The ten domains are the backbone of the 2021 AACN Essentials. Each one names a broad area of professional nursing practice and packages a set of competencies that graduates must demonstrate — at Level 1 (entry/BSN) and Level 2 (advanced/master's and DNP). This guide walks through all ten in order, in plain language, with a note on how each typically appears in nursing assignments and capstone work.
How the domains are structured
Each domain contains several competencies, and each competency has measurable sub-competencies written separately for Level 1 and Level 2. You don't demonstrate a whole domain in one assignment — you accumulate evidence across courses. New to the framework? Read the Essentials overview first.
1Knowledge for Nursing Practice
Often called the "discipline" domain, this is about integrating nursing science with knowledge from the arts, humanities, and other sciences to inform practice. It's the foundation the other nine build on. In your capstone, this shows up whenever you ground a clinical problem in theory and established science rather than opinion.
2Person-Centered Care
Care planning and delivery that is grounded in respect for the individual — their values, preferences, family, and culture. Competencies include establishing a caring relationship, performing holistic assessment, and partnering with patients in decisions. A capstone intervention that accounts for patient preferences and shared decision-making is demonstrating this domain.
3Population Health
Working across systems and disciplines to improve health outcomes for groups — communities, panels, and populations. Competencies span community engagement, epidemiology, and addressing social determinants of health. Capstones on screening programs, community education, or readmission reduction lean heavily on this domain.
4Scholarship for the Nursing Discipline
Generating, translating, and applying evidence to advance nursing. This is the research and evidence-based-practice engine of the Essentials. For most students, the capstone is where this domain is demonstrated most visibly — through a literature review, evidence appraisal, and an evidence-based intervention. Our EBP capstone guide goes deeper here.
5Quality and Safety
Employing established and emerging safety science to minimize risk of harm and improve outcomes. Think QI methods, just culture, error reduction, and reliable systems. A capstone tied to a measurable safety or quality metric — falls, CLABSI, readmissions — is squarely in this domain.
6Interprofessional Partnerships
Intentional collaboration across professions to optimize care, including communication, role clarity, and shared decision-making. Capstones that involve coordinating with pharmacy, providers, social work, or therapy demonstrate this domain — name those partnerships explicitly when your rubric expects it.
7Systems-Based Practice
Responding to and leading within complex healthcare systems and microsystems — understanding workflow, resources, costs, and the organizational context of care. Capstone work that considers feasibility, cost, and how a change fits into existing unit workflow is demonstrating systems thinking.
8Informatics and Healthcare Technologies
Using information and communication technologies, and informatics processes, to deliver safe care and support decision-making. EHR use, data extraction for your outcome measure, and technology-enabled interventions all fall here. MSN informatics tracks naturally emphasize this domain — see our informatics capstone guide.
9Professionalism
The formation and cultivation of a sustainable professional nursing identity — accountability, ethical comportment, civility, and adherence to standards. In writing, this surfaces as ethical reasoning, honest representation of evidence, and a professional, accountable tone throughout your project.
10Personal, Professional, and Leadership Development
Participating in activities that support lifelong growth, resilience, well-being, and leadership. Capstones increasingly ask for a reflection on your own development and leadership through the project — that reflection is this domain in action.

Don't confuse domains with concepts
The ten domains are the columns; the eight concepts (clinical judgment, ethics, EBP, SDOH, etc.) are threads that run through all of them. A capstone demonstrates domains and weaves concepts through. See the 8 concepts guide so you don't treat a concept as if it were a domain.

Frequently asked questions
It varies — domains have between three and six competencies, each with multiple Level 1 and Level 2 sub-competencies. The exact counts are published in the AACN Essentials document; for capstone purposes, focus on the domains your rubric emphasizes rather than memorizing every sub-competency.
No. A capstone demonstrates a meaningful cluster — commonly domains 1, 4, 5, and 2, with others appearing depending on topic. Trying to force all ten usually weakens a project. Map to what your rubric asks for.
A competency is the broad ability statement within a domain; sub-competencies are the specific, measurable, level-differentiated behaviors that demonstrate it. Programs assess sub-competencies because they're observable.
Scholarship for the Nursing Discipline (domain 4) and Quality and Safety (domain 5) tend to carry the most weight, because the capstone is fundamentally an evidence-based quality improvement project. But Knowledge for Nursing Practice and Person-Centered Care almost always appear too.
