Transforming lives through the power of positive psychology

At the Langley Group Institute, we are doing more than teaching wellbeing – we are creating a movement of positive change, growth, and empowerment.

Who we are

The Langley Group Institute (LGI) is a leading education provider of positive psychology and wellbeing education, bridging the gap between the latest scientific research and practical,
real-world application.

As an Australian Registered Training Organisation (RTO #40655), we offer government-accredited courses that transform how individuals, organisations, and communities approach personal and professional growth.

What we do

Since 2013, we've been on a mission to help people create positive change in their lives and the lives of those around them.

Our flagship 11069NAT Diploma of Positive Psychology and Wellbeing, along with the recently introduced 11250NAT Certificate IV in Wellbeing Science, have empowered over 1,700 students with evidence-based tools from positive psychology, neuroscience, and emotional intelligence.

Founded by Sue Langley and Yulia Zlatkin, we continually evolve our curriculum to meet ASQA's high standards and make the science of human flourishing accessible and actionable.

The LGI approach

What sets us apart is our unique approach to learning. We transform complex concepts into practical, easy-to-apply strategies.

Guided by expert educators, students engage in immersive experiences that emphasise real-world applications.

Whether in-person or online, our learning environment fosters connection and growth, creating a ripple effect that positively impacts individuals, teams, and communities.
