Montessori Preschool in South San Francisco
Preschool II is where the method does its most visible work: children choose their own tasks, stay with them as long as they hold, and start reading and calculating because they wanted to. Mills is in South San Francisco, at 1400 Hillside Blvd. in South San Francisco.
Why families here choose it
For a South San Francisco family the deciding factor is rarely the classroom photos. It is knowing the fee before the tour, and knowing there is a fifth grade at the end of it.
This is our own city. The school sits on the hill above downtown, which is why families have called it “the school on the hill” for decades. For most South San Francisco families the drive is a few minutes, and the 7:30 am opening exists because so many parents are heading down to the biotech campuses before eight.
What Montessori preschool at Mills actually is
These are the years Montessori was designed around. A three- or four-year-old in a prepared classroom is in the middle of what Montessori called the absorbent mind — language, order and fine motor control are all arriving at once, and the room is arranged so a child can chase whichever of them has their attention today. Reading usually appears not as a lesson but as a sudden realization, somewhere in the fourth year, that the sandpaper letters they have been tracing make words.
- The uninterrupted work cycleA long morning block with no bell cutting it in half. A four-year-old who is deep in something is left in it — protecting concentration is the single most Montessori thing a school does.
- Concrete before abstractChildren hold the golden beads before they meet the number. Mathematics starts in the hands, which is why the abstract version comes easily later.
- Mixed ages, on purposeA three-year-old watching a four-year-old is getting a lesson no adult can give as well. The four-year-old explaining it is learning it twice.

What South San Francisco families ask about Montessori preschool
- Is this the same as pre-K at an ordinary preschool?The hours look similar; the day does not. No whole-class instruction to keep up with, no craft everybody makes the same way, and no timetable chopping the morning into twenty-minute pieces.
- Will my child be ready for kindergarten?We do not publish attainment claims about our own children — we have not measured it. What the year is actually for is the readiness that transfers: choosing work, staying with it and finishing it without being chased.
- Is the Montessori preschool different for families traveling from South San Francisco?No — there is one program and one campus. What changes with distance is the schedule that suits you: families driving further usually choose the extended full day so they are not fighting the peak twice a day.
- What does it cost?Between $1,100 and $1,750 a month depending on the program, days per week and length of day, plus a one-time $200 enrollment fee. Every figure is on the tuition page — we do not make you ask.
- Can we start mid-year?Yes. Enrollment is open all year, subject to availability, so families move to us when a childcare arrangement changes rather than waiting for September.
- What happens after kindergarten if we come from South San Francisco?The same school. Mills runs through fifth grade, so the kindergarten year is not the exit — which is the main reason families take on a drive at all rather than enrolling somewhere closer that finishes at five.
- We are in the South San Francisco Unified School District. Does that affect enrollment?No. Mills is a private school and enrollment has nothing to do with district boundaries. The district matters only in that it is your free alternative, and it is a fair thing to weigh — we have written an honest comparison with California TK that argues both sides.
