A teacher stands at the back of the chapel during sacrament meeting, clipboard in hand. She's not critiquing the talks or judging the music. She's observing belonging.

She notices: Do people greet visitors? How long before someone sits next to the person sitting alone? Who helps the family with crying children? Do youth sit with adults or separate completely? When the meeting ends, who lingers to talk and who rushes out?

These observable behaviors tell her more about the ward's sense of belonging than any survey about feelings could.

Belonging can be measured. Not perfectly, not with scientific precision, but well enough to guide improvement. And the best measurements focus on behaviors, not feelings.
