Growth Driver
High-attendance Sundays (Easter, Mother's Day, Back-to-School, Christmas) used as retention benchmarks.
A growth driver is a predictable, calendar-driven Sunday that consistently produces above-average attendance. Kingdom Metrics recognizes several standard growth drivers: Easter, Christmas/Christmas Eve, Mother's Day, Back-to-School Sunday, and other culturally significant dates that vary by region.
Growth drivers differ from material spikes in that they are expected rather than surprising. The analytical value of growth drivers is not in the spike itself — everyone knows Easter will be big — but in what happens afterward. Kingdom Metrics tracks post-driver attendance to calculate Growth Driver Retention (GDR), which measures how effectively your church converts one-time visitors into regular attenders.
Why it matters for your church: Growth drivers are your biggest guest-attraction opportunities of the year. Tracking them systematically lets you compare year-over-year performance ("Did Easter bring more people this year?") and evaluate your follow-up effectiveness ("Did we retain more of them this time?").
