People Are the CORE of Every Business

No matter what size business you work in, or at what level, understanding how your people work is core to making the work you do successful. The CORE Assessment® from The Lee Group helps organizations develop leaders and stronger teams through deeper understanding of self and others.


Framing the Opportunity

Developing leaders and strong teams begins with a deeper understanding of who they are and how they work.

The Lee Group has always taken a more engaged approach to helping organizations maximize the leadership and team potential of their people. Because leadership and team development isn’t about quick fixes – it’s about understanding what drives individuals, how they lead and where they are best positioned to succeed – The Lee Group is proud to offer The CORE Assessment®.

By leveraging The CORE Assessment®, we gain deeper insight through a unique, groundbreaking system of tools that helps businesses and individuals identify and develop leadership potential at every level.


A different kind of assessment. By design.

What It Measures

Unlike other tools and assessments, The CORE Assessment® measures a person’s innate unchanging nature, providing insight that helps align people with roles that suit both them and your organizational culture.

Rather than placing people into predefined boxes, the CORE reveals how individuals naturally think, approach conflict, learn, lead and interact, allowing development programs to be customized, relevant, and impactful.

Why It’s Different


This isn’t about changing people.

It’s about understanding them, helping them understand each other, and positioning them to succeed.


How The Lee Group Uses the CORE

Insight that turns into action.

The Lee Group uses the CORE insight to design leadership and talent development strategies tailored to your organization, from the production floor to the C-suite. By understanding the innate drivers behind behavior, conflict resolution, and learning style, we help organizations make smarter decisions about development, succession and role alignment.

What the CORE Allows You to Do

What organizations gain from The CORE Assessment®

For supervisors, managers, and directors, the CORE helps individuals understand their innate unchanging nature as well as that of everyone on their teams—improving how they interact with and lead others. Personal and professional relationships tend to improve and flourish when self-awareness and knowledge about others evolve.

The CORE provides a foundation for building essential leadership skills, including decision-making, conflict resolution, and relationship-building—giving emerging leaders the tools they need to grow with your organization. It can also identify those naturally wired to lead within your current team.

With deeper insight into what drives and motivates their teams, current leaders become more effective, more adaptable, and better equipped to lead diverse groups of people.

By developing and positioning leaders in roles that naturally suit and fulfill them, organizations see stronger engagement, better performance, and greater return on leadership investments.
