You become a Head Start teacher by meeting the qualification the Head Start Program Performance Standards set for Head Start preschool center-based teachers — at least an associate or bachelor's degree in child development or early childhood education, equivalent coursework, or the alternative in Head Start Act §648A(a)(3)(B) — then adding the background-check, health and training items states often require of childcare staff.
Assistant teacher roles carry a lower floor and are a route in for teachers still working toward the teacher qualification.
What do you need to become a Head Start teacher?
The qualification floor comes from the Office of Head Start, not from a state teaching license — though state licensing rules can also reach Head Start staff, as Step 1 covers.
Under the Head Start Program Performance Standards (45 CFR 1302.91(e)(2)), every Head Start preschool center-based teacher must have at least an associate or bachelor's degree in child development or early childhood education, equivalent coursework, or otherwise meet the alternative in section 648A(a)(3)(B) of the Head Start Act.
One figure gets misread more than any other here.
The standards also require that at least 50% of Head Start preschool teachers nationwide hold a baccalaureate degree in child development, early childhood education or equivalent coursework — a national target measured across programs, not a rule that each individual teacher needs one.
What the workforce actually holds, per federal program data for 2023-24 — 94% of Head Start preschool center-based teachers had an associate degree or higher in early childhood education or a related field, and 56% had a bachelor's degree.
The floor for assistant teachers is lower, and it matters for the route: an assistant teacher must at minimum hold 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.
That enrollment option is what lets you take a Head Start classroom job while you are still working toward the teacher qualification.
The rulebook is also mid-rewrite.
On August 7, 2026, ACF published a proposed rule ("Reducing Federal Burden for Head Start Programs") that would rescind and replace the Head Start Program Performance Standards; comments were due October 6, 2026, and it is a proposal, not final.
It would drop staff qualification rules that go beyond the statute, while the statutory qualifications for preschool teachers, assistant teachers and Early Head Start center-based teachers would remain.
Everything on this page is written to the standards as they stand in October 2026.
For the role itself — duties, settings and how Head Start differs from other preschool jobs — see the Head Start teacher career guide.
This page stays on the entry path.
Step 1: Meet the minimum age, education and health/background requirements
The degree floor is federal, but it is not the only list that reaches you.
BLS notes that to qualify for licensure, childcare staff often must pass a background check, have a complete record of immunizations and meet a minimum training requirement — and that some states require staff to hold CPR and first aid certification.
Those items are written and revised by state child care licensing agencies, so confirm which of them apply to your role with your state's agency — and ask the hiring program what its own screening adds — before you pay for anything.
Minimum age has the same split.
Federal child labor law sets no hour limits for 16- and 17-year-olds in non-hazardous work, while 14- and 15-year-olds are limited to no more than 3 hours on a school day and 18 hours in a school week.
State child labor laws can be stricter, and the age at which a state counts someone as classroom staff is a licensing question of its own — so the working answer on age, like everything else in this step, comes from your state's child care licensing agency.
The education sequence starts earlier than the degree.
The CDA — the credential sitting at the assistant-teacher floor — requires a high school diploma or GED, or enrollment as a junior or senior in a high school early childhood education career and technical program.
From there the two tracks run in parallel: coursework toward the associate or bachelor's degree the teacher rule names, and classroom hours toward the credential.
Confirm both rulebooks before you rely on either
Step 2: Get the credential or coursework your state and employer expect
The teacher rule names three ways to meet the floor: an associate or bachelor's degree in child development or early childhood education, equivalent coursework, or otherwise meeting section 648A(a)(3)(B) of the Head Start Act.
If you already hold college credits, ask the hiring program how it documents the equivalent-coursework route before you count them — that question belongs to the program doing the hiring.
For the assistant floor, and as coursework in its own right, the credential to know is the Child Development Associate (CDA), issued by the Council for Professional Recognition.
Where a state requires a nationally recognized credential for childcare staff, BLS reports that the credential is most often the CDA, and that it must be renewed every 3 years.
The Council's requirements are concrete:
- Hold a high school diploma or GED — or be enrolled as a junior or senior in a high school early childhood education career and technical program
- Complete 120 hours of formal early childhood education training, with at least 10 hours in each of the eight CDA subject areas
- Log 480 hours of professional work experience with the setting's age group, earned within the 3 years before you apply
State expectations can stack on top of the Head Start floor, and they vary — the state child care licensing agency's current staff rules are the list that counts for your role, and the postings for the jobs you want show what individual programs ask for above it.
Then track the proposal, not rumors of it.
Under the August 2026 NPRM, Head Start programs could no longer require or incentivize postsecondary credits, hours or credentials unless they can demonstrate the education is necessary for the position, and hiring would lean on alternatives such as assessments, industry credentials or work experience.
That would change what programs may ask for — but comments were due October 6, 2026 and it is not final, so plan around the current rule and check its status before you enroll in anything.
Step 3: Complete required pre-service training
Once you are on staff, the Head Start standards carry their own training clock: staff must complete at least 15 clock hours of professional development per year, plus annual mandated-reporter training and annual training on positive social-emotional strategies (45 CFR 1302.92).
The 15-hour floor is the durable number on this step.
It sits in the Head Start Act itself (section 648A(a)(5)), which is why the August 2026 proposal — for all it would trim from the standards — states that programs must continue to ensure each classroom teacher completes at least 15 clock hours of professional development annually.
What happens before your first solo day is a different ledger.
The qualification rule sets what you must have; pre-service orientation is arranged by the hiring program, and state training rules may add their own pre-service hours.
Our research carries no single national pre-service hour figure, so ask the program what it requires before day one and confirm the current hours with your state's child care licensing agency.
Step 4: Gain classroom experience (aide, assistant, sub, practicum)
Experience is not just resume-building here — it is built into the credential math.
The CDA counts 480 hours of professional work experience with the setting's age group, earned within the 3 years before you apply.
Assistant, aide, floater and substitute work all put you in a classroom with an age group, and the hours you log with the credential's age group are what the Council counts.
A practicum placement through a degree or CDA program can add structured classroom time; ask the Council how a specific placement counts before you rely on it.
The assistant teacher role is also the on-ramp the Head Start rule itself builds: the floor accepts a CDA, a state certificate that meets or exceeds it, enrollment in an associate or bachelor's program, or enrollment in a CDA program to be completed within two years of hire.
Working as an assistant while enrolled is how the experience hours and the credential get earned at the same time.
Know the classroom you are walking into.
Current standards cap a class with a majority of 4- and 5-year-olds at 20 children with a teacher and a teaching assistant, or two teachers (17 in a double-session arrangement); a class with a majority of 3-year-olds is capped at 17 (15 in double session).
The proposed rule would replace the federal ratio and group-size limits with state-established standards, so treat those figures as current as of October 2026 and check with the hiring program.
Step 5: Apply for Head Start teacher jobs
The workforce you are applying into is countable: Head Start employed and contracted with about 251,000 staff in 2023-24, and parents of current or former Head Start children made up 24% of them.
About 112,000 of those staff provided child development services — teachers, assistant teachers, home visitors and family child care providers — and 31% of them were proficient in a language other than English.
The children served shape what programs look for.
About 35% of children enrolled in Head Start were dual language learners in 2023-24, and 63% of those were in families that primarily spoke Spanish at home.
If you speak a language other than English, that skill speaks directly to the population these classrooms serve.
Make the application easy to verify.
List your degree status or enrollment, your CDA status if you hold or are pursuing one, your experience hours by age group, and any state-required training or certification.
Then browse Head Start teacher jobs to see what programs near you are asking for — postings are the employer-side version of everything in this guide.
How long does it take?
There is no fixed timeline, because the path runs on hours and credits rather than a program length.
The teacher floor is an associate or bachelor's degree, equivalent coursework or the statutory alternative, so the honest answer depends on how many credits you already hold and how many you can carry a term.
The assistant route runs on hours you can earn while employed: 120 training hours plus 480 experience hours with the age group — experience counts if it falls in the 3 years before you apply — and a Head Start program can hire you as an assistant while you are still enrolled, with the CDA to be completed within two years of hire.
How fast this route moves is mostly a function of how many classroom hours a week you work.
The requirements do not stop at hire: the 15 clock hours of annual professional development, the annual mandated-reporter training and the annual social-emotional training continue every year you teach.
And the rulebook itself is in motion — the August 2026 proposal to rescind and replace the standards is not final, so re-check the qualification rule before you build a plan around any single figure on this page.
Career information, not licensing or legal advice — Head Start qualifications are set by the Office of Head Start under 45 CFR 1302.91, and staff licensing conditions by each state's child care licensing agency. Confirm current requirements with both before you make a decision that depends on them.
