Teacher-to-Child Ratio in Preschool: Why It Matters and What to Ask

Why it matters

Young children learn through back-and-forth conversation and need help with eating, toileting and big feelings. One adult with too many children ends up managing the room rather than engaging with anyone.

Sensible ranges

These are guides rather than rules, and schools differ. Lower is generally better, particularly for the youngest children.

• Under 1 year: about one adult for every three babies
• 1 to 2 years: about one adult for every four to six children
• 2 to 3 years: about one adult for every eight to ten, with a helper
• 3 to 6 years: about one teacher for every twelve to fifteen, with a helper

Ask the question precisely

• How many children are enrolled in this class right now?
• How many adults are in the room all day, and how many are trained teachers?
• Who covers when a teacher is absent?
• What is the ratio during daycare hours and at pick-up time?

Check it yourself

Count heads when you visit. The number on the website is sometimes the best case, not the daily reality.
