Every state sets its own minimum qualifications for teachers in licensed child care centers. Assistant teachers usually need to meet a minimum age and pass required screenings. Lead teachers usually need more: early childhood education (ECE) coursework, a Child Development Associate (CDA) credential, or a degree, plus experience with young children.

Frequently asked questions
Do you need a degree to be a preschool teacher?
Not in most licensed child care centers. Many states accept a CDA, a set number of ECE college credits, or experience. Washington, DC is an exception: lead teachers need an associate degree or equivalent credits. Public school pre-K programs usually require a bachelor’s degree and a state teaching license.
What is the minimum age for child care teachers?
Lead teachers usually must be at least 18. Some states set it higher, including Massachusetts (21), Connecticut and Vermont (20), and Maryland, Michigan, and Illinois (19). Assistants and aides can often start at 16, and a few states allow 14 under close supervision.
Does a CDA count toward teacher requirements?
In most states, yes. A CDA is one of the most widely accepted ways to qualify as a lead teacher.
How much ongoing training do child care teachers need?
It ranges from about 4 hours a year in Idaho to 24 or more in several states, including Alaska, Minnesota, Nevada, and Rhode Island, and Maine requires up to 30 depending on hours worked. Most states fall between 10 and 20 hours.
