Half-day or full-day preschool: which is right for your child?

The most important stretch of a Montessori day happens before lunch. From 8:30 to 11:30, every child at Beacon, half-day and full-day alike, is in the same three-hour work period: choosing work from the shelves and getting lessons from the teacher. Nothing academic is saved for the afternoon.

So you are not choosing between less school and more school. You are choosing what happens after lunch: whether your child goes home during the 11:30 to 12:15 pickup window, or stays for recess and the afternoon. For the full hour-by-hour rhythm, see our walkthrough of a typical preschool day.

Here is our actual schedule, not an idealized one:

• 8:00 to 8:30: arrival
• 8:30 to 11:30: three-hour morning work period (every child)
• 11:30 to 12:15: lunch, and half-day dismissal
• 12:15 to 1:15: outdoor recess
• 1:15 to 2:45: afternoon work period or nap, full-day dismissal at 2:45
• 3:00 to 5:00: optional afterschool enrichment

Afterschool is optional enrichment: Karate, Soccer, Spanish, Chess, Theater, and Dance. A full-day child can go home at 2:45 or stay for an activity until 5:00. The schedule is the same across our Toddler and Primary classrooms, so siblings on different schedules still share one drop-off.

Half day tends to fit three situations. A young child who is new to group care and runs out of steam by late morning. A child who still needs a long early-afternoon nap and sleeps well only at home, in a familiar bed. And a family with a parent or caregiver who can reliably be at the door between 11:30 and 12:15, because that pickup window is firm.

The tradeoff is real: a half-day child misses recess with classmates and the whole afternoon block, and a midday pickup is close to impossible for two full-time working parents. If that describes your household, do not talk yourself into a schedule your logistics cannot support. Half day is a schedule choice, not a virtue.

Full day fits working parents first. Dismissal at 2:45, plus afterschool until 5:00, covers a normal workday without a patchwork of sitters. It also fits most children from about 4 up: by then the nap is usually gone, and the 1:15 to 2:45 block becomes a second work period. Kindergartners in particular use that quieter afternoon for longer, harder work than the busy morning allows.

Commute math matters more than parents expect at 5:00 on a Tuesday. Our building at 320 Boston Post Rd in Weston is on Route 20, which runs straight into Wayland, so pickup is a short, predictable drive for Wayland families heading home.

From 1:15 to 2:45, younger full-day children rest on cots while older children work. Expect some turbulence at the start: a child who naps two hours at home may sleep forty-five minutes at school, or refuse entirely, for the first few weeks. Teachers offer rest without forcing sleep, and most children settle into a school nap within a month.

A few never do. For those children, a temporary half-day schedule or an earlier pickup beats a nightly meltdown at 5:30. Tell the teachers exactly what sleep looks like at home, and watch the daily Brightwheel updates, which tell you whether and how long your child slept, so you can adjust bedtime instead of guessing.

Full day costs more than half day everywhere, and afterschool adds on top. For typical Massachusetts numbers and what drives them, see our guide to preschool costs in Massachusetts. We share our own rates privately; request them through the tuition page and you will get current figures for each schedule.

Switching later is common and small. Half-day and full-day children share the same classroom and the same teachers, so extending to full day mid-year, when stamina grows or a work schedule changes, is not a new adjustment for your child. Families often start half day in September and go full day after winter break. Moving the other way works too. If you are stuck, start with the schedule your logistics require, then let the first few months decide the rest. Or come watch a morning first; our what to expect page shows the format.
