Reversing Australia’s declining achievement a shared problemResearch 11 Apr 2022 6 minute read
Data shows Australia’s declining performance on international student assessments is reflected in all of its school sectors.
In an article published in Teacher, ACER Deputy CEO (Research) Dr Sue Thomson compares Australia’s government, Catholic and independent schools in terms of student achievement and wellbeing, and other indicators of school climate, using data from the OECD Programme for International Student Assessment (PISA).
Dr Thomson says in 2018 – the most recent cycle of PISA for which results are available – mean reading literacy, mathematical literacy and scientific literacy achievement was highest among students in independent schools.
‘If we were dealing with a system in which students attended their school of choice regardless of sector, then these results would be quite clear. However, this is not the case. Government schools enrol the vast majority of students who fall into government-defined categories of disadvantage, such as low socioeconomic background,’ Dr Thomson writes.
Dr Thomson highlights that, after accounting for student-level socioeconomic background, the differences in mean scores between Australian school sectors are substantially reduced. After adjusting for socioeconomic background at both the student- and school level, few differences remain at all.
Performance over time by school sector can be analysed back to 2009, when Australia’s PISA National Advisory Committee first allowed reporting at the school sector level. Dr Thomson notes that, between 2009 and 2018, mean scores in reading, mathematical and scientific literacy have declined over time for all Australian school sectors. The declines in government schools were smaller than in Catholic and Independent schools.
‘The decline in Australia’s PISA scores is a complex problem, necessitating complex and varied solutions. What is evident from these data, however, is that the decline in scores cannot be attributed to one particular school sector, but it is shared across the whole system,’ Dr Thomson writes.
Dr Thomson’s article also presents data from the PISA student, teacher and principal questionnaires in relation to three aspects of school climate that research has found to be associated with achievement: student sense of belonging, bullying and teacher behaviour hindering learning.
‘Students reporting a strong sense of belonging tend to show higher academic motivation, self-esteem and achievement,’ Dr Thomson writes. ‘Australian students, on average, have a lesser sense of belonging than students on average across OECD countries.’
Between 2012 and 2018, the percentage of students agreeing to the positive statements about sense of belonging, such as ‘I feel like I belong in school’, decreased significantly in all school sectors, and the percentage agreeing to the negative statements, such as ‘I feel lonely at school’, increased significantly. For all school sectors the largest change was for ‘I feel like an outsider (or left out of things at school)’, which increased by 14 percentage points for government schools, 11 percentage points for Catholic schools, and 10 percentage points for independent schools.
In all Australian school sectors, student reports of exposure to bullying at school was higher than the OECD average. The proportion of students who reported that on a regular basis, ‘other students made fun of me’, ‘I was threatened by other students’, and ‘I got hit or pushed around by other students’ increased in all sectors between 2015 and 2018.
Dr Thomson explains that PISA asks principals to report on the extent to which student learning in their school is hindered by particular teacher behaviours, such as teachers being unprepared for class and teachers resisting change. The biggest changes over time were in the area of teacher absenteeism. Between 2012 and 2018, teacher absenteeism increased by six percentage points in government schools, eight percentage points in independent schools, and nine percentage points in Catholic schools.
‘If Australia is to have any hope of improving scores on international assessments then the underlying health of the whole system needs to improve,’ Dr Thomson writes. ■
