There is no national license for daycare assistant teachers — the requirements are set by each state's child care licensing rules.
They cover a minimum age, a high school diploma or equivalent in some states, health-and-safety training around your start date, and a comprehensive background check under federal CCDF rules.
Head Start adds its own federal minimum for assistants, and BLS notes some states and employers ask for a credential, most often the CDA.
Do assistant teachers need qualifications?
No national license exists for the assistant teacher role.
States license child care centers and write staff qualifications into those licensing rules, so what an assistant teacher needs is decided by the state child care licensing agency, not by a federal credential.
What varies from state to state is the paperwork: the minimum age, the education floor and any pre-service training.
National counts of state requirements come from secondary scans such as the Bipartisan Policy Center's 2024 work, not from licensing sources, and BPC's own publications give different counts on adjacent questions.
Treat any national snapshot as a starting point and confirm your state's rule directly with the agency.
Titles do not map one-to-one onto licensing tiers: state rules can treat assistant teacher, teaching assistant and aide as separate tiers with different minimums, and Rhode Island's are a case in point.
Our teacher aide guide covers the aide tier, and the assistant teacher career guide covers what the role does day to day.
One federal requirement reaches this role in every setting CCDF covers: under 45 CFR 98.43, every child care staff member of a licensed, regulated or registered provider — and any subsidy-eligible provider — must have a comprehensive background check.
A state can set no education rule for assistants and the federal background check still applies.

Assistant teacher age and education requirements
Minimum ages come from state licensing rules, and the spread is wide.
South Dakota center assistants may be 14 but may not be left alone with children, and Oregon's Aide I tier starts at 14 with the same limit for anyone under 18; Wisconsin's assistant child care teacher must be at least 16, and Minnesota's assistant teachers at least 18.
A Bipartisan Policy Center list from February 2024 gives different ages for some of these states, so the state child care licensing agency is the authority on your state's current minimum.
Other state center rules show the same spread:
- New York. An assistant teacher needs a high school diploma or equivalent, or one year of experience working with children under 13 (18 NYCRR 418-1.13(g)(5)).
- Arizona. An assistant teacher-caregiver must be at least 16 and be enrolled in high school or HSE classes, hold a diploma or equivalent, be in vocational rehabilitation, or have 12 months of experience as an aide or volunteer (A.A.C. R9-5-401(4)).
- Rhode Island. A Teacher Assistant must be at least 18 with a high school diploma or GED; Teacher Aides may be 16, but must always be with staff aged 18 or older.
- Georgia. In centers licensed for 19 or more children, caregivers and aides assisting the lead teacher must be at least 16, and no 16- or 17-year-old caregiver or aide may be solely responsible for children; in centers licensed for 18 or fewer children, caregivers and aides must be at least 18 (Rule 591-1-1-.31(3), (4)).
On education, BLS describes a high school diploma or equivalent as the typical entry-level education for childcare workers, and notes that some states have no education requirement for entry-level positions.
The associate-degree figure you see attached to "preschool teacher" belongs to the lead tier: BLS puts preschool teachers at typically at least an associate's degree, with requirements varying by setting and state.
Training before you start
BLS summarizes what licensure often involves for childcare staff: passing a background check, having a complete immunization record and meeting a minimum training requirement, with some states requiring CPR and first aid certification.
The background check is a federal floor rather than a state add-on.
Under CCDF rules it must be requested before you become a staff member, and it includes an FBI fingerprint check, a National Sex Offender Registry search, and registry and criminal history checks covering your current state and every state you lived in during the past five years; it must be repeated at least once every 5 years.
Start timing has a federal answer too: a new hire may start work once there is a qualifying result on either the FBI fingerprint check or the in-state fingerprint criminal check, and must be supervised at all times by a fully checked staff member until every component is complete.
Training rules name the clock time, and states differ.
Georgia requires center direct-care staff to complete DECAL-approved health and safety orientation training — 11 CCDF topics including safe sleep, medication administration, abusive head trauma, emergency preparedness and child abuse reporting — within the first 90 days of employment (Rule 591-1-1-.33(3)).
Wisconsin centers must complete a new employee's orientation within the first week, covering the rule, center policies, emergency plans, food allergies, first aid, medication administration and infection control (DCF 251.05(4)(a)).
Assistant teacher credentials in some states
BLS notes that some states and employers require childcare workers to hold a nationally recognized credential, most often the CDA awarded by the Council for Professional Recognition, which must be renewed every 3 years.
Where a state writes an assistant tier into its licensing rule, the credential question is answered in the same chapter:
- Wisconsin. An assistant child care teacher must be at least 16, work under a child care teacher, and — within 6 months — complete either 2 early childhood education credits or one department-approved non-credit course, Introduction to the Child Care Profession (DCF 251.05(3)(g)).
- Minnesota. Assistant teachers are their own tier under Rule 3: at least 18 and working under a teacher. A high school graduate needs 2,080 hours of experience as an aide or student intern plus 12 quarter credits; a CDA holder needs nothing more (Minn. R. 9503.0033).
The Minnesota rule shows what a credential is worth at this tier: the CDA replaces hours and credits an uncredentialed assistant would need to accumulate.
Vermont runs the check in the other direction — a CDA plus 12 months of experience qualifies someone at the teacher assistant level there, but not as a lead teacher.
These are center licensing rules, scoped to each state and to the center setting.
If your state names its entry tier something else — assistant caregiver, teaching assistant, trainee — the licensing agency's rule chapter decides what applies to you.
Pre-K and Head Start assistant teacher requirements
Head Start sets a federal minimum that names assistant teachers directly.
Under the Office of Head Start's standards (45 CFR 1302.91), a Head Start preschool assistant teacher must, at minimum, hold a CDA — or a state certificate that meets or exceeds it — or be enrolled in an associate or bachelor's program, or be enrolled in a CDA program to be completed within two years of hire.
That standard binds Head Start programs; a private center is licensed under its state's rules instead.
The requirement is statutory, which matters while the rules are in motion: ACF's August 2026 proposal to rescind and replace the Head Start Program Performance Standards would keep the statutory staff qualifications — a list that includes preschool teachers and assistant teachers — and drop several regulatory ones.
Neither that proposal nor the May 2026 proposal on Head Start wages and benefits was final as of October 5, 2026.
State-funded pre-K programs can set their own staffing standards.
NIEER's 2025 State of Preschool yearbook counted 21 of 63 state-funded pre-K initiatives meeting its quality benchmark requiring assistant teachers to hold a CDA or equivalent — a benchmark NIEER tracks, not a rule each program imposes.
Programs can also set scheduling conditions: NC Pre-K requires lead and assistant teachers to be in direct contact with children at least 32.5 hours per week, with the rest of a 40-hour week for planning.
Moving up from assistant teacher to lead teacher
The assistant tier sits at the bottom of the same ladder the lead-teacher rules climb.
Wisconsin writes the step into its teacher rule: a child care teacher there must be at least 18, have completed high school or equivalent, have 240 hours of experience as an assistant teacher (or in another approved setting), and complete 4 ECE credits or two department-approved non-credit courses before starting, among other options (DCF 251.05(3)(f)).
Minnesota counts the same experience differently: under Rule 3, a teacher with a CDA credential (preschool or infant/toddler) needs 1,560 hours as an assistant teacher, aide or student intern and no additional education.
BLS puts the destination tier at typically at least an associate's degree for preschool teachers, with requirements varying by setting and state.
What you need to move up is spelled out in your state's lead teacher requirements — the credential, clock hours and coursework each rule accepts, state by state.
If you are choosing a first credential as an assistant, note which ones the rules above name: the CDA is the credential BLS calls most common, the one Minnesota's rule credits directly, and one of the routes Head Start accepts for its assistant teachers, alongside a state equivalent or enrollment in a degree or CDA program.
