Though requirements vary by state, all U.S. states require public school teachers to be licensed. All states require either a bachelor’s degree or the completion of an approved training/academic program. Teachers must also have a specific number of subject and education credits, along with supervised practice teaching experience.

Some teaching jobs may require a more specialized degree, such as a master’s or PhD. The requirements for private school teachers, college professors, and university professors vary depending upon the school, but many of these schools have similar and in some cases, stricter requirements.

The licensing requirements for preschool teachers also tend to vary by state. Certifications from a recognized authority, an associate’s degree, or a bachelor’s degree are the most common requirements.

The State Board of Education or a licensure advisory committee grants licenses to teachers. Aspiring teachers are tested on their knowledge of basic teaching skills, reading, and writing. Teachers who are subject based are often required to demonstrate proficiency in their subject or field.

In some states, alternative licensure programs are available to teachers who have a bachelor’s degree in a certain subject, but lack other requirements that are required for a regular teaching license.
