“Toddler Rooms/16 months to 36 months 5 to 1 if 15 children are present; 7 to 1 if less 15”
“Preschool Rooms/30 months to 72 months 10 to 1 20” Washington allows up to 10 children per adult at this age.
The state’s rule
Washington sets the most children one adult may care for by age, and the largest group size, in WAC 110-300-0356(5).
Infants (birth through 11 months): one adult for every four.
Toddlers (12 through 29 months): one adult for every seven.
Preschoolers (30 months through 6 years, not in kindergarten): one adult for every ten.
School-age children: one adult for every fifteen.
What to know
The license is the range the state allows. It does not say which ages have openings.
