Notes to Table A.7
1: The headline PISA score.
2: The headline score adjusted for social background, by comparing the scores between countries for students on the ESCS mean
3: The amount of variation in score explained by social background.
4: The amount that the average score changes with social background - a lower score implies less change as background changes.
5: The mean score for non-immigrant-background pupils (with both parents born in the country of the test) minus the minus score for immigrant-background pupils. A negative figure implies that immigrant-background pupils score better.
