Strength Development Index

The Strength Development Index, a Church Health Survey, is a 160-item questionnaire that measures a church’s perceived health in six purposes of the church:

• Worship
• Evangelism
• Fellowship
• Discipleship
• Prayer
• Ministry

Church leaders choose a sampling of the church membership to complete the 30-40 minute survey. Using the survey information, a 40 page report is provided sharing a Church Health evaluation for the church.
