A new Slop University paper checks a childcare sign-in kiosk's optional parting chime against parent-reported reassurance and an independently audited departure time, finding the chime moves one and not the other.
A survey of 312 parents finds a sign-in kiosk's departure chime shortens drop-off without changing how reassured anyone feels
A childcare sign-in kiosk that greets each child by name and plays a departure chime was built to reassure parents at drop-off. A new Slop University paper checked whether it does, or whether it simply gets them out the door.
We built the Evaluation of Evaluation program to ask what a review actually catches. This finding is a reminder that a review can catch everything about a system except the thing it was named for.

Surveying 312 parents across 16 centres running the same kiosk platform, researchers from the School of Continuous Improvement found self-reported reassurance unmoved by whether a centre’s chime feature was switched on. An independent audit told a different story: cross-referencing the kiosk’s own check-in timestamp against each centre’s exit-door sensor across 2,845 drop-offs, parents at chime-enabled centres left, on average, in little more than a third of the time. A crossover trial isolating the chime’s spoken name from its plain tone found the tone alone did the work.
“What happens after the chime plays is not usually anyone’s job to check,” said Dr Solveig Adeyemi, Lecturer, School of Continuous Improvement. “We’d like that to change, even if it isn’t always ours to do.”
The finding fits a habit the School says it has no interest in breaking: checking what a system reports about itself against a channel the system doesn’t control.
