Becoming a preschool teacher can require as little as a high school diploma and a credential, or as much as a bachelor’s degree and state certification, depending on where you want to work. The path you take hinges mainly on one decision: whether you plan to teach in a private childcare center or a public school prekindergarten program. Here’s what each route looks like, what it costs in time and money, and what you can expect to earn.
Private Centers vs. Public Schools
This distinction matters more than anything else because it determines your education requirements. Private preschools and childcare centers generally operate under state childcare licensing rules, which set minimum qualifications for staff. In many states, you can work as a lead teacher in a private center with a high school diploma or GED plus a nationally recognized credential like the Child Development Associate (CDA). Some states require an associate degree, but a bachelor’s degree is rarely mandatory for private-center roles.
Public school prekindergarten programs are a different story. These are run by school districts and follow the same certification framework as K-12 education. That means you typically need a bachelor’s degree from an accredited university and a state-issued teaching certificate. Many states also require an additional early childhood qualification on top of that certificate, such as a CDA credential, a Montessori certification, or college coursework specifically in early childhood education.
If you’re unsure which setting appeals to you, the private-center route is faster and less expensive to start. You can always go back to school later to qualify for public school positions.
The CDA Credential
The Child Development Associate credential, issued by the Council for Professional Recognition, is the most widely recognized entry-level qualification in early childhood education. It’s often the fastest way to move from “interested” to “employable.”
To be eligible, you need a high school diploma or GED (or current enrollment as a junior or senior in a high school early childhood education program). From there, the process has a few components:
- 120 hours of professional education: Coursework covering eight subject areas, including child development, health and safety, and family communication. Many community colleges and online programs offer CDA training packages.
- 480 hours of work experience: Hands-on time working with children in the age group matching your CDA application. This can come from paid employment, student teaching, or volunteer work at a licensed program.
- A professional portfolio: A collection of your work samples, a competency statement, and family questionnaires gathered from parents of children you’ve worked with.
- A verification visit and exam: A credentialed professional observes you working with children, and you take a standardized exam. You have six months from the date you’re cleared to schedule both, or you risk forfeiting your application fee.
The entire process can take anywhere from a few months to a year, depending on how quickly you complete the training hours and accumulate work experience. The CDA is valid for three years and must be renewed.
Getting a Bachelor’s Degree
If your goal is teaching in a public school pre-K program, you’ll need a bachelor’s degree from an accredited college or university. Most aspiring preschool teachers major in early childhood education, elementary education, or child development, though many states don’t mandate a specific major as long as you complete the required certification process.
A four-year degree program in early childhood education typically includes coursework in child psychology, curriculum design, literacy development, and classroom management. You’ll also complete student teaching placements where you spend weeks or months working in real classrooms under the supervision of a mentor teacher. These placements are where most people figure out their preferred age group and teaching style.
If you already have a bachelor’s degree in another field, you don’t need to earn a second one. Most states offer alternative certification programs that let career changers complete the required education coursework and clinical hours in one to two years while working toward their teaching certificate.
State Teaching Certification
After earning your degree, you’ll apply for a teaching certificate through your state’s education agency. The general process looks similar across the country: submit transcripts, complete a background check, and pass one or more standardized exams covering both content knowledge and teaching skills. Some states issue a provisional or probationary certificate first, then upgrade it to a standard certificate after you complete a year or two of supervised teaching.
For public pre-K specifically, many states layer on an additional qualification beyond the basic certificate. Common options include holding a CDA credential, earning a Montessori certification, completing 15 or more college credit hours in early childhood education, or documenting several years of experience in an accredited childcare program. Check your state education agency’s website for the specific combination your state accepts.
Background Checks and Other Clearances
Federal law requires every staff member in a licensed childcare program to pass state and federal criminal background checks. This applies broadly: teachers, directors, bus drivers, custodians, kitchen staff, and any adult who will have unsupervised access to children.
The checks are thorough. They include a national FBI fingerprint-based criminal history check, a search of the National Sex Offender Registry, and searches of state criminal registries, sex offender databases, and child abuse and neglect registries in every state where you’ve lived in the past five years. Your employer must submit the background check request before you’re officially hired, and checks must be repeated at least once every five years.
Beyond background checks, most employers require current CPR and first aid certification, which you can get through the American Red Cross or similar organizations in a single day. Many states also require a health screening or tuberculosis test before you begin working with children.
Building Experience Before You Apply
Classroom experience makes you a stronger candidate regardless of which path you take. If you’re still in school or working toward your CDA, look for opportunities to log hours with young children. Volunteering at a licensed childcare center, working as a teacher’s aide, or assisting in a church or community preschool program all count. Summer camp counselor roles and after-school program positions also give you relevant experience.
Many private preschools hire assistant teachers with minimal qualifications and support them in earning credentials on the job. Starting as an assistant lets you accumulate the 480 hours of work experience required for the CDA while earning a paycheck. Some larger childcare organizations even cover part of the cost of CDA training or college tuition as an employee benefit.
What Preschool Teachers Earn
The median annual wage for preschool teachers was $37,120 in May 2024, according to the Bureau of Labor Statistics. The lowest 10 percent earned less than $28,300, while the highest 10 percent earned more than $60,070. Pay varies significantly based on setting: public school pre-K teachers who hold a bachelor’s degree and state certification generally land on the higher end, while private childcare center teachers tend to earn less.
Employment in this field is projected to grow 4 percent from 2024 to 2034, roughly matching the average for all occupations. About 65,500 openings are projected each year over that decade, driven largely by turnover as teachers retire or move into other education roles. Demand is particularly strong in areas with expanding state-funded pre-K programs.
Choosing Your Path
Your timeline and budget should guide which route you take. If you want to start working with children quickly, pursue the CDA credential. You can be job-ready in under a year with a modest investment in training. If you want higher pay, more job security, and access to public school positions, plan for a four-year degree and state certification. Many teachers do both: they start in a private center with a CDA, then go back to school part-time while working.
Whichever route you choose, the core requirements are the same: you need formal training in child development, real experience working with young children, and the ability to clear a comprehensive background check. Everything else is a matter of how far you want to go.
