A pre-K assistant teacher is the second adult in a classroom of three- and four-year-olds: you help the lead teacher run activities, supervise small groups, keep records, and support children through meals, transitions and behavior.
There is no single national requirement for the job — state licensing rules apply in centers, state pre-K programs set their own qualifications, Head Start follows a federal minimum for its assistant teachers, and public-school classrooms can add federal Title I paraprofessional rules.
Pre-K assistant teacher duties
The job is support work with a teaching component: the assistant works under the lead teacher's direction, and the pre-K setting gives that support a specific shape.
Pre-K classrooms run in both childcare centers and school systems, and the state-funded part of the field is large — state-funded preschool enrolled nearly 1.8 million children in 2024-25, including 37% of 4-year-olds and 9% of 3-year-olds.
O*NET's task list for childcare workers — the occupation center-based assistant teachers usually fall under — reads like a day in a pre-K room: keeping records on individual children (daily observations, activities, meals served, medications given), dressing children and changing diapers, sanitizing toys, and communicating with parents about daily activities and behaviors.
Where the assistant helps deliver the pre-K curriculum, the day overlaps the work O*NET lists for preschool teachers: teaching basic skills — colors, shapes, numbers, letters, hygiene and social skills — serving meals and snacks per nutritional guidelines, meeting with parents about progress, and maintaining student records.
It is close, physical work.
In O*NET's work-context survey, 83% of childcare workers report constant contact with others and 51% report working very close (near touching) to others.
Centers are usually open year round with long hours, some use full-time and part-time staff on staggered shifts to cover the whole day, and BLS notes that part-time work and irregular hours are common for childcare workers.
NIEER's quality benchmarks describe the room itself: class size of 20 or lower and a staff-child ratio of 1:10 or better.
In 2024-25, 50 of the 63 state-funded pre-K programs met the class-size benchmark and 51 met the ratio benchmark.
For the same role across every age group — infants through school-age — the assistant teacher career guide covers what changes between rooms and what stays the same.
Pre-K assistant teacher requirements
Who sets the bar depends on where the classroom sits.
In a licensed childcare center, the state child care licensing agency writes the assistant's qualifications into licensing rules.
In a state-funded pre-K program, the agency that runs the program sets its own requirements.
In Head Start, a federal rule sets the minimum.
In public-school pre-K, federal Title I rules can apply to paraprofessionals — a different rulebook from the center's.
On the center side, BLS lists a high school diploma or equivalent as the typical entry-level education for childcare workers — a statistical label for the occupation, not a licensing minimum.
Education rules vary by state: BLS notes some states require a high school diploma or equivalent for entry-level positions, while others have no education requirement for entry-level positions.
Beyond education, BLS summarizes what licensure often involves for childcare staff: passing a background check, having a complete record of immunizations and meeting a minimum training requirement, with some states requiring CPR and first aid certification.
Where a state requires a nationally recognized credential for childcare workers, BLS says it is most often the Child Development Associate (CDA), which must be renewed every 3 years.
Head Start sets its own federal floor.
Under 45 CFR 1302.91(e)(3), Head Start Preschool assistant teachers must at minimum have a CDA or a state certificate that meets or exceeds it, be enrolled in an associate or bachelor's program, or be enrolled in a CDA program to be completed within two years of hire.
In state-funded pre-K, assistant qualifications are program rules rather than one national standard.
NIEER tracks a quality benchmark that would require assistant teachers to hold a CDA or equivalent, and 21 of the 63 state-funded programs met that benchmark in 2024-25 — so whether a CDA-level credential is expected depends on the state program you apply to.
In public schools, Title I adds its own qualification layer.
Under 34 CFR 200.58, paraprofessionals in Title I-funded programs must have a high school diploma or equivalent, and those hired after January 8, 2002 also need two years of college, an associate degree or higher, or a passing state or local academic assessment.
The same rule defines a paraprofessional as someone who provides instructional support, and it excludes staff whose duties are only non-instructional, such as personal care or clerical work.
These federal rules cover school programs — not aides in licensed childcare centers, whose requirements come from state licensing instead.
The state-by-state detail for the center tier — minimum ages, education options and training windows — is in the assistant teacher requirements guide.

Pre-K assistant teacher pay
There is no federal pay category for pre-K assistant teachers.
Federal occupation data splits daycare classroom staff across codes, and center-based assistant teachers usually land under childcare workers (SOC 39-9011) — O*NET even lists 'Daycare Teacher', 'Infant Teacher' and 'Toddler Teacher' among that occupation's reported titles.
In May 2025, BLS put the median wage for childcare workers at $34,980 per year, or $16.82 an hour.
The spread was wide: the lowest 10% earned less than $11.66 an hour and the highest 10% earned more than $22.12 an hour — percentiles across a whole occupation, not an entry-level promise.
The employer mattered within the occupation: in May 2025, the median hourly wage for childcare workers was $18.15 in local elementary and secondary schools, $16.43 in child daycare services and $16.23 in religious, grantmaking, civic and similar organizations — the same occupation measured across industries, not different jobs.
State pre-K programs can set their own rates, as two examples from different years show.
Georgia's DECAL funds Georgia Pre-K assistant teachers at $25,741.35 per year in 2026-27, at both private and public providers — assistant pay rose by $5,551 in state fiscal year 2025, when lead teachers moved onto the K-12 salary scale (the current chart is on our Georgia Pre-K teacher salary scale page).
Alabama's First Class Pre-K titles the assistant role 'auxiliary teacher': its most recent published guidelines (2023) list an auxiliary teacher base salary of $22,440 in Appendix A, and programs must pay auxiliary teachers at least the CDA salary.
One number not to use: BLS's separate teacher-assistant occupation (25-9042) is mostly K-12 school staff — 72% worked in local elementary and secondary schools — so its median describes the school paraprofessional job, not a pre-K assistant teacher in a center.
Moving up from pre-K assistant teacher to lead teacher
The CDA is the credential states most often name when they require a nationally recognized one, and the center-based Preschool CDA matches this age band — it covers children ages 3 to 5.
Eligibility starts with a high school diploma or GED — or enrollment as a junior or senior in a high school early childhood education career and technical program.
The credential requires 120 hours of formal early childhood education training, with at least 10 hours in each of the eight CDA subject areas, plus 480 hours of professional work experience with the setting's age group earned within 3 years.
The Council for Professional Recognition charges a $525 online assessment fee for the initial credential.
A CDA is valid for 3 years from the award date, and renewal costs $250.
At the lead step, the occupation — and the pay data — changes: preschool teachers (SOC 25-2011), the occupation O*NET lists 'Pre-Kindergarten Teacher' under, had a May 2025 median annual wage of $38,140.
The requirements depend on the route: BLS says public-school preschool teachers generally need at least a bachelor's degree and must be licensed to teach early childhood education, while in state-funded pre-K the bar varies by program — 30 of the 63 programs met NIEER's benchmark requiring a bachelor's degree for lead teachers in every classroom in 2024-25.
