What's ICSEA and how does it relate to school quality?
ICSEA (Index of Community Socio-Educational Advantage) measures the socio-economic background of a school's community. Average is 1000. Elite private schools typically score 1180-1230. ICSEA correlates strongly with academic outcomes, but it measures family advantage, not school teaching quality. To assess teaching quality, look at "value-added" data (how much the school improves students above their starting point), Education Department websites publish this. A school with ICSEA 1200 should produce strong results; a school with ICSEA 1100 producing strong results is doing more impressive teaching.
