NBCT key terms

Independent nonprofit that sets advanced teaching standards and administers National Board Certification. It defines certificate areas, develops standards, and oversees the scoring of candidate evidence.

Five foundational statements describing what accomplished teachers should know and do: commitment to students, knowledge of subjects, managing learning, thinking systematically, and membership in learning communities. They underpin all certification components.

Detailed descriptions of accomplished practice for each certificate area, developed by teachers and experts. They define what candidates must demonstrate and guide portfolio and assessment expectations.

The specific subject and developmental level for which a candidate seeks certification, such as Early Childhood Generalist or Adolescent Mathematics. Each area has its own standards and Component 1 assessment.

Computer-based assessment of a candidate's subject-matter and pedagogical content knowledge, including selected-response and constructed-response items. It is scored against national standards for the certificate area.

An assessment item requiring a written, extended answer rather than selection from options. In Component 1, candidates explain content and instructional reasoning in their certificate area.

A multiple-choice or similar item where the candidate chooses the best answer from provided options. Component 1 uses these to sample breadth of content knowledge.

Understanding of how to teach a specific subject, including common misconceptions, representations, and strategies that make content learnable. It bridges subject expertise and classroom practice.

Deep understanding of the subject matter a candidate teaches, including facts, concepts, structures, and modes of inquiry. It is a foundation for Component 1 and accomplished practice.

Practice that meets the National Board Standards by advancing student learning, using evidence, and reflecting on effectiveness. It is the target of all four components.

Portfolio component where candidates submit evidence of planning and implementing instruction tailored to students' needs, strengths, and learning profiles, with analysis of student work.

Purposefully adapting content, process, product, or environment based on student readiness, interests, and learning profiles. It aims to ensure each student has appropriate challenge and support.

Understanding of students' academic strengths, cultural backgrounds, interests, language needs, and learning differences. Candidates use this to plan responsive instruction and justify differentiation choices.

The description of the classroom setting, student population, curriculum, and constraints that shapes instructional decisions. Candidates explain context to show why choices are appropriate.

A summary of an individual student's strengths, needs, prior knowledge, interests, and language or learning supports. It informs differentiation and assessment planning.

A change in how a student accesses instruction or assessment without altering learning expectations, such as extended time or preferential seating. It removes barriers while preserving standards.

A change to the content, expectations, or rigor of an assignment or assessment for a student with identified needs. It alters what the student is expected to learn or demonstrate.

Ongoing checks for understanding used to adjust teaching and provide feedback during learning. It is low-stakes and informs next instructional steps.

Evaluation of student learning at the end of a unit or period, used to measure achievement against standards. Results may inform future planning but are not used to adjust the just-completed instruction.

Systematic examination of student products or responses to identify patterns, misconceptions, and evidence of learning. Candidates use it to justify instructional decisions and differentiation.

Portfolio component requiring video recordings of teaching and written commentary. Candidates demonstrate how they engage students, manage the classroom, and create a productive learning environment.

Unedited footage of the candidate teaching a lesson, submitted as evidence of practice. It is analyzed in commentary to show instructional decisions and student interactions.

Written explanation accompanying portfolio evidence, where candidates describe, analyze, and reflect on their instructional choices and their impact on students. It connects evidence to standards.

A document or product submitted as evidence, such as a lesson plan, student work sample, or assessment. Artifacts are explained and analyzed in commentary.

The physical, social, and emotional conditions in which learning occurs, including routines, relationships, and safety. Candidates show how they build a respectful, engaging classroom.

The shared norms, expectations, and relationships that shape how students interact and learn. A positive culture supports respect, risk-taking, and student ownership.

The degree to which students actively participate in and invest in learning tasks. Candidates demonstrate strategies that sustain attention, curiosity, and persistence.

Deliberate methods a teacher uses to deliver content and facilitate learning, such as questioning, modeling, grouping, or discussion. Candidates justify choices based on content and students.

Portfolio component where candidates document their impact on student learning and their professional growth, collaboration, and leadership over time. It emphasizes analysis and evidence.

Habit of examining one's own teaching, student evidence, and outcomes to identify strengths and areas for improvement. It leads to intentional changes in instruction.

Sustained, job-embedded learning that improves teaching practice, such as study groups, coaching, coursework, or collaborative inquiry. Candidates show how it changed their practice and student outcomes.

A collaborative team of educators who regularly examine data and practice to improve student learning. Membership supports shared responsibility and continuous improvement.

Working with colleagues, families, or community partners to plan instruction, solve problems, and support students. Candidates document how collaboration improved practice or outcomes.

Evidence that teaching practices or professional actions led to measurable or observable student growth. Candidates use multiple sources of data to demonstrate and analyze impact.

Using student assessment and other data to identify needs, adjust instruction, and monitor progress. It is central to demonstrating impact and reflective practice.

Speaking up for students, the profession, or equitable policies, often through collaboration with families, colleagues, or community. Candidates may document advocacy as part of accomplished practice.

A trained mentor who guides National Board candidates through the process, offering feedback and encouragement without doing the work for them.

A group of candidates who progress through the certification process together, sharing feedback and support. Cohorts can improve completion and reflection.

Periodic process by which National Board Certified Teachers demonstrate continued accomplished practice and professional growth to maintain certification. It typically involves reflection on impact.

A set of criteria and performance levels used by trained assessors to evaluate portfolio entries and assessment responses. Rubrics describe evidence of accomplished practice.
