Results were compared for students attending two categories of schools: those with up to 5 percent Pacific Island students (between 70 and 75 percent of the total sample of schools), and schools with more than 5 percent Pacific Island students (25 to 30 percent of the total sample). Because most of the Pacific Island students are concentrated into relatively few schools, it was difficult to create sensible subgroups for schools with higher or lower percentages of Pacific Island students.

The first data column in each table shows the percentage of tasks on which Pacific Island students in schools with more than 5 percent Pacific Island students performed statistically significantly lower than Pacific Island students in schools with less than 5 percent Pacific Island students. The second data column shows the percentage of tasks on which there were no statistically significant differences according to the proportion of Pacific Island students on the school roll. The final column shows the percentage of tasks on which Pacific Island students in schools with more than 5 percent Pacific Island students performed statistically significantly higher than those in schools with less than 5 percent Pacific Island students.
