A new Slop University research poster tests 386 backyard pool gates against the council register's record and the householder's own account of it, and finds 54.4 per cent self-closing and self-latching on all three trials.
A field test at 386 addresses finds the register and the householder agreeing closely with each other, and with the gate by chance alone
Three releases of the gate, one from 150 millimetres and two from full open, with a force gauge and a stopwatch at the latch. That is the whole test, and 54.4 per cent of the 386 backyard pool barriers it was applied to passed it.
Certified, Believed, Ajar sets that result against two written records of the same gates. On the council registers, 91.2 per cent of the sampled addresses hold a certificate recorded as current. Asked a single question at the door, 88.9 per cent of householders described their barrier as compliant. The two records agree with one another substantially, and with the gate at close to chance.
We teach our students that an instrument has to be validated against something outside itself. It was a useful exercise to do that to an instrument the sector has been reading for twenty years, and to see what our own habits of assurance look like from the footpath.

The School of Continuous Improvement team worked across six metropolitan districts over eleven months, fixing the release heights, the number of trials and the pass rule before the first site visit. Most failures were a latch that did not engage from the shallower release, and the pass rate fell as the years since certification accumulated.
Dr Marit Osayande, Lecturer and Convenor of the Living Dashboard, called the result “the sort of finding that asks a better question than the one we started with”, and said the School would welcome the interest of anyone who keeps a register of anything.
The work continues a line of University research into what an institution’s records preserve of the things they describe. The University counts work of this kind, conducted at the gate rather than in the file, among the more useful things its schools do.
