ERO's evaluation status analysis for schools

 ERO’s evaluation status analysis for schools

From 1 July 2012 to 30 June 2017, ERO has conducted more than 3,700 evaluations of state (and state-integrated) primary, intermediate and secondary schools. Over that time, the number of schools across the country has varied between 2,400 and 2,500. This means many schools have had more than one evaluation in the five year period and a small number of poor performing schools have had three ERO evaluations during that period.

The graphs below show the total evaluation outcomes from all evaluation categories over the 5 year period.

A breakdown of all school evaluations by ERO evaluation category and outcome is provided on the following page. For the purpose of this analysis, information about primary/intermediate schools and secondary schools has been shown separately. The secondary school category includes composite schools with students in Year 9 and above, teen parent units and other special units catering for young adult learners.


Over the period, about 68 percent of the evaluations under the 1-2 year review category found that the school’s performance had improved sufficiently for it to be moved to the 3 year return category. However, almost a third of these 1-2 year reviews lead to a continuation of the 1-2 year review process for the schools concerned.

About 77 percent of the 3 year reviews resulted in no change in status for the schools with the next review scheduled in another three years’ time. For about 12 percent of these reviews the school showed sufficient progress to be moved to the 4-5 year return category. Ten percent were assessed as needing to move down to the one to two year return cycle.

In the 4-5 year category, 54 percent (209 out of 402 school evaluations) led to another decision by ERO to return in four to five years. The rate for secondary schools was higher than in primary schools. Conversely, 45 percent (181 schools) did not sustain their performance to a level which warranted maintenance of the four to five year return and a decision was taken to return in three years. Unfortunately, 10 schools (about 2 percent of this group) had struggled with material issues and were moved from the four to five year cycle down to the one to two year cycle.

Position at July 2017

There were 190 schools were in ERO’s 1-2 year review category, and 500 schools were in the 4-5 year return category.

Based on school roll data from the Ministry of Education the 190 poor performing schools have a combined roll of around 34,000 students while the 500 schools most recently assessed as performing very well have a combined roll of about 267,000. A total of 455,000 students attend schools in the 3 year return category.
