# Mastery

Mastery is [Success.co](https://www.success.co/)'s built-in EOS learning platform that helps team members learn and master EOS concepts directly within [Success.co](https://www.success.co/).

With Mastery, users can complete structured EOS courses, track their progress, receive lesson recommendations, and celebrate course completion. Managers and Implementers can also monitor team progress and identify opportunities for additional coaching.

## The Five Foundational Tools

The 5 Foundational Tools course is designed for every person in your organization who is running on EOS. It introduces the core EOS concepts and tools that help teams gain clarity, improve accountability, and work more effectively together.

We recommend that all team members complete this course before moving on to more advanced EOS topics.
