What Is Evaluation as a Field, and What Do Evaluators Do?

Evaluation is the systematic process of judging the merit, worth, and significance of programs, personnel, policies, and other interventions—and evaluators are the professionals who design and carry out that judgment. The American Evaluation Association (AEA), whose site is eval.org, describes the field as spanning "program evaluation, personnel evaluation, technology, and many other forms of evaluation." If you are considering evaluation as a career or trying to understand what an evaluator actually contributes, the practical answer is that evaluators turn questions like "Did this work?" and "Was it worth it?" into evidence-based findings that funders, organizations, and communities can act on.

What evaluation covers

Evaluation is broader than a single method or sector. AEA's own description names several distinct strands:

• Program evaluation — assessing whether a program, initiative, or intervention achieved its intended outcomes and how it could improve.
• Personnel evaluation — appraising individual performance within organizations.
• Technology evaluation — judging tools, systems, and technical interventions.
• Other forms of evaluation — the field deliberately stays open to new domains rather than restricting itself to a fixed list.

What ties these together is a disciplined process: defining what success means, gathering credible evidence, and interpreting that evidence so decisions can be made. Evaluators work across nonprofits, government, education, health, and international development, which is why AEA frames the field around "application and exploration" rather than one narrow job description.

What evaluators actually do

Day to day, evaluation work tends to follow a recognizable arc, even though specific tasks vary by project:

1. Frame the question. Clarify what is being evaluated and what "good" would look like—often by working with stakeholders to define outcomes and criteria.
2. Design the approach. Choose methods (surveys, interviews, administrative data, observation, mixed methods) that fit the question and the context.
3. Collect and analyze evidence. Gather data responsibly and interpret it, including attention to who is affected and how.
4. Report and support use. Communicate findings in ways that stakeholders can understand and act on.

The judgment at the center of this work is what distinguishes evaluation from pure research: evaluation exists to inform decisions about a specific program or practice, not only to produce general knowledge.

The competencies and standards behind the work

AEA publishes Evaluator Competencies and a Cultural Competence Statement, which together signal what the field expects of practitioners. The competencies describe the knowledge and skills evaluators are expected to demonstrate; the cultural competence statement addresses how context, identity, and equity shape sound evaluation practice. AEA also maintains policies and guiding principles that govern how its members conduct themselves.

For anyone entering the field, these documents are the closest thing to a shared professional baseline—useful for self-assessment, for hiring, and for understanding what "good evaluation" means beyond any single project.

How to learn evaluation and build a career path

AEA positions itself as a learning hub as well as a professional association. Its education offerings include:

Beyond courses, the career side runs through AEA's Career Center, EvalTalk (the field's discussion community), Topical Interest Groups (TIGs) for specialty areas, local affiliates, and a Find an Evaluator directory that shows how practitioners present themselves professionally. AEA also holds two in-person events each year, which it describes as serving evaluators "of all level."

Choosing whether this field fits you

Evaluation suits people who like combining analytical rigor with real-world decisions and who are comfortable working with diverse stakeholders—AEA explicitly aims to be "an inclusive and diverse environment where evaluators can learn and connect regardless of experience in the field." If you want a low-commitment first step, start with Eval 101 or a Coffee Break; if you are a graduate student or at an MSI, look at the GEDI and MSI fellowship pathways; if you are hiring, the Find an Evaluator directory and the Competencies are the practical starting points. Membership and program details, including any costs, are best confirmed directly on eval.org, since the site's public pages describe offerings without listing prices.
