What Is Professional Development? A Practical Guide for K–12 Schools

Professional development is structured learning that helps people strengthen the knowledge, skills, judgment, and practices they use in their work. In K–12 education, it includes the learning teachers, principals, instructional coaches, paraprofessionals, specialized support staff, and other school leaders undertake to improve their professional practice and support students.

A conference session or one-day workshop can be part of professional development, but attendance alone does not guarantee meaningful learning. Strong professional development connects to a defined need, gives educators opportunities to learn and apply a practice, supports implementation over time, and uses evidence to determine whether anything changed.

This guide explains what professional development means in schools, what it can look like, how it differs from related terms, and how leaders can evaluate whether a proposed activity is likely to be useful.

What does professional development mean in education?

In everyday use, professional development is an umbrella term for organized learning related to a person's work. It may include courses, workshops, coaching, collaborative inquiry, conferences, certifications, mentoring, or independent study.

In U.S. federal education law, the definition is more demanding. The Every Student Succeeds Act definition describes professional development as part of a school or local educational agency strategy for giving educators the knowledge and skills students need. It says those activities should be sustained rather than stand-alone, intensive, collaborative, job-embedded, data-driven, and classroom-focused.

That statutory language offers a useful distinction:

• An event is something an educator attends.
• Professional learning is the process through which the educator develops and applies new capability.
• An effective professional-development system connects that learning to school priorities, working conditions, implementation support, and evidence of progress.

Not every useful learning experience must contain every feature at the same intensity. A short orientation can be appropriate when the goal is limited. But a school should not expect a single presentation to produce a complex, durable change in instructional practice.

Professional development and professional learning

The terms professional development and professional learning are often used interchangeably. Some education organizations prefer professional learning because it emphasizes an ongoing process rather than something delivered to educators during an isolated event.

The distinction is useful, but the label matters less than the design. Renaming a workshop does not make it sustained or job-embedded. When evaluating an opportunity, ask what participants will learn, how they will practice, what support follows, and how progress will be examined.

For this guide, professional development refers broadly to intentional work-related learning, while professional learning emphasizes the continuing process of applying and improving that learning.

Who participates in K–12 professional development?

Professional development is not limited to classroom teachers. Depending on the goal, participants may include:

• Teachers
• Principals and assistant principals
• Superintendents and district administrators
• Instructional coaches
• Curriculum and assessment leaders
• School counselors, psychologists, and social workers
• Special educators and specialized instructional support personnel
• Paraprofessionals
• Librarians and media specialists
• Early childhood educators
• Operations, technology, and student-services teams

The design should reflect the participants' roles. A principal learning to lead instructional feedback needs a different experience from a teacher learning to apply a new literacy routine. A district leadership team planning an implementation also needs different evidence and decision tools from the educators who will use the practice each day.

Common types of professional development

Professional development can use many formats. The right format depends on the outcome, participants, starting point, available time, and support required.

Workshops and institutes

Workshops introduce or develop knowledge and skills through explanation, demonstration, discussion, and practice. They are most useful when the objective is clear and participants have opportunities to work with realistic materials or situations.

A workshop may begin a longer learning sequence. By itself, it is less suited to changes that require repeated practice, feedback, and adaptation.

Instructional coaching

Coaching gives an educator individualized or small-group support as they work toward a goal. A coaching cycle may include goal setting, observation or evidence collection, feedback, modeling, practice, and reflection.

Coaching is often useful when educators need help transferring an idea into daily practice. Its value depends on trust, coach capability, protected time, role clarity, and alignment with school priorities.

Professional learning communities

Professional learning communities, grade-level teams, and subject-area teams allow educators to examine evidence, plan instruction, study student work, test approaches, and learn with colleagues.

Simply meeting on a schedule does not create a productive learning community. The team needs a defined purpose, useful evidence, skilled facilitation, and enough psychological safety to examine practice honestly.

Courses, certifications, and microcredentials

Courses and credentials can build deeper knowledge, document completion, or support role-specific requirements. Schools should distinguish between evidence that someone completed a learning sequence and evidence that the learning changed practice.

Conferences and webinars

Conferences and webinars can expose educators to new ideas, research, tools, and professional networks. They are especially useful for discovery and initial learning. Their impact is more likely to extend beyond the event when participants have a plan to evaluate, adapt, and apply what they learned.

Mentoring and induction

Mentoring and induction help educators or leaders enter a new role. Strong programs address immediate responsibilities, professional judgment, organizational context, relationships, and longer-term development rather than limiting support to procedural orientation.

Collaborative inquiry and lesson study

Educators may investigate a shared problem, study evidence, plan an approach, observe or analyze implementation, and refine the work together. These formats make learning part of the job rather than separate from it.

Independent and self-directed learning

Reading, online modules, podcasts, professional networks, and practitioner research can support development when they connect to a clear goal. Self-directed learning still benefits from reflection, application, feedback, or evidence that helps the learner judge whether the new approach is useful.

What does effective professional development include?

No format is automatically effective. Research and professional standards instead point toward design features that create stronger conditions for learning.

A 2017 Learning Policy Institute review examined 35 rigorous studies that found positive links among professional development, teaching practices, and student learning. The report identified seven features that appeared across many of the programs studied:

1. Content focus: Learning addresses specific curriculum, subject matter, pedagogy, or professional responsibilities.
2. Active learning: Participants analyze, design, practice, rehearse, observe, or apply rather than only listen.
3. Collaboration: Educators learn with colleagues and address shared problems of practice.
4. Models of effective practice: Participants see examples through demonstrations, materials, cases, video, observation, or other representations.
5. Coaching and expert support: Participants receive guidance while applying new knowledge or skills.
6. Feedback and reflection: Educators examine evidence, receive feedback, and refine their practice.
7. Sustained duration: Learning continues long enough to support understanding, practice, implementation, and improvement.

These features are not a guarantee. A program can include coaching or collaboration and still be poorly aligned, weakly facilitated, or inadequately supported. Context also matters. Schedules, leadership, curriculum, staffing, trust, and access to materials can determine whether educators are able to use what they learned.

Learning Forward's Standards for Professional Learning add a systems perspective. The standards address leadership, resources, evidence, implementation, equity, curriculum and instruction, and other conditions surrounding adult learning. This helps leaders move beyond asking, “Was the session engaging?” toward asking whether the organization created the conditions for learning to influence practice.

Examples of professional development in schools

The following examples show how an activity can connect to a larger learning process.

Introducing a new literacy curriculum

A district could combine initial study of the curriculum, demonstration lessons, collaborative unit planning, analysis of student work, implementation coaching, educator feedback, and adjustments based on evidence. The professional development includes the launch workshop and the full sequence supporting understanding and classroom use.

Developing first-year principals

A principal-development program could include mentoring from an experienced school leader, practice conducting observation and feedback conversations, case analysis, a peer cohort, role-specific goals, and reflection using school and staff evidence.

Building responsible AI practice

A school or district could combine approved-use guidance; examination of privacy, bias, accessibility, and academic integrity; subject- and grade-specific planning; opportunities to test tools using non-sensitive information; shared review criteria; and follow-up based on educator questions.

Improving support for students with disabilities

A learning sequence might bring general and special educators together to clarify an instructional or inclusion goal, study learner needs and legal responsibilities with qualified guidance, examine accessible materials and instructional models, plan collaboratively, practice, receive feedback, and monitor implementation and student access.

Specific legal or student decisions require the appropriate qualified personnel; professional development should not substitute for individualized services or legal advice.

Warning signs of weak professional development

Seat time, attendance, and the presence of a presenter provide limited evidence. Warning signs include:

• A topic selected without evidence of participant or student needs
• The same session assigned to roles with substantially different responsibilities
• No connection to curriculum, school priorities, or current work
• Passive presentation where application is required
• No time, materials, leadership support, or follow-up
• Success measured only through satisfaction surveys
• A provider promising guaranteed teacher or student outcomes
• A trend adopted without considering privacy, accessibility, evidence, or implementation

A positive participant survey can reveal whether a session felt relevant or well facilitated. It cannot by itself show that participants learned, used the learning, or improved outcomes.

How should schools evaluate professional development?

Evaluation should begin before selecting the activity. First define the problem and the expected chain of change.

1. Need: What evidence shows that professional learning is needed?
2. Participants: Which roles need to learn or do something differently?
3. Learning outcome: What knowledge, skill, judgment, or collaborative capacity should change?
4. Application: What should participants do differently in their work?
5. Conditions: What time, materials, leadership, coaching, or policy support will application require?
6. Evidence: What will show whether participation, learning, implementation, and relevant outcomes occurred?
7. Adjustment: When and how will the approach be revised?

The Institute of Education Sciences' Evaluating Professional Learning tool encourages schools and districts to create a logic model, write evaluation questions, use existing and new data, monitor implementation, and consider several levels of evidence. Those levels include participant reactions, participant learning, organizational support and change, use of new knowledge and skills, and student learning outcomes.

The levels should not be collapsed into a single claim. Attendance shows participation. A demonstration or assessment may show learning. Observation, artifacts, or work products may show application. Student evidence may help examine downstream results.

Even when these measures move together, leaders should be careful about attributing a complex student outcome to one professional-development activity without a design that supports that conclusion.

Questions to ask before choosing a professional-development provider

Fit

• What specific need will this engagement address?
• Which roles and experience levels is it designed for?
• How will the provider learn about our context?
• What assumptions does the approach make about time, staffing, curriculum, and leadership support?

Evidence and expertise

• What relevant experience does the facilitator have?
• What evidence supports the approach?
• Which claims come from independent research, and which come from provider data?
• Can the provider explain limitations and situations where the approach may not fit?

Learning design

• What will participants know or be able to do afterward?
• How will participants practice or apply the learning?
• What models, materials, and feedback are included?
• What support follows the initial session?

Implementation

• What must leaders do before, during, and after the engagement?
• How much participant time is required?
• What materials or technology are needed?
• How will the work align with existing initiatives?

Evaluation

• What evidence should be collected before the engagement?
• How will learning and implementation be examined?
• When will progress be reviewed?
• How will the provider respond if the approach is not working as intended?

A concise definition to use with your team

Professional development is intentional, work-related learning that builds educators' knowledge, skills, judgment, and collective capacity. Strong professional development connects to a defined need, includes opportunities for application and feedback, supports implementation, and uses evidence to guide improvement.

This definition is broad enough to include workshops, coaching, collaborative inquiry, mentoring, courses, conferences, and self-directed learning. It is specific enough to exclude the assumption that attendance alone equals development.

Frequently asked questions

Is professional development only for teachers?

No. Teachers are a major audience, but principals, district leaders, instructional coaches, paraprofessionals, specialized support personnel, early childhood educators, and other staff may all participate in role-specific professional development.

Does professional development have to be a course?

No. It can include coaching, mentoring, collaborative planning, professional learning communities, workshops, conferences, inquiry cycles, observation, or independent study. The format should match the intended outcome.

Is a one-day workshop professional development?

It can be one component of professional development. A short workshop can introduce information or a bounded skill. Complex changes usually require continued practice, feedback, support, and examination of implementation.

What is the difference between training and professional development?

Training often focuses on learning a defined procedure, system, or skill. Professional development can include training but may also build professional judgment, leadership, collaboration, and sustained improvement. In practice, the terms sometimes overlap.

How do schools know whether professional development worked?

They define expected learning and application before the activity, then collect evidence at appropriate levels. Satisfaction matters, but schools may also examine participant learning, organizational support, use in practice, and relevant downstream outcomes.
