In an article in the NYTimes that focuses mainly on Shanghai’s stellar results we find a table, and in that table we find NZ’s education test results. This is the PISA test of 15 year olds. I’ve often said that NZ has a good average education, while the USA has a much wider distribution, and a lower average. This bears some of that out.
Obviously we’d be much better off further up the table, especially for mathematics.
