Stop Counting Heads, Start Measuring Health: One Honest Look That Changes Everything

Here is a question that haunts a lot of us who pastor small churches: if numbers are not the only way to know whether our church is healthy, what else is there? Many faithful pastors honestly do not know the answer. We have spent so long crunching attendance figures that we have lost the language for what a healthy church actually looks like.

Let me give you some good news right at the start. Numbers may inform us, but they don't define us. Your church can be measured for health without being reduced to a headcount. In fact, the whole field of church health rests on one stubborn claim: quality is the foundation for quantity. Quantity follows quality, not the other way around. So if you are under 100 and feeling stuck, the most freeing thing you can do is stop asking "how do we get more people?" and start asking "where are we least healthy, and how do we fix that first?"

The one reframe that changes how you lead

A church under 100 cannot work on everything at once. You do not have the staff, the bandwidth, or the volunteers for it. This is exactly where a good health assessment earns its keep: it tells you the single highest-leverage thing to fix next instead of leaving you to guess.

The master logic here comes from Natural Church Development (NCD), the most researched instrument in the field. NCD measures eight quality characteristics (things like empowering leadership, passionate spirituality, inspiring worship, holistic small groups, and loving relationships). The active ingredient is the adjective, not the noun. It is not enough to have leadership; you need empowering leadership.

But the genius is what NCD calls the "minimum factor." You find your lowest characteristic and improve that one first, because it is dragging your overall health down the most. You raise it, re-survey, find the new lowest area, and repeat. Nearly every solid health tool borrows this "lowest area first" rule. Once you grasp it, you stop scattering your energy across ten fronts and pour it into the one that matters most this season.

Scored tools versus definitional tools

Before you pick an instrument, know that they come in two flavors.

Scored diagnostic tools give you a number per area so you can act on the lowest one. A few worth knowing:

Karl Vaters' Healthy Church survey was built explicitly for small churches. It is free, fast, and rates 16 principles across four categories (Theology, Leadership, Mission, Attitude) on a 0 to 5 scale. The bands are blunt and useful: above 70 is spectacular, the 50s and 60s are good, the 30s and 40s signal real trouble, and below 40 is what he calls the "Big Rut."

Multiplication Network's "Take Your Church's Pulse" scores 10 characteristics from 1 to 10 with a clean decision rule: above 7 is a strength, 7 or below is a growth area. Run it before and after you make changes to compare.

The Healthy-Tree tool keeps it simple with six characteristics on a 1 to 5 scale, then asks you to name one strengthening action for the low scores.

The CRCNA Healthy Church Executive Survey covers 11 areas and is designed to be retaken annually so you can watch trends over time.

Definitional tools describe health without scoring it. The well-known 9Marks framework names nine marks of a healthy church (expositional preaching, gospel doctrine, evangelism, membership, discipleship, and more) but deliberately offers no scale. It is a rubric, not a thermometer. If you use one of these, pair it with a scored tool so you can still find your minimum factor.

Count what actually matters

If you want to keep numbers without being enslaved to attendance, borrow GCI's "markers of maturity" idea. Instead of tracking only how many people showed up, track things like the percentage of new members who were previously unchurched or dechurched, or the number of members actively using their gifts in ministry inside and outside the church. These are still numbers, but they measure transformation rather than crowd size. For a small church, this might be the single best move you make.

The dimensions that keep showing up

Here is the quietly reassuring part. Strip the labels off all these different instruments and the same handful of dimensions keep reappearing: leadership, worship, prayer and spirituality, relationships, evangelism, structures, and discipleship. That convergence is exactly why these tools feel trustworthy, and it is the foundation behind the 100 Strong Health Check. Different builders, same load-bearing walls.

Turn the diagnosis into one plan

A score is not the goal. Action is. Once you have your numbers, resist the urge to fix everything. Identify your lowest one or two areas, choose a single strengthening action for the lowest, and work it until your next survey. Then find the new minimum factor and repeat. That rhythm, repeated patiently, is how a 40-person church becomes a 75-person church and beyond.

If you want help connecting these health areas to your growth milestones, the 100 Strong /assessment and /milestones tools are built to walk you through exactly this.

Your challenge this week

Pick one free, scored instrument (Karl Vaters' 16-principle survey is a great fit for a small church) and complete it yourself this week. Circle your single lowest score, and write down one concrete action you can take in the next 30 days to strengthen just that area. That is your minimum factor. Start there.
