Learn About National Board Teaching Certification

What Is National Board Certification for Teachers?

National Board Certification is a voluntary credential that teachers can pursue to demonstrate advanced knowledge and skills in their subject area and grade level. Unlike state teaching licenses, which are required to teach in public schools, National Board Certification represents an achievement beyond basic licensure requirements. The National Board for Professional Teaching Standards (NBPTS), an independent nonprofit organization, administers this certification process.

The certification system began in 1989 and has grown significantly over the decades. As of 2023, more than 130,000 teachers across the United States hold National Board Certification. These teachers work in public schools, charter schools, and other educational settings. The certification covers numerous subject areas, including elementary education, mathematics, science, English language arts, social studies, and specialty areas like special education and English as a new language.

National Board Certification focuses on what experienced teachers should know and be able to do. The certification recognizes teachers who meet high standards in their field. Teachers who pursue this credential must demonstrate their teaching ability through multiple assessment methods, including portfolio entries, video recordings of classroom instruction, and written exams. The entire process typically takes one to three years to complete, depending on how quickly a teacher gathers required materials and completes assessments.

Many states and school districts offer financial incentives for teachers who obtain National Board Certification. These incentives vary widely by location. Some states provide one-time bonuses, while others offer annual salary supplements. A few states have reduced their incentive programs in recent years due to budget constraints, so the landscape of support continues to change. Teachers interested in pursuing this credential should research what support may be available in their state or district.

Practical Takeaway: National Board Certification is a professional achievement that goes beyond basic teaching credentials and is pursued by teachers who want to demonstrate advanced expertise in their field. Understanding what this certification represents helps teachers decide whether pursuing it aligns with their career goals.

Who Can Pursue National Board Certification?

To pursue National Board Certification, teachers must meet several baseline requirements set by the National Board for Professional Teaching Standards. The primary requirement is that a teacher holds a valid state teaching license or credential in the subject area and grade level they wish to certify in. Teachers cannot use National Board Certification to replace state licensure—the two credentials serve different purposes and work together.

Teachers must also have completed at least three years of full-time teaching experience in a public or private school setting by the time they submit their portfolio materials. This experience requirement ensures that candidates have substantial classroom practice before seeking advanced certification. Some teachers complete their three years of teaching and then immediately begin the certification process, while others wait longer into their careers to pursue it.

The teaching experience must be in the subject area and grade level for which the teacher is seeking certification. For example, a teacher who spent three years teaching fifth-grade mathematics can pursue National Board Certification in elementary mathematics, but their experience would not count toward certification in high school physics or English language arts. Teachers who have taught in multiple subject areas or grade levels may need to choose which certification pathway makes most sense for their background.

There is no upper age limit for pursuing National Board Certification. Teachers at any stage of their career—whether they have four years of experience or thirty—may pursue this credential. Some teachers pursue it early in their careers to establish themselves as advanced practitioners, while others pursue it later as a capstone to their professional development. The National Board does not require teachers to have a bachelor's degree beyond what their state teaching license requires, though most teachers in the United States already hold bachelor's degrees.

Practical Takeaway: The main requirements for pursuing National Board Certification are holding a valid state teaching license and having three years of full-time teaching experience in the subject area you plan to certify in. Knowing whether you meet these requirements is the first step in considering this credential.

How the Certification Process Works

The National Board Certification process consists of four portfolio entries and a content exam. Teachers complete this work within a single certification year, which typically runs from September through March. The portfolio entries make up the largest portion of the assessment, accounting for approximately 60 percent of the overall score, while the content exam accounts for approximately 40 percent.

Each portfolio entry asks teachers to document and reflect on their teaching practice. Teachers must submit video recordings of their actual classroom instruction, samples of student work, lesson plans, and written reflections explaining their teaching decisions. The portfolio entries are designed to show how teachers plan instruction, implement strategies in the classroom, and assess student learning. Most portfolio entries focus on specific lessons or units that the teacher selects and documents. For example, a middle school science teacher might record a two-week unit on ecosystems and submit student work samples from that unit along with a detailed written reflection on how students progressed and what instructional adjustments were made.

The content exam is a computer-based test covering subject-specific knowledge. Teachers register for this exam and take it at a testing center on a scheduled date. The exam varies by certification area. An elementary teacher's exam focuses on reading, writing, and mathematics across the elementary grades, while a high school English teacher's exam focuses on literature, writing, and language across the secondary grades. Teachers receive scores that indicate whether they performed at the proficient level or above.

Teachers work through the certification process at their own pace within the certification year. Some teachers dedicate significant time over several months, gathering videos and student work samples and writing reflections. Others compress the process into a shorter timeframe. The National Board provides a portfolio guide and scoring rubrics for each certification area so teachers know exactly what evidence is needed and how their work will be evaluated. Teachers can review sample portfolios from teachers who previously earned certification to understand the standards and quality expected.

Practical Takeaway: The certification process requires teachers to document their teaching through portfolio entries and pass a content exam. Understanding the structure and requirements helps teachers plan their preparation timeline and gather necessary materials systematically.

What National Board Certification Costs and Support Available

The cost to pursue National Board Certification varies based on which certification area a teacher selects and includes several components. As of 2024, the portfolio submission fee is $500, and the content exam fee is $400, totaling $900 before any discounts or subsidies. Some teachers may pay slightly different amounts depending on their specific certification pathway, as certain specialty areas have slightly different fee structures.

Many states and local school districts offer financial support to help teachers cover these costs. According to data from the National Board, approximately 40 states have some form of financial incentive program for teachers pursuing or holding National Board Certification. These programs vary significantly in scope. Some states reimburse teachers for the full cost of pursuing certification, some provide partial reimbursement, and some provide bonuses only after the teacher earns certification. Teachers should contact their school district's human resources office or their state department of education to learn what support may be available in their location.

Beyond the direct assessment fees, teachers often invest in preparation resources. Some teachers purchase study guides or take preparation courses offered by educational organizations or universities. The cost of these additional resources ranges from free online materials to several hundred dollars for comprehensive preparation programs. Some school districts provide preparation support as part of their professional development offerings at no cost to teachers. Teachers should ask their district whether any preparation resources are available through the school or district before purchasing materials independently.

In states with robust support programs, teachers may pay little to nothing out of pocket for pursuing National Board Certification. However, in states with limited or no financial support, teachers bear the full cost themselves. The financial landscape for National Board incentives has shifted over time, with some states increasing support and others reducing it. Teachers considering this investment should research current programs in their area and consider both the pursuit costs and any ongoing compensation changes that might result from earning certification.

Practical Takeaway: National Board Certification costs approximately $900 in direct fees, but many states and districts offer financial support that can reduce or eliminate this cost for teachers. Investigating what support is available in your location should be part of your initial planning.

Standards and What They Measure

National Board Certification is built on five core propositions that outline what accomplished teachers should know and do. These propositions emphasize that accomplished teachers are committed to students and their learning, know the subjects they teach and how to teach those subjects to students, are responsible for managing and monitoring student learning, think systematically about their practice and learn from experience, and are members of learning communities. These core values shape every certification area and every portfolio entry.

Within each specific certification area, the National Board defines detailed standards that break down what teachers should demonstrate. For elementary teachers, standards address how
