I'm not familiar with the Australian education system or this study's design, but at first glance, this quote

>The report, commissioned by the Alliance of Girls’ Schools Australasia, was conducted by Macquarie Marketing Group using OECD data

reads more to me like "we found that all-girl private schools are better than the average of public and private schools", and the obvious reason why is probably *because they're private schools*, and not because they're all-girl.

Same pattern in UK state schools

Same comment as above. From your article:

> there are some underlying factors skewing these results, such as: > * grammar schools are more likely to be single-sex > * co-educational schools have a higher proportion of poorer pupils > * girls are more likely to get good results

The original statement which I replied to was an absolute position. These examples invalidate it.

Also note that both of your comments show that people in a position to choose, are choosing single sex schools for their daughters and getting better outcomes on average.

Lastly, while the article mentions some caveats around selective state schools, the other side of that is the UK has many single sex comprehensive schools. We should not ascribe too much weight to the caveat.
