New Zealand's 15-year-olds have fallen to new lows in the 2022 international PISA tests of reading, maths and science.
Almost 5,000 students were assessed from Aotearoa, with maths proving to be the weakest skill.

But Vaughan Couillault, President of the Secondary Principals Association, is more concerned by the figures around students' happiness, food security and safety.
Couillault spoke to Ingrid Hipkiss.
