School Data Dimension Notes

The dimensions are:

Year:

The calendar year in which students turned 18 - for example, the '2022' cohort are all students identified in ENROL who turned 18 in 2022 and were born in 2004. Information is not available for learners who were aged 18 prior to 2011.

Student Gender:

The gender of the students as recorded in ENROL.

Student Ethnicity:

The ethnic group the student belongs to, for example, Māori, Asian. The ethnic group data is presented at level 1 and total response. That is, leavers are counted for each level 1 ethnic group they have indicated they belong to. While a student may be represented in more than one ethnic group, they are only counted once in the ethnic group "Total".

Leaving Age:

The age (in years) on the last day of attendance at a New Zealand school before student's entry in tertiary study or the workplace. Note students who are enrolled beyond the end of the reporting year are included with those who left school when they were 18.

School Type:

The type of the school the student was attending at 18-years-old, or the last school the student attended before entry in tertiary study or the workplace, for example Composite (Year 1-15).

School Authority:

Decile:

The decile assigned to the school the student was attending at 18-years-old, or the last school the student attended before entry in tertiary study or the workplace.  Decile 1 schools draw the greatest proportion of their students from low socio-economic areas. Schools are assigned a socio-economic score based on five census derived socio-economic factors. The 10 percent of schools with the lowest scores are considered decile 1 schools; the next 10 percent of schools are considered decile 2 schools, etc.

This may not correspond to where the qualifications were gained or the location of the student in year of cohort.

Regional Council:

This may not correspond to where the qualifications were gained or the location of the student in year of cohort.

Territorial Authority:
