ExploreAbout this exam
National Board Certification is the professional certification that the National Board for Professional Teaching Standards (NBPTS) describes as the highest certification a teacher may obtain and the most respected one in education. It was designed to develop, retain and recognize accomplished teachers and to generate ongoing improvement in schools nationwide, and more than 146,000 teachers have achieved it. Candidates complete four components in all 25 certificate areas, and the specific instructions and the standards assessed vary by certificate area. Component 1 is a computer-based assessment, delivered through Pearson VUE, made up of three constructed response exercises and 45 selected response items covering content knowledge and pedagogical practice across the full age and ability range of your certificate. Components 2, 3 and 4 are classroom-based portfolio entries submitted through the ePortfolio system: differentiation in instruction with student work samples and written commentary, teaching practice and learning environment with video recordings and commentary, and evidence of yourself as an effective and reflective practitioner. Scoring is standards-based: your score reflects how clearly and consistently assessors located convincing evidence that you met the National Board Standards for your field. Preparation therefore centers on the Five Core Propositions, your certificate-specific standards, and each component's instructions.
What you'll study
About NBCT preparation
What is National Board Certification, in plain terms?
It is the certification NBPTS calls the highest a teacher may obtain and the most respected in education, designed to develop, retain and recognize accomplished teachers and to generate ongoing improvement in schools nationwide. It is a standards-based assessment: your score reflects how clearly and consistently assessors found convincing evidence that you met the Standards for your certificate field.
How many components are there, and is the structure the same for everyone?
Candidates in all 25 certificate areas complete four components. The specific instructions vary by certificate area, and so do the standards each component assesses, so work from the instructions and standards published for your own field rather than borrowing materials from a colleague in a different certificate area.
What should I expect from Component 1?
It is a computer-based assessment delivered through Pearson VUE at test centers across the United States. You demonstrate content knowledge and pedagogical practice for your content area, including developmentally appropriate content needed to teach across the full age range and ability level of your certificate. It consists of three constructed response exercises and 45 selected response items.
Where do I submit the portfolio components?
Through ePortfolio, the National Board's electronic portfolio submission system, which candidates use to compile and submit materials for evaluation. Component 1 is the exception: it is taken as an online assessment delivered by Pearson VUE, not submitted as a portfolio.
How is a certification decision reached, and what score do I need?
NBPTS describes certification as standards-based, and your score reflects the degree to which assessors were able to locate clear, consistent, and convincing evidence that you met the Standards specific to your certificate field. The public pages summarized here do not publish a passing score, so confirm the current requirement in your official candidate materials.
What do fees, retakes, and validity periods look like?
Those details are not stated on the NBPTS pages summarized here, so we do not estimate them. Check the Paying for Certification area and the official candidate policy and procedure documents on nbpts.org before you budget, schedule a retake, or plan around a validity window.
Do I have to complete the four components in a particular order?
The component pages describe what each component requires but do not set a required sequence; what they do make clear is that a certification decision comes after scores on all four components. A practical approach is to start with the component whose evidence you can gather soonest in your school year.
What is the most common way candidates lose points in the portfolio entries?
Commentary that only describes. Component 2 asks you to analyze your instructional choices; Component 3 asks you to describe, analyze and reflect on your teaching and interactions; Component 4 asks for evidence of how you use assessment and collaborate. Match each artifact and each paragraph to the specific demand being assessed.
How should I organize my preparation?
Read the Five Core Propositions and the Standards for your certificate first, then your component instructions, since the standards assessed differ by component. Practice writing short analytic commentary on your own lessons, and collect student work and video early so you select evidence deliberately rather than at the deadline.
Is this guide affiliated with NBPTS?
No. This is independent study material written for exam preparation. It is not produced, reviewed, endorsed, or sponsored by the National Board for Professional Teaching Standards, and it does not reproduce official candidate materials.
