The Transforming Church Index (TCI) is an online tool that provides you with over 60 pages of data and information. It is designed to identify your church's organizational competencies and opportunities for improvement.

The TCI helps you assess how effective your church is at being a healthy organization — regardless of your size, denomination or context.
The 12 Scales expand into other areas such as: Member Satisfaction; Financial Health; Equipping the Members.

- Healthy Growth: What is our church's capacity to embrace change?
