What age can a child start preschool? Age boundaries and staff-to-child ratios for daycare centers and toddler classes

Age boundaries: Under 2 go to daycare centers; at 2 they can enter preschool

This line is drawn by law, not set by individual schools. Article 3 of the Early Childhood Education and Care Act defines a 'young child' as 'a person from age two through the period before entering elementary school,' so preschool enrollment begins at age 2. Children under 2 are cared for by daycare centers under Article 2 of the Establishment Standards for Child and Youth Welfare Institutions, which expressly defines a daycare center as 'an institution providing childcare services for children under age 2.' The two even fall under different authorities: preschools fall under the Ministry of Education (via county/city education bureaus), while daycare centers fall under the Ministry of Health and Welfare (via county/city social affairs bureaus). This is also why the search channels differ — for preschools, check the Ministry of Education's 'National Preschool Education Information Network'; for daycare centers, check each county/city social affairs bureau's childcare resource website.

The transition gap after turning 2: You may extend daycare, but for at most one year

Many families get stuck here: a child's birthday falls in the middle of the school year, the child has turned 2 but preschool admissions have already ended, so they have to wait until the next school year. Article 5 of the Establishment Standards for Child and Youth Welfare Institutions explicitly addresses this — a child who has turned 2 but has not yet entered preschool may continue to be cared for in a daycare center, 'for a period not exceeding one year.' In other words, this transition gap is legally permitted but has a cap: one year at most, and the child cannot remain in the daycare center indefinitely. In practice, it is recommended to learn about the admissions timeline of target preschools in the year the child turns 2 (public and nonprofit preschools mostly hold registration and lotteries in the first half of the year) to avoid compressing the transition period.

What is a toddler class? Why are places so hard to get?

A 'toddler class' refers to a class in a preschool that enrolls children aged 2 and above but under 3. It is not a separate type of institution but an age-based class within a preschool. The reason places are scarce is written directly in the law: under Article 16 of the Early Childhood Education and Care Act, a toddler class with no more than 8 children must have 1 preschool educator, and one with 9 or more must have 2; for classes for children 3 and above, the requirement is 1 for up to 15 children and 2 for 16 or more. With the same single educator able to look after only 8 children in a toddler class but 15 in an older class, the labor cost is almost double. As a result, most schools run far fewer toddler classes than middle and upper classes. This is a structural supply constraint, not an admissions strategy of individual schools.

Statutory staff-to-child ratios for the three stages at a glance

Care density decreases with age, and all ratios are statutory minimums rather than suggestions: (1) Daycare centers (under 2) — under Article 11 of the Establishment Standards for Child and Youth Welfare Institutions, there must be 1 dedicated childcare worker for every 5 children, with fewer than 5 counted as 5; (2) Toddler classes (2 and above, under 3) — 1 preschool educator per class of up to 8 children, 2 for 9 or more; (3) Ages 3 and above up to before elementary school — 1 per class of up to 15, 2 for 16 or more. It is worth noting that these are minimum standards for 'must have,' and individual schools may provide more staff. When visiting, you can directly ask about the actual number of children and educators in the class and compare it with the statutory minimums above.

How to decide which type you need and where to look

First, look at the child's actual age: under 2, you can only use a daycare center (or an in-home childcare provider, commonly called a nanny/babysitter); from age 2, you can look for a toddler class at a preschool, or remain at a daycare center for at most one more year. Next, consider timing: registration and lotteries for public and nonprofit preschools are mostly concentrated in the first half of each year; if you miss them, you have to wait until the next school year, so it is recommended to start checking in the winter before the child turns 2. As for where to look: for preschool licensing and types, visit the Ministry of Education's 'National Preschool Education Information Network' (ece.moe.edu.tw); for daycare centers, check the childcare services section of your county/city social affairs bureau. This site has compiled lists of licensed preschools by county/city and district, which can help you filter by geographic area, but for licensing status and the latest admissions information, please rely on the official systems.
