an introductory guide to maturity and identity maturation
Maturity goes beyond age - it's about how we grow in self-awareness, perspective, emotional resilience, and along multiple strands of development. Aephoria’s maturity assessment tool, based on an adult development model rooted in years of research and experience, guides coaches and their clients through these development stages.
what is maturity?
Maturity is a journey, not a destination. We can grow and mature throughout our life. It's about truly knowing ourselves, seeing and valuing different sources of data and meeting the existential challenges we face.
Maturity and age are not completely correlated; we have all seen very mature young people and very immature old people. Nor is maturity simply emotional intelligence (EQ); it’s broader, comprising multiple lines of development, including spiritual, somatic, cognitive, emotional, moral and other areas. We do not develop equally along all these lines of development, but rather excel in a few areas, which pulls us up into a different way of being.
In the past, maturity was often equated with fitting in with other so-called “normal” adults. However, later research suggested that maturity at later stages might actually set us apart from others, as we grow in idiosyncratic ways that don't always align with the norm.
what is the adult development model?
At Aephoria, our adult development model combines Constructive Development Theory, integral philosophy, and existential philosophy to offer a comprehensive view of human growth.
Informed by Susanne Cook-Greuter's work, our development model views maturity as a series of evolving stages, with none 'better' or 'worse' than the other. Each stage adds value in its own right and is essential to our evolution. There is no stage to universally aspire to, and each person's maturity journey is unique. However, some stages are more useful in some contexts and roles than others.
The inclusion of existential philosophy in our model allows us to notice how people at each stage have unique existential challenges that must be met for them to grow. The work of liberation theorist and existentialist Steve Biko brings in the idea that the more varied our identities inside, the more we can connect to varied identities and situations outside.
This means we can hold more perspectives and handle differences, diversity, and inclusion more easily. It means we have more powerful ways of understanding the world and an increase in agency as we discover how to shift our outside worlds.
“The adult development model is built on the idea that as we mature and grow, we take more identities into ourselves. The more identities we have, the more agility we have in the world. ” - Dr. Julia Kukard.
“At earlier maturity levels, people strive to fit in and be successful in a conventional or socially acceptable way. At later stages, people want to express their inner worlds more fully and worry less about what people think of them.”
- Dr. Julia Kukard
what are the different stages of maturity?
At Aephoria, we work with eight stages of maturity, divided into two groups: conventional and post-conventional. At conventional stages, we are largely dictated by our external circumstances and conventional norms around success in life. At post-conventional stages, our meaning-making becomes idiosyncratic, and our thinking is multi-perspectival and broad.
All stages are useful and valuable. People at earlier stages bring the strengths of building community and social cohesion, compliance, and upholding social norms. People at later stages are useful in leading change, building inclusion, creating strategy, and radical innovation. They tend to be more comfortable with uncertainty, complexity, paradox, and change and are particularly good at leading when these conditions are the norm.
Systems are stronger when there is diversity, including diversity of maturity levels. We need the contributions of all maturity levels to enable us to thrive in good times and in difficult ones.



Based on our decades of experience in emerging countries, we’ve noticed higher percentages at early stages of maturity, lower in the middle, and similar at the later stages compared to developed nations.

why work with maturity?
Working developmentally with maturity supports people's effectiveness in their current stage and helps them grow forward. This developmental work is more important than personality work, especially at later stages where personality fixations change (i.e., habits and fixations become less sticky).
Aside from supporting people’s growth, this work can create windows in the thinking of later stages and use these insights to build more effective strategies, innovations, and coping strategies for our volatile, uncertain, complex, and ambiguous world.
how to work with maturity
First, we need to understand the person. Second, we need to understand the context in which they operate. Thirdly, we need to understand the issue they want to work on. Last but not least, we need to understand the developmental direction they want to take.
There are some specific ways of having a conversation that supports this shift. By combining all these elements, the idea is to create new information and make an offering to that person so they can choose what to do with more information, identify what is meaningful to them, and create a direction and flow for their life.

Broaden the information they have available. Ask questions such as "How is this?" or "What was your experience of that?" Dr. Julia Kukard recommends asking, "What are you envious of?" because envy can show us where someone wants to go.

Deepen their understanding of how the context affects the situation. This can be generated by asking questions about the context in particular what changes are occurring and how they are affecting the person and others. A useful question is “what behaviour is the context suggesting to you? Will you go along or not?”.

Explore their underlying narrative. What’s the story the client’s telling themself? Maybe it’s “I’ll never get a degree,” or “People don’t like me, and they never will.”

Introduce relevant theory if it feels right, and you can find the right words. This theory could be a developmental typology, such as the step theory of different levels of adult development or existential ideas about life.

about the aephoria maturity assessment
We all know that humans grow and mature over time, and our behaviours and perspectives change with each phase of life. Aephoria’s adult development model offers a way to understand this journey.
While it's true that maturity doesn't always follow a clear, step-by-step process, as the adult development model might suggest, this framework is a practical and insightful guide. Our work with thousands of people has shown that it provides an effective and useful map of the process of human development.
Our Aephoria Combined Assessment combines the Enneagram personality assessment with a measurement of Maturity stages to provide a comprehensive and accurate picture of a person's development journey. As a result, we can devise developmental pathways that are meaningful to people and add value to the organisations in which they work.
Our experience over more than a decade suggests that people at earlier stages prefer working with the Enneagram and people at later stages with the Maturity model. Our reports cater to these two groups using different languages and formats that speak to their separate mindsets.
what is sentence completion in an assessment?
Sentence completion in an assessment is a tool for gaining insight into a person's thoughts, feelings, and attitudes. By providing the start of a sentence and asking the individual to finish it, this method reveals underlying beliefs, motivations, and emotional states in a natural and unguarded way.
Aephoria’s maturity assessment tool utilises 15 open-ended sentence stems to support deeper expression. Responses are evaluated by one human expert alongside cutting-edge machine learning to ensure accuracy. Coaches accredited in Aephoria Maturity can use the maturity assessment within their coaching practice. Our validity and reliability document is available on request.

frequently asked questions about the aephoria enneagram
Adult development includes growing self-awareness, improving one's capacity to deal with complexity, developing emotional intelligence, and enhancing one's ability to see situations from multiple perspectives. It's about evolving how one handles relationships, manages one's responses, and aligns one's life with deeper values.
A maturity assessment evaluates where you are on your growth journey. It helps you understand your strengths, challenges, and areas for further development, offering a clear pathway to becoming more effective and fulfilled. It provides a map showing you the road ahead on your growth journey.
As you progress from earlier stages of maturity to later stages, your leadership abilities evolve. You become better at understanding others, making strategic decisions, and handling complex situations with empathy and insight. You become more inclusive in your thinking, which enables you to innovate more effectively. This supports agility and our ability to meet the challenges we face and to see the world as it is rather than how we are in it.
Our maturity assessment is paired with the Enneagram personality test to identify your core motivations and personality traits and map out your stage of adult development. It offers deeper insights into how you navigate life's challenges and how you can continue to grow, through the lens of your personality (and vice-versa).
The maturity part of the questionnaire shows where you are in the journey of working with and through your personality. It does not hone in on particular traits like introversion or extroversion. However, it can offer you rich existential insights into your life.
Understanding where you are in your maturation journey helps you identify what might be next and how to get there. It shows you where you might be stuck and how to become fluid again. It empowers you to make informed decisions about your growth and how you can contribute more effectively to your relationships, work, and community.
With a more vibrant and varied inner world and more agency, we can then co-create a fluid relationship with the world. This is where we are in sync with the world; it affects us, and we affect the world.
We can be ourselves, connect to the world, and direct our lives meaningfully and purposefully. We are not stuck in outdated, irrelevant and ineffective uses of our energy, and we can find ways to add our unique value to the world . This is possible in earlier stages of maturity, but our capacity for being fluid is greatly enhanced at later stages.
