2020 is likely to go down in the history books as a memorable year, if not an easy or relaxing one for those involved in education. Between the fires, floods and the COVID-19 pandemic, there have been many interruptions to learning and cancellations of gathering to celebrate milestones such as birthdays and anniversaries. This Special Issue represents our socially distanced celebration of the coming together of two educational milestones – the 90th birthday of the Australian Council for Educational Research (ACER) and the publication of the latest results from the Programme for International Student Assessment (PISA) representing more than 20 years of participation by Australian students and schools in this international study.

2020年很可能会成为历史上令人难忘的一年，即使对于那些从事教育的人来说，这不是一个轻松或轻松的一年。在大火，洪水和COVID-19大流行之间，学习受到许多干扰，取消了庆祝生日和周年纪念日等重要里程碑的聚会。本期特刊代表了我们在社会上遥遥相庆的两个里程碑式的庆祝活动：澳大利亚教育研究理事会（ACER）诞辰90周年，以及国际学生评估计划（PISA）最新成果的发表，这些成果代表了超过澳大利亚学生和学校参与这项国际研究已有20年。
