.
Is preschool free in St. Louis?
It can be. Saint Louis Public Schools offers free preschool for children who are fully toilet trained and have turned 3 or 4 before August 1 of the school year they start. The district lists a 10:1 student to teacher ratio in every classroom, free breakfast and lunch served at school, before and/or after care at all schools, and district transportation for eligible 4-year-olds. Registration runs through Focus, the district’s student information system.
Outside the city line, call your own school district and ask the same question. If the answer is no, you are shopping private, and the price changes the whole conversation.
The birthday line and the bathroom line
Do the birthday math first, because it is the line you cannot move. A child who turns 3 before August 1 fits the district’s cutoff for that fall. A child who turns 3 in mid-August waits a year for the free seat. Same height, same vocabulary, same love of the big slide. Different calendar. Put the August 1 date on the fridge next to the sticker chart and count backward.
Then the bathroom line. “Fully toilet trained” is the district’s phrase, and it is worth asking the school office what it means in practice before you enroll, so the first week does not end with a phone call and a bag of wet clothes at pickup. Ask it plainly: what happens if my child has an accident in the first month?
There is a quieter benefit on that same SLPS page that matters to working parents: the district lists the ability for preschool students to attend the same school as older siblings. One drop-off line instead of two. One car door, one wave, one coffee going cold in the cupholder instead of two.
Here is the line worth texting the friend who is about to put down a deposit: in St. Louis, the difference between free preschool and a private tuition bill can come down to a birthday before August 1 and a kid who can make it to the bathroom alone.
Pull the record before you fall for the lobby
A tour is built to make you feel something. The bright cubbies, the smell of crayons and floor cleaner, the tiny chairs, the teacher who kneels to say hello to your kid by name. All of it is real, and none of it tells you what an inspector found on the last visit. So look first.
In Missouri, the state’s Child Care Search lets you search for a facility by name. Read its own warning, too: the records available for review on that site may not reflect the complete history of a child care facility’s compliance. Public records on a licensed or license-exempt program can be requested from the Missouri Department of Elementary and Secondary Education, Office of Childhood. A thin record online is a reason to ask for the full file, not proof that nothing is in it.
In the Metro East, the Illinois Sunshine website is the state’s resource for anyone interested in licensed child care in Illinois, with a monitoring report search and a page on how to make a licensing complaint. Families in Belleville get the same advice as families in Affton: read what the inspector wrote, then ask the director about it by name.
Rather talk to a person? Illinois DCFS lists a Day Care Information line at 1-877-746-0829. Have the program’s exact name and address in front of you when you call, and a pen, because the person on the other end will move faster than you can type.
That question changes the tour. You stop being a guest and start being the parent who did the homework. A good director answers without flinching and tells you what changed. A defensive one has just told you something too.
Church preschools and home daycares play by different rules
Plenty of St. Louis families end up in a church basement classroom, and plenty of them love it. Know what it is. The state education department describes a child care center operated by a religious organization as “a regulated, license-exempt facility.” Programs under the exclusive control of a religious organization are license-exempt under Section 210.211, RSMo, and must still comply with certain child care laws and regulations.
Among the documents the department lists for these religious organization child care centers is a Notice of Parental Responsibility. Ask for yours at enrollment and read it at the kitchen table, not in the hallway with a toddler pulling on your sleeve.
Home daycare sits on a threshold. The same Missouri statute says its licensing rules do not apply to a person caring for six or fewer children, including a maximum of three children under the age of two, at the same physical address. So the warm living room with the gate across the stairs may be perfectly good, and may never have seen an inspector. Ask how many children are there on a full day, and how many are babies.
What a month of preschool really costs in Missouri
If the free seat is not an option, here is the number to brace for. Child Care Aware of Missouri puts average monthly costs at $750 to $900 for preschool care, $850 to $1,000 for toddler care and $1,000 to $1,200 for infant care. Feel that in the checkbook: preschool alone can run past a car payment, every month, for years.
Three things move the bill. Hours: five half-days is a different product from a full day. Calendar: a school-year program and a year-round center are not the same price, even when the monthly rate looks close. Fees: registration, supplies and a deposit sit on top of the quoted rate. Ask for the rate sheet, in writing, before you fall in love with the reading corner.

Help paying, and the waitlist nobody mentions
Missouri’s Office of Childhood monitors participation in the state’s Child Care Subsidy Program, the program families lean on when tuition outruns the paycheck. Know this before you count on it: Missouri now places new Child Care Subsidy applications on a waitlist. Families are placed based on the date their application was submitted and by a priority ranking, with children with special needs first.
The practical move is the same every time: apply early, because the date counts, then keep looking at programs while you wait. Questions go to the families line at 573-415-8605. And ask every program on your list whether it accepts subsidy before you tour it. Some don’t, and you want to know that before your kid falls for the sandbox.
Somewhere between the sticker chart and the first day of school, the first dentist visit sneaks up too.
What to watch on the tour
Go mid-morning, when the room is doing what it really does. Stand still for ten minutes. Listen. A good room has a hum, not a roar: a teacher crouched at eye level, a kid narrating a block tower, someone singing the clean-up song slightly off-key. Then watch the adults, not the toys. Notice who looks up when your child walks in, and who keeps their eyes on the kids already in the room. Both answers tell you something.
- Count the room. Children and adults in the room your child would join. Compare it with what the director told you on the phone.
- Ask how long the lead teacher has been here. It is the one question most parents skip, and the answer tells you more than the curriculum binder.
- Watch a hard moment. A three-year-old will melt down while you are standing there. How an adult handles that is the whole tour.
- Look at the bathroom. Unglamorous, and the fastest read on how a place actually runs. It matters double if your child just learned to use one.
- Name what you found in the record. Ask what changed. Listen to the tone of the answer as much as the words.
- Ask the sick-day rule out loud. The fever threshold, how long a child stays home, and how fast they expect you at the door.

The monthly check
What is the average cost of daycare in St. Louis?
Plan on a payment the size of a car note, every month. Child Care Aware of Missouri averages $1,000 to $1,200 a month for infant care, $850 to $1,000 for toddlers and $750 to $900 for preschool, with registration, supplies and a deposit due on top.
Frequently asked questions
Which type of preschool is best?
The one your child can get into, that you can afford, with a clean record and a lead teacher who has stayed. In the city, check the free St. Louis Public Schools seat first. Then compare private, church and in-home programs on the same three things: the state record, how many children each adult watches, and how long the teachers have been there.
What are the signs of a good preschool?
A room that hums instead of roars, adults at a child’s eye level, a lead teacher who has been there a while, and a director who can talk about the inspection record without getting defensive. A clean, well-stocked bathroom says more than the art on the walls.
What is the best age for a kid to start preschool?
Readiness matters more than the number. In St. Louis Public Schools, the free program takes children who have turned 3 or 4 before August 1 and are fully toilet trained, so for many city families those two lines set the start date.
Which is better, Montessori or regular preschool?
Neither wins on the label. If the method matters to you, ask where the lead teacher trained in it and how long they have taught that way. Then judge a Montessori room by the same things as any other: the state record, the adult-to-child count and the way a hard moment gets handled.
How much does preschool cost in Missouri?
Child Care Aware of Missouri puts average monthly costs at $750 to $900 for preschool care, $850 to $1,000 for toddlers and $1,000 to $1,200 for infants. Registration, supply fees and deposits sit on top of the monthly rate.
What are red flags in a daycare?
A director who won’t discuss the inspection record, a room with more children than adults can watch, a tour that steers you away from the bathroom, and a church or home program that cannot hand you its paperwork. Vague answers about the sick-day rule are a warning too.
How to look up daycare licensing violations?
In Missouri, use the state Child Care Search site, and remember its own note that the records shown may not reflect a facility’s complete history. In Illinois, use the Illinois Sunshine website’s monitoring report search.
Are daycare licenses public record?
In Missouri, public records on a licensed or license-exempt child care facility can be reviewed or requested from the Department of Elementary and Secondary Education, Office of Childhood.
