School leaver data is sourced from Ministry of Education data in the IDI. Foreign fee-paying students and exchange students have been excluded. Students are tagged as having completed a BCATS standard if they have ever completed one during their time at school. Those who do not achieve a standard are not included. The percentage of school leavers who completed a BCATS standard includes those who completed level 1 or level 2 standards.
