Appendix 1: Sample of schools

This evaluation involved 240 schools in which ERO carried out an education review in Term 4, 2011 and Term 1, 2012. The types of schools, roll size, school locality (urban or rural) and decile ranges of the schools are shown in Tables 1 to 4 below.

Table 1 shows that intermediate and composite schools were under‑represented, and contributing primary schools were over‑represented, in comparison to national figures. Full primary and restricted composite schools were representative of national figures. The differences were statistically significant.[c]

The national percentage of each school type is based on the total population of schools as at August 2012. For this study it includes full and contributing primary schools, intermediates, secondary, composite and restricted composite schools with students in Years 4‑8. This applies to roll size, locality and decile in Tables 2, 3 and 4.

The differences between observed and expected values in Tables 1-4 were tested using a Chi square test. The level of statistical significance was p<0.05.

Roll sizes for full and contributing primary schools, and intermediates are: very small (between 1-30); small (between 31-100); medium (101-300); large (301-500); and very large (500 ). Roll sizes for secondary, composite and restricted schools are: very small (1-100); small (101-400); medium (400-800); large (801-1500); very large (1501 ).

Based on location categories used by the Ministry of Education and Statistics New Zealand as follows: Main Urban population > 30,000; Secondary Urban 10,000 to 30,000; Minor Urban 1,000 to 9,999; Rural < 1,000.

A school’s decile indicates the extent to which a school draws its students from low socio-economic communities. Decile 1 schools are the 10 percent of schools with the highest proportion of students from low socio-economic communities, whereas decile 10 schools are the 10 percent of schools with the lowest proportion of these students.
