We score performance in tests and create an index value. The Aggregated Index Value is the sum of the test results. It gives us a way to compare performance between years, sectors and regions, since a higher AIV represents a greater measured capability and performance. Our benchmarking reveals that performance has markedly improved in most areas over time
