Why Leadership Development by Osmosis Takes Too Long (and What School Leaders Should Do Instead)
Do you feel leadership development in your school is slow? Have you stopped relying on leadership by osmosis yet? It’s time. To meet 2026 AITSL standards, school leaders must shift to Active Transport, a structured, intentional framework for leadership reflection and growth.
Most educators tend to switch to leadership roles simply by observing other leaders around them. Over time, they absorb behaviours, adopt communication styles, and embrace decision-making approaches almost unknowingly. In a nutshell, they learn by osmosis. Such learning happens in many schools. However, in today’s complex education environments, relying solely on passive learning may not be enough anymore.
The answer is intentional learning, reflection, and structured leadership coaching. That’s what effective leadership development requires. As an Australian leadership coachworking with educators for more than a decade, I’ve seen how powerful active learning can be in helping teachers and school leaders develop strong leadership capability.
Is Leadership Development by Osmosis Failing Most Australian Schools?
Relying on osmosis, i.e., the passive absorption of leadership traits by observing other leaders around you, is the slowest way to develop school leaders, which eventually results in the lack of structure. This leads to inconsistent school cultures and leadership burnout in today’s rapidly evolving education landscape. On the other hand, active transport, or intentional leadership development, is the only way to build the high-level competency required by AITSL standards.
What Is Osmosis Learning in Leadership?
As a Science teacher, I understand the term ‘osmosis’. It is an important concept taught not only as part of the science syllabus but also finds its way into Biology and Chemistry too. If science is not your thing, let me explain what it is in simple terms.
Osmosis is a chemical process that uses differences in concentrations across a semipermeable membrane to move liquid, or solvent, from the high concentration side to the low concentration side to even out the two sides. It’s the same process that makes your fingers go wrinkly when you have been in water for too long; the liquid in the skin cells of your fingers loses fluid to the surrounding water.
Why Leadership Development by Osmosis Is Slow
Leadership development by osmosis takes too long and is often inaccurate. When educators learn leadership simply by observing others, they may absorb both strong leadership practices and ineffective habits without recognising the difference.
This is not a science article, but I can’t help but apply the concept of osmosis to leadership development. Many people learn about leadership from reading about it. Some are fortunate to do some formal study. Most learn how to lead, whether that leadership is good or bad, by observing others and working alongside or under other leaders. In other words, by osmosis.
Osmosis, defined in terms of leadership development, is the gradual process of unconscious assimilation of ideas and knowledge. It just seeps in, both the good and the bad examples of leadership, and they somehow become part of what we understand our leadership to be. We all have an idea of what we think is good leadership, but if we don’t have great role models around us, how would we really know?
The Problem with Passive Leadership Learning
- Unclear leadership expectations
- Inconsistent leadership behaviours
- Delayed development of leadership confidence
- Repeating ineffective leadership habits
If they are a good leader, we can learn a great deal about what makes strong leadership. If they are a poor leader, we still learn a lot about leadership, but this time in terms of what not to do, and that is only if we can recognise it as what we shouldn’t be doing. Leadership development by osmosis takes too long and is so often inaccurate.
In my career in school leadership, sadly, I came across only a few good leaders. It is therefore not surprising to me that I have dedicated my business to helping leaders in schools be the leaders we need them to be, role models for their communities, so that students, staff and parents can experience quality leadership and from there, craft better working relationships in collaborative communities.
A Better Approach: Active Leadership Learning
Let me introduce you to another science concept, that of ‘active transport’. This is the process whereby it supports the transport of the solute, or the particles floating in the liquid, to move across a semipermeable membrane. Instead of relying on passive learning, leadership development can become far more effective when we take a more active approach to learning from other leaders.
I began Coaching Focus in 2015, after leaving the role of Deputy Principal in one of Melbourne’s leading independent girls’ schools. I now work with staff in schools right across Australia and New Zealand, providing quality leadership development.
In our programs, everyone gets a Coaching Focus bent pen and a notebook for a specific purpose. It’s not to take notes throughout the program; they get a full workbook for that. Instead, they are to use the concept of active transport to learn from others about leadership. I encourage them to identify specific leaders to watch and learn from, and to do it actively, and I share with them a specific framework to pull apart what they see.
I encourage them to write down what they observed and learned in each example, incident or meeting; wherever the examples of leadership show up, both the good and the bad. Then I ask them to put themselves in that leader’s shoes and rewrite part of the story in terms of how they would have managed the situation.
The framework we use is the STAR Technique. This is the same framework used in behavioural interviewing, when you retell a story succinctly to the interview panel. It’s a great method to use to get your story told in about 2 to 3 minutes before the interview panel becomes bored and you see their eyes glaze over.
The transition from passive observation to active mastery is the actual foundation of our leadership programs. I don’t just give you a notebook; I introduce you to the Coaching Focus Leadership System – a proprietary framework that thousands of Australian educators use to turn daily school interactions into high-level leadership data!

How Educators Can Actively Develop Leadership Skills
One simple way educators can actively develop leadership capability is by analysing leadership situations using a structured framework. In our leadership coaching programs, I often introduce educators to the STAR framework, which is commonly used in behavioural interviews, but works just as well for leadership reflection.
While many are just familiar with the STAR Technique for interviews, our programs teach you how to use it as a Diagnostic Leadership Tool.
- The STAR-R Method: We go beyond the “Result” to “Reflection” and “Recalibration.”
- The Application: In our Elevating Leadership Program, we spend entire modules live-coding these reflections to ensure you aren’t just “watching” leaders, but actively architecting your own leadership identity.
Why Active Leadership Development Matters More than Ever Today
Education leadership challenges have evolved over the years. Today’s school leaders face far more complexity than even a decade ago.
Educators are navigating
- Rapid changes in education systems
- Increasing well-being challenges among students and staff
- Complex communication with parents and communities
- Growing expectations for strategic leadership in schools
Because of this, leadership capability cannot be left to chance. Structured leadership coaching and professional development for educators help school leaders develop the confidence, clarity, and communication skills needed to lead effectively.
Observing and analysing the actions of other leaders helps you to define the type of leader you want to be. My leadership development programs focus on developing leaders who are clear, confident, consistent and considered and being self-reflective is vital to developing these traits.
So your next step is to get yourself a pen and a notebook so you are ready for the start of the school year, ready to begin observing leaders around you and crafting your own style of leadership or come to one of my programs and I will give them to you.

For Aspiring Women Leaders
In 2016, we launched The Leading Edge: Women in Education Conference, a two-day event designed for aspiring women leaders in independent schools. The conference is intentionally designed for a smaller group setting, allowing deeper personal exploration, leadership reflection, and meaningful conversations.
Since its launch, the conference has been held five times and continues to receive outstanding feedback from participants.
Across the two days, delegates gain practical insights and clear actions to help them grow as leaders and become the role models our schools need. As a former school leader, leadership coach, and behavioural analyst, I designed the conference to address the real barriers women face in leadership and help them move their careers forward with purpose and direction – no more osmosis learning.
Key Features of the Conference
- DISC Psychometric Profile
Each delegate receives a personalised DISC assessment and a detailed 40-page report highlighting strengths, challenges, time wasters, and opportunities for leadership growth. - Private Accelerator Coaching Session
Following the conference, delegates participate in an individual coaching session to unpack their DISC results and develop a practical leadership and career action plan. - Leadership Conversations with Female Principals and Senior Leaders
Hear directly from experienced female school leaders through panel discussions and small group conversations, with opportunities to ask questions and gain real-world leadership insights. - Focused Leadership Development
