Navigating the various professional credentials required for educators can be complex, especially when planning for career advancement or meeting specific state requirements. Understanding how different authorizations function is a crucial step in becoming a teacher and continuing to grow within the profession. Whether you are looking to teach a new content area, are moving to a new state, or stepping into specialized roles, educator credentials can have legal and professional implications. This post will outline the primary differences between licenses, certificates, and endorsements, and explain the pathways for adding qualifications to an existing teaching credential.
Key Takeaways
- Licensure is the legal authorization to teach in public schools; certification is the term some states use interchangeably for that authorization, though terminology and meaning vary by state1
- A teaching licensure endorsement is an added subject, grade-level, or specialty authorization that attaches to an existing teaching credential2
- Adding licensure endorsements in high-need areas such as special education or ESL helps fill critical staffing gaps in school districts3
- Educators can often add licensure endorsements by passing the appropriate content exams, though specialized areas require approved university coursework4
- A licensure endorsement is distinct from a specialty license or standalone credential. An endorsement specifically adds authorization to an existing base license, rather than serving as an independent credential.
What is the difference between teacher certification and licensure?
The difference between teacher certification and licensure is mostly in the terms themselves as both serve as baseline requirements for classroom teaching. Licensure is the formal, legal state authorization required to teach in public schools. Certification is often the term that many state boards of education use for this same authorization, though in some states the two terms carry distinct meanings. Because each state or jurisdiction is responsible for establishing its own rules, the exact terminology and legal meanings will vary depending on where you teach.
It is also worth noting that private schools may have different credentialing requirements than public schools and may not require state licensure or certification.
It is possible to obtain a teaching certification entirely online, but some states require that an individual hold a license from the state in which they completed their educator preparation program before they will issue a new license.⁵ For public school teaching, passing required subject-area exams and meeting formal regulatory thresholds are essential steps for licensure.⁵
What are teaching licensure endorsements?
If you are wondering what teaching licensure endorsements are, they are specific authorizations added to a teacher's existing credential. Washington's Professional Educator Standards Board defines a licensure endorsement as the specific subject matter or content area listed on a teaching certificate.² In addition, the District of Columbia explains that an added licensure endorsement allows an educator to demonstrate qualifications in an additional subject area.⁶
For example, a licensure endorsement typically appears on a teaching certificate as a designated subject area or grade band (such as "Mathematics 6–12" or "English as a Second Language K–12") that specifies what the educator is authorized to teach.
When comparing a base license vs. a licensure endorsement, the base license allows an individual to enter the classroom, while a licensure endorsement expands an educator's authorized scope of practice. In jurisdictions such as the District of Columbia, only individuals who hold an active primary standalone teaching credential are eligible to earn a teaching licensure endorsement.⁶ Once licensed, teachers may pursue add-on pathways to increase their versatility and expertise.⁵
What licensure endorsements can you add to your teaching certificate?
Teaching certificate endorsement options often reflect state-specific demand and critical educational needs. Common examples of add-on licensure endorsements include special education, English as a second language (ESL), and reading specialist designations, though availability and classification vary by state. In Kansas, educators can pursue program-completion areas such as the high incidence disabilities licensure endorsement or the building leadership licensure endorsement.⁴
High-need teaching licensure endorsements align directly with real staffing gaps. According to the National Center for Education Statistics (NCES) School Pulse Panel survey of public school principals for the 2024–25 school year, 74% of elementary and middle schools reported difficulty filling special education vacancies with a fully certified teacher (defined as holding full state certification in the relevant field).³ Further, 69% of high schools in the same survey experienced challenges filling ESL and bilingual vacancies.³ Literacy-related licensure endorsements remain highly relevant as well, with reading specialists in demand to help improve student reading proficiency as measured by national assessments such as NAEP.⁷
These specializations may also impact earning potential, though actual salaries vary significantly by location, experience, and employer. According to the Bureau of Labor Statistics (BLS), special education teachers earned a median annual wage of approximately $64,270 as of May 2024, while ESL teachers and reading specialists typically fall within similar ranges depending on their role and district.⁸
How to add a licensure endorsement to a teaching license
To figure out how to add a licensure endorsement to a teaching license, you need to first review state-specific requirements. In many cases, adding a licensure endorsement is a more streamlined process than earning initial licensure or certification. In Kansas, educators holding an active initial or professional teaching license can add most teaching licensure endorsements by receiving a passing score on the appropriate Praxis content exam and submitting an added endorsement application.⁴
However, specific specialized fields require more than just a test. Licensure endorsements in areas such as ESOL, special education, reading specialist, and building leadership require approved program completion.⁴ This involves specialized university coursework and supervised practicum experiences alongside passing the required state assessments. For example, as of 2025, adding a TESOL licensure endorsement in Kansas requires both the subject exam and two specific courses.⁵ Because rules differ by jurisdiction, educators should always verify current requirements with their local state office.

The online KU programs meet the educational requirements for licensure endorsement in the state of Kansas if the candidate already holds an initial or professional teaching license. None of the KU online programs lead to initial licensure.
KU’s licensure programs strive to maintain accurate and up-to-date information about the educational requirements for licensure in U.S. states and territories. However, regulations are subject to change and varying interpretations. In addition to possible changes in educational requirements, licensure often includes additional requirements, such as specific examinations and additional training or practicum hours. It is highly recommended that students seek guidance from the appropriate licensing agency before beginning an academic program to ensure they know what is needed to obtain the license/certification/registration in the state in which they intend to practice and/or seek licensure.
