ERO focused on two key areas in the evaluation:

Effective target setting. This was defined by three criteria:

- scanning achievement data

- targets building on previous year’s outcomes

- targets having ‘buy in’ from teachers and students. 

Effective actions. This was defined as:

- a plan focused on underachievement

- the school having more than 40 percent of targeted students making accelerated progress.

Further information about the methodology can be found in Appendix 2.
