100 = Peer Median
Each Index is centred on 100, representing the median performance of the relevant peer group.
How it works
GAUGED organises, standardises and benchmarks information from different sources within one coherent assessment.
Methodology note: Some GAUGED measures are nationally comparable proxies derived from published data. For example, Implied Teacher Contact Ratio is derived from published pupil-teacher ratio and average class size data; it is not a timetable-derived ICFP contact ratio. Relevant product pages explain these definitions where they are used.
Each Index is centred on 100, representing the median performance of the relevant peer group.
The reasons for a difference still require context, professional judgement and, where appropriate, further investigation.
