I just thought this was an Interesting data point.

Australian primary school students have recorded their best ever results in an international maths and science assessment, curbing concerns about lockdowns disrupting learning.

The 2023 Trends in International Mathematics and Science Study (Timss), released by the Australian Council for Educational Research (Acer) late on Wednesday, analysed the skills of year 4 and 8 students.

About 14,000 students in Australia participated in the test across 500 diverse schools.

The report found Australian year 4 students, whose first years of schooling occurred doing Covid, ranked equal fifth internationally out of 58 countries, and equal 15th in mathematics.

I wonder if those scores will go up, down, or stay the same in following years? Can we place bets on this sort of crap?
