ERO investigated curriculum principles and teaching as inquiry in 109 schools (67 primary and 42 secondary) reviewed in Term 2 and 3, 2010. The number of classrooms evaluated in each school was dependent on the school size as shown below.

Tables below show the demographics of the sample. The sample has been compared to the national percentage[23] and comments made, where relevant, about any statistical differences between the observed (sample percentage) and expected (national percentage) values. The differences between observed and expected values were tested using a Chi square test. The level of statistical significance for all statistical tests in this report was p<0.05.

Table 10 shows that the sample was not representative of national figures in terms of decile. Compared to the national sample, the sample for this evaluation was over represented by medium decile schools and under represented by low decile schools. These differences were statistically significant.
