Review officers entered information into an electronic synthesis sheet for each school. This included qualitative information for most questions, and ratings for selected questions.  The ratings were moderated by a team of experienced evaluators to cross-check that judgements had been applied in a consistent manner. Where necessary, adjustments were made to the ratings.
Data were analysed in a range of ways. Qualitative information was coded by themes and quantified to ascertain the magnitude of the findings. Qualitative analysis was also undertaken using NVivo.  For example, analysis was conducted on the practices of the schools that had high ratings for certain questions. Quantitative analysis was carried out to see if there were any significant differences in findings by demographic characteristics such as school type, decile, location, and roll size.
