If you plan to train adults, you cannot teach them the same way you would teach a Year 7 classroom. Malcolm Knowles’ adult learning principles explain why, and they form the foundation of every unit in TAE40122. This guide walks through all six principles of andragogy with plain examples you can use in your next facilitation session.
What are the adult learning principles?
The adult learning principles, known as andragogy, are a set of six assumptions about how adults learn best. They were developed by American educator Malcolm Knowles in the 1970s and 1980s. The six principles cover the learner’s need to know, self-concept, prior experience, readiness, orientation to learning, and motivation.
Andragogy contrasts with pedagogy, which describes how children learn. Knowles argued that adults bring different cognitive, emotional and practical needs to a learning environment. A training session built around andragogy respects adult learners as partners in their own learning rather than empty vessels to be filled. Every TAE40122 unit, from TAEDEL411 through to validation, traces back to these principles.
Who was Malcolm Knowles?
Malcolm Knowles was an American adult educator who published the foundational text “The Adult Learner: A Neglected Species” in 1973. Before Knowles, most adult training copied classroom techniques used on children. He proposed a separate theory that respected the experience, autonomy and practical motivation adults bring to learning.
Knowles drew on earlier work by Eduard Lindeman and popular education movements. His six principles were refined across multiple editions through the 1980s and 1990s. Today they sit at the heart of the Standards for RTOs 2025 approach to adult education in Australia, although current research has added nuance about individual and cultural differences.
Principle 1: Adults need to know why they are learning
Adults want a clear answer to “why does this matter to me?” before they invest attention and effort. Knowles called this the need to know. If an adult cannot see the connection between a topic and their work, life or goals, they disengage quickly. The trainer’s first job is always to make the relevance explicit.
Practical application: open every training session with the specific work problem it solves. Do not start with theory. Start with “by the end of this session, you will be able to issue compliant Statements of Attainment without triggering audit findings.” Then explain why audit findings cost RTOs their registration. The theory follows naturally once the relevance is established.
Principle 2: Adult self-concept is autonomous
Adults see themselves as independent, self-directing individuals responsible for their own choices. They resent being treated like children or told what to do without reasoning. Knowles argued that adult learners need to be partners in their own learning, not passive recipients of instruction.
Practical application: use language that invites rather than commands. Replace “you must now complete this worksheet” with “here is the worksheet we will work through, and I will check in after question five.” Give learners choices where possible: which scenario they analyse, which order they tackle tasks, which group they join. Small autonomy signals matter a lot in adult rooms.
Principle 3: Adults bring rich prior experience
Adults arrive in your training room with years of prior knowledge, experience and habits. This is an asset, not a deficit. Knowles argued that good adult training builds on prior experience through discussion, case studies, peer learning and analogy. It does not ignore or contradict it.
Practical application: open every topic by asking “what have you already seen that is similar?” Collect answers, use them as springboards, and only then introduce new content. In a TAE40122 delivery unit, this might mean starting a session on feedback by asking learners about the best and worst feedback they have ever received in their own careers. You have now primed them for the theory without a single slide.
Principle 4: Adults are ready to learn what they need
Adults become ready to learn when they face a situation that requires new skills or knowledge. Knowles described this as readiness tied to developmental tasks and social roles. A person who just took on a trainer role is ready to learn assessment design. The same person, six months earlier, would have found it dry and abstract.
Practical application: calibrate your examples, pace and depth to the specific situation your learners are in right now. A room of existing RTO trainers does not need the VET sector introduction that a room of career changers needs. A room of corporate L&D managers needs different compliance framing than a room of sole traders. Readiness is context-specific.
Principle 5: Adults are problem-centred, not subject-centred
Adults prefer to learn through real problems rather than abstract subjects. Where children accept “this is how long division works, you will use it later”, adults want “this is the problem you face and here is how to solve it.” Knowles argued that adult learning should be organised around life and work situations.
Practical application: structure training around case studies and problems, not topics. Instead of a session titled “Unit TAEDEL411”, run a session titled “What do you do when a learner says they do not understand your instructions?” The unit content is the same. The framing sells it. Problem-centring is especially powerful when learners have quite different industries, because the problems are often universal.
Principle 6: Adults are internally motivated
Adults are driven more by internal motivators like self-esteem, quality of life, job satisfaction and personal growth than by external motivators like grades or rewards. Knowles argued that the strongest adult learning happens when the learner has chosen to be there and sees the work as aligned with their own goals.
Practical application: connect every session’s outcomes to internal drivers. “By the end of today you will write assessment tools that you are proud to hand to your next learner and that ASQA cannot pick apart.” Internal motivators include respect from peers, mastery, impact on others, and personal identity as a professional. External motivators like “pass the course” work but produce compliance rather than genuine learning.
How do adult learning principles show up in TAE40122?
TAE40122 is built around andragogy. The facilitation units (TAEDEL411 and TAEDEL412) explicitly require trainers to demonstrate adult-learning approaches. The assessment units (TAEASS412, TAEASS413, TAEASS404) require learners to design and apply assessments respecting adult learner needs. The planning units (TAEDES411, TAEDES412) require you to apply adult learning theory in session design.
Your Learn TAE trainer will ask you to show andragogy in practice, not just describe it. Writing “I applied adult learning principles” is not evidence. Showing a lesson plan with a relevance hook, a prior-experience check-in, a problem-centred activity and an internally-motivating reflection is evidence. Every assessment tool we mark looks for this kind of applied evidence.
What are the limitations of Knowles' theory?
Knowles’ theory is useful but not complete. Research since the 1990s has shown that many of his assumptions also apply to younger learners in motivated contexts, and that cultural context affects adult learning strongly. Some learners prefer more structured direction early in their learning journey. Self-direction varies by individual, topic and confidence level.
Use andragogy as a strong default, not as a rigid rule. For a cohort of brand-new career changers entering an unfamiliar industry, more structure and guidance helps. For a cohort of experienced operators, more autonomy and problem-centring works better. The same trainer may use different blends on the same day for different groups. Current research on Kolb’s experiential learning cycle and Bloom’s taxonomy complements andragogy well.

Frequently Asked Questions
What is the difference between andragogy and pedagogy?
Pedagogy is the theory and practice of teaching children. Andragogy is the theory and practice of facilitating adult learning. The core difference is that andragogy assumes learners are autonomous, experienced and internally motivated, while pedagogy traditionally assumes more teacher direction.
Do adult learning principles apply to all adults?
Knowles’ principles apply to most adult learners most of the time, but not rigidly. Individual differences, cultural context and topic familiarity all affect how strongly each principle applies. Skilled trainers calibrate to the cohort in front of them rather than applying a fixed formula.
How do I apply adult learning principles in an online classroom?
The same principles apply online. Open each session with relevance, invite discussion from prior experience, give learners small choices in pace or activities, structure content around real problems, and connect outcomes to internal motivators. The medium does not change the principles, only the tactics.
Are adult learning principles required in VET assessment?
Yes, indirectly. The Standards for RTOs 2025 require that assessment reflect the learner’s context, and TAE40122 explicitly requires trainers to demonstrate adult-learning approaches. Assessment tools that ignore learner experience, autonomy or motivation will not meet the rules of evidence.
Who else has written on adult learning theory?
Other major contributors include Eduard Lindeman (who influenced Knowles), David Kolb (experiential learning), Jack Mezirow (transformative learning), Paulo Freire (critical pedagogy), and Stephen Brookfield (critical reflection). A TAE40122 trainer benefits from knowing at least the outline of each.
