Contact your state's department of education, either online or over the phone. Ask about certification or licensing requirements to become a preschool teacher. Some states may require a Child Development Associate (CDA) certification, obtained at a community college or university, while others may require an associate's or bachelor's degree.
Obtain the necessary credentials to receive a preschool teaching license. You may need to attend cardiopulmonary resuscitation (CPR) or first-aid courses. Depending on your state of residency, you may also need to attend early education certification courses from the Department of Education.
Contact your state's Department of Human Services for information on how to open a child care facility in your home. You may need to contact the state's child care licensing center directly to find out more information. Fill out all necessary applications and paperwork and pay the required fees. After you receive your license, you may operate a preschool early learning center in your home.
