A School of Continuous Improvement paper binds partner-route residual funding to leftover headcount at the school-gate stop.
HELD treats children left at the kerb when licensed load is called as the residual the route is paid for
The driver calls fifty-seven and closes the doors. The children still on the kerb are, in a paper released today, the residual the route is paid for.
Dr Torun Ezeigwe, Senior Lecturer and Director of the Master of Applied Measurement, with Associate Professor Casimir Beng, Lead of the Adaptive Metrics Lab, and Dr Joost Nwosu, Postdoctoral Fellow, treat the licensed-load integer as a sharp cutoff across 2,660 afternoon departures on 38 contracted school-bus routes. Boarders just above the cutoff, scored on the service they eventually ride, settle more completely than boarders just below it. Held-over Eligibility at Licensed Departure, HELD, converts that leftover headcount into a published funding share.
The School of Continuous Improvement has made the leftover queue a standing claim on the residual pool.
A child who waits is already a complete boarding. The register only has to count them.

Enumerators at the school-gate stop recorded boarding order against the licensed-load call and scored the service each child eventually rode. Completeness at the cutoff is discontinuously higher on the held-over side. On six pilot routes the School has adopted HELD as the standing eligibility rule for residual funding, lowering licensed load by one passenger at each six-week review with no ordinary override. Leftover headcount on those routes rose with the formula that pays for it.
