Malcolm Knowles' six adult learning principles (andragogy) say adults learn best when they: 1) know why they need to learn something; 2) are treated as self-directing; 3) can use their experience; 4) are ready because the learning helps with a real task; 5) work on problems rather than subjects; and 6) are driven by internal motivation. Design training around relevance, participation and practice.
What is andragogy?
Andragogy is the art and science of helping adults learn. The term was first used by German educator Alexander Kapp in 1833, but it was American adult educator Malcolm Knowles who developed it into a working theory from the late 1960s, most fully in his book The Adult Learner.
Knowles contrasted andragogy with pedagogy, the traditional teacher-directed model in which the teacher decides what is learned, when and how. He argued that as people mature, they become more self-directing, accumulate experience, and learn best when learning solves problems they actually face. Knowles initially set out four assumptions and later added two more, giving the six adult learning principles most trainers use today.
For corporate trainers these principles are practical, not academic. They explain why a two-hour lecture on a compliance policy fails, and why the same content works as a 45-minute case discussion built on situations participants have seen. You will find a short definition in our training glossary.
Knowles' 6 adult learning principles at a glance
The six principles describe what adults bring to learning and what they expect from it. This table summarises each with a workplace example and the design move it implies.
| Principle | What it means | Workplace example | Design move |
|---|---|---|---|
| 1. Need to know | Adults want to know why they should learn something before investing effort | Sales staff told to attend CRM training engage only once they see it shortens their reporting time | Open with the business problem and "what's in it for you" |
| 2. Self-concept | Adults see themselves as responsible for their own decisions and resist being directed like students | Experienced engineers bristle at a trainer who reads slides aloud and forbids questions | Offer choices, invite goal-setting, treat participants as peers |
| 3. Experience | Adults bring a large, varied stock of experience that is both a resource and a source of habits | A team of branch managers has handled hundreds of customer complaints between them | Use discussion, peer teaching and case material drawn from their work |
| 4. Readiness to learn | Adults become ready to learn what they need to cope with real-life tasks and roles | A newly promoted team lead is suddenly keen on feedback skills | Time training close to role changes and real needs |
| 5. Orientation to learning | Adults are life-centred, task-centred or problem-centred rather than subject-centred | Finance staff learn a new tax rule faster through three real invoices than through the full circular | Organise content around problems and tasks, not chapters |
| 6. Motivation | The strongest motivators are internal: job satisfaction, self-esteem, quality of life | A trainer who links a skill to career growth gets more effort than one who cites a mandate | Connect learning to competence, growth and recognition |
The six principles explained with workplace examples
Each principle translates into specific choices about how you open, run and close a session.
1. Need to know: explain the why first
Adults need to understand why they are learning something before they commit to it. In practice, many corporate participants arrive "nominated" rather than by choice, so the trainer's first job is to make the case. Open with a real problem the topic solves, a quick self-assessment that reveals a gap, or a short story of what goes wrong without the skill. A quality-control module that starts with last quarter's actual rejection reasons gets attention a definition slide never will.
2. Self-concept: treat learners as self-directing
Adults see themselves as responsible for their own lives and resent being treated like schoolchildren. Ask participants what they want from the session, let them choose between case options, and use agreements rather than rules. In hierarchical workplaces, this also means making it safe for a junior participant to disagree with a senior one in the room.
3. Experience: use what is already in the room
Adults bring experience that is the richest resource in any session. A group of 15 supervisors may have more collective experience of shop-floor conflict than any case study. Use it through pair discussions, "share a time when", peer coaching and problem clinics. Knowles also noted the downside: experience brings habits and assumptions, so good design helps people examine old approaches, not just confirm them.
4. Readiness to learn: time it to real need
Adults become ready to learn when they face a task or role that demands it. A new manager is far more receptive to delegation skills in the first month of promotion than a year before. Schedule training close to role changes, system launches or new responsibilities, and use pre-work and post-session reinforcement so learning meets the moment of need.
5. Orientation to learning: build around problems
Adults are problem-centred, not subject-centred. Rather than "Module 3: Principles of Negotiation", frame it as "How to hold your price when a key client asks for a discount". Organise content around tasks people perform, and let them practise on their own real cases. Writing objectives with action verbs from Bloom's Taxonomy keeps the focus on what participants will be able to do.
6. Motivation: tap internal drivers
Adults respond to external motivators such as promotions or mandates, but Knowles argued that the most powerful drivers are internal: the desire for competence, self-esteem, recognition and a better working life. Show participants their own progress, for example by recording a short practice at the start and end of a session, and connect skills to the career they want.
Worked example: redesigning a policy session with andragogy
This illustrative example shows the principles applied to a common corporate session.
Scenario: An HR team at a Chennai-based services company runs a 90-minute session on the new leave and attendance policy for 30 team leads. The current version is 40 slides read aloud, followed by questions. Feedback says it is "boring" and leads still apply the policy inconsistently.
- Need to know: open with three real (anonymised) disputes from last quarter that arose from inconsistent application.
- Self-concept and experience: tables list the leave situations they find hardest, which become the agenda.
- Orientation: each table solves four realistic cases using a one-page policy summary instead of the slides.
- Readiness: the session is moved to the week before the policy goes live, and a short reference card follows by email.
- Motivation: the close focuses on how consistent decisions reduce escalations and protect the lead's credibility with the team.
The content is the same; the experience is completely different. The cases are debriefed using the What–So What–Now What model so each lead leaves with a clear rule of thumb.
Adult learning principles checklist for your next session
- The first five minutes explain why this topic matters to participants' work
- Participants have a say in goals, cases or the order of topics
- At least one activity draws directly on participants' own experience
- Training is timed close to when participants need to use the skill
- Content is organised around real problems or tasks, not textbook chapters
- Lecture blocks are short, and practice takes more time than input
- The close connects the skill to participants' growth and confidence
Common mistakes when applying andragogy
- Treating it as "no structure". Self-direction does not mean an agenda-free session. Adults still need clear objectives, good materials and a skilled facilitator.
- Assuming all adults are equally self-directing. New joiners or people facing an unfamiliar topic may need more guidance at first. Knowles himself presented andragogy and pedagogy as a continuum.
- Using experience without challenging it. Inviting stories is not enough; help participants test old habits against the new approach.
- Explaining "why" with policy instead of benefit. "It's mandatory" answers the need to know but kills motivation.
- Ignoring the room's reality. In mixed-hierarchy Indian workplaces, participation needs psychological safety; use pairs and tables before full-group discussion.
Where adult learning principles fit in the Bodhih Certified TTT
Adult learning principles are the starting point of the Bodhih Certified Train The Trainer (TTT) Program. Day 1 (Foundations of Training Excellence) covers Knowles' andragogy alongside Kolb's Experiential Learning Cycle and Bloom's Taxonomy, followed by a recorded baseline delivery. Over the following days you apply these principles to your own training content, so by Day 4 you leave with a redesigned module. The program runs about 80% practice, which is itself andragogy at work. Dates are on the fees and batches page. For trainers who want to go deeper into design, Bodhih also offers a learning experience design course.
Frequently asked questions
What are Knowles' 6 adult learning principles?
Malcolm Knowles' six assumptions of andragogy are: adults need to know why they are learning something; they have a self-concept of being responsible for their own decisions; they bring rich experience; their readiness to learn rises when learning helps with real-life tasks; their orientation is problem-centred; and their strongest motivation is internal, such as job satisfaction and self-esteem.
What is the difference between andragogy and pedagogy?
Pedagogy traditionally describes teacher-directed learning, where the teacher decides what, when and how learners study. Andragogy, popularised by Malcolm Knowles, describes how adults learn: they want relevance, draw on experience and expect a say in their learning. Knowles later presented the two as ends of a continuum, so the right approach depends on the learner and situation, not only age.
Who developed andragogy?
The word andragogy was first used by German educator Alexander Kapp in 1833, but American adult educator Malcolm Knowles developed it into a theory of adult learning from the late 1960s. His books, including The Modern Practice of Adult Education and The Adult Learner, set out the assumptions that corporate trainers still use to design workplace learning today.
How do you apply adult learning principles in corporate training?
Start every session by explaining why the topic matters for participants' work, involve them in setting goals, use their experience through discussion and case material, build activities around real problems they face, and schedule learning close to when they need it. Keep lecture short and practice long, and connect outcomes to things participants care about, such as competence and growth.
Is andragogy still relevant today?
Yes, although researchers have debated whether its assumptions apply only to adults. Most practitioners treat Knowles' principles as practical design guidelines rather than strict laws. They fit well with experiential learning, microlearning and on-the-job support, and they remain a core part of most train the trainer curricula because they explain why participation-heavy training works better for working professionals.
Which principle of adult learning is most important?
There is no single most important principle; they work together. In practice, many trainers find that the need to know and problem-centred orientation make the biggest immediate difference, because adults who cannot see why a topic matters to their work disengage early. Getting relevance right in the first ten minutes makes the other principles much easier to apply.
