School of Emergent Priorities researchers fitted a rotation model to four years of primary-school newsletter award columns and report that the weekly merit certificate follows an unwritten roster faithful enough to name most recipients a median of nine weeks in advance.
A rotation model fitted to four years of newsletter award columns recovers each classroom's unwritten roster and the end-of-year clearance of unrecognised names
The certificate is handed over at Friday assembly. The decision, new research suggests, was largely settled two months earlier.
Recovering the Unwritten Roster, a research poster released today by the School of Emergent Priorities, fits a hidden-rotation model to 9,806 Student-of-the-Week lines drawn from four years of newsletter archives across 118 primary classrooms. In 71 per cent of them, a fixed rotation with occasional recorded swaps reproduces the complete award sequence, and the recipient can be named a median of nine weeks before the certificate is presented. The rotation pauses for cancelled assemblies, photo weeks and grandparents’ day, then resumes without skipping a name; in the final fortnight of the year, certificate density roughly doubles as classrooms clear every unrecognised name before the holidays.
The remarkable thing is not that teachers plan recognition; it is how faithfully the plan survives everything a school year throws at it.

Working entirely from public archives, the team harmonised award columns, assembly notices and calendar pages into a single sequence record, with given names replaced by roster positions at ingest and the analysis plan lodged before the final year of columns was read. Dr Petra Umbile, Postdoctoral Fellow, called the corpus “a rare case of an indicator that reaches every member of its population exactly once, on schedule”.
The finding sits comfortably within the University’s conviction that schedules deserve the same scholarly attention as the achievements they administer. The full poster is available from the University’s research repository under an open licence, doi:10.5555/slop.e9bpba.
