A state or state integrated school principal may consider the formal removal of a student through a stand-down from school for a period of up to 5 school days. A stand-down, for any student, can total no more than 5 school days in a term, or 10 days in a school year. Students return automatically to school following a stand-down.
The age-standardised stand-down rate is one where all subgroups, for all years, being compared are artificially given the same age distribution. In this indicator, the age distributions of students in each subgroup and year have been standardised to (or weighted by) the set of age-specific stand-down rates for all New Zealand.
As stand-downs are highest for ages 13 to 15, standardising for age will remove any differences due to one group having a younger or older population than other groups, or if the overall age distribution has changed from year to year. As such, the standardised rate is an artificial measure, but it does provide an estimate of how groups, or overall rates by year, might more fairly compare if they had the same age distribution.
