Poverty and the perception of poverty–how both matter for schooling outcomes


Socio-economic disadvantage is a challenge to educators everywhere

poverty-schoolCompensating for students’ socio-economic disadvantage is one of the greatest challenges facing teachers,school leaders and education systems as a whole. However, data from PISA show that some countries are much better at this than others.

Consider the chart above. The horizontal axis shows the percentage of lower secondary teachers who work in schools where their principal reported that more than 30 percent of students in their school were from disadvantaged homes.1

The vertical axis shows the actual percentage of 15-year-old students from disadvantaged homes, measured by PISA’s internationally standardized index that summarizes various indicators of socio-economic disadvantage, including parents’ income and education level, educational resources at home, and other family possessions.2 In other words, the horizontal axis reflects school principals’ perception of disadvantage by national standards while the vertical axis reflects the prevalence of disadvantage as compared internationally.

Brazil, Chile, Malaysia, Mexico and Portugal are found in the upper right corner of the chart because their schools have a large share of disadvantaged children and that aligns with the reports of principals. The lower left corner includes the Czech Republic, Denmark, Finland, Iceland, Japan, Korea and Norway where disadvantage in schools is limited, and fewer than one in ten principals reports significant disadvantage.3 These are the results one would expect.

But actual disadvantage and principals’ perceptions of disadvantage don’t always align: 65 percent of principals in the United States say that more than 30 percent of their students are from disadvantaged homes, far more than in any other country. However, the actual percentage of disadvantaged students reported by PISA is just 13 percent, marginally higher than in Japan and Korea; but in those two countries, only 6 percent and 9 percent of principals, respectively, report a comparable share of disadvantaged students in their schools.

In other words, the actual incidence of child poverty is roughly the same among these three countries, but more than six times as many US principals reported that more than 30 percent of their students are disadvantaged. Conversely, in Croatia, Serbia and Singapore, more than 20 percent of students are disadvantaged, while 7 percent or fewer principals report significant populations of disadvantaged students.

Obviously, a child considered poor in the United States may be regarded as relatively wealthy in another country, but the fact that the perceived problem of socio-economic disadvantage among students is so much greater in the United States – and in France too – than the actual backgrounds of students also suggests that what school principals in some countries consider to be social disadvantage would not be considered such in others.

And there is a third important dimension, namely the actual impact of disadvantage on learning outcomes, which is shown by the size of the circles in the chart.4 That impact reflects whether an education system provides equitable learning opportunities. In countries like Finland, Iceland and Norway, one would expect this impact to be small because these countries have very little socio-economic disadvantage in their student populations. Achieving equity in school is easy when society distributes wealth and family education equitably.

But the more impressive examples are countries like PISA top-performer Singapore, where disadvantage is significant, but its impact on learning outcomes is only moderate. These countries seem very good at nurturing the extraordinary talents of ordinary students and at ensuring that every student benefits from excellent teaching.

In contrast, France has a comparatively small share of disadvantaged students, but school principals perceive this share to be large, and student learning outcomes are closely related to social background – more closely, in fact, than in any other country except Chile and the Slovak Republic. More generally, the results show that principals’ perception of disadvantage correlates with inequalities in education opportunities more strongly than real disadvantage does.

There is another way of looking at this: In Korea and Singapore, more than one in two students from the bottom quarter of the socio-economic spectrum score among the most proficient quarter of the world’s students on PISA; in Japan, 45 percent of disadvantaged students are similarly “resilient” and perform better on the PISA test than their backgrounds would predict. By contrast, in France and the United States, only around 20 percent of students are resilient, and in Israel, just one in 10 is.

So what does all this mean? Socio-economic disadvantage is a challenge to educators everywhere, but in countries like France and the United States, perceived disadvantage is far greater than real disadvantage and it makes a significant difference for student performance. In countries like Singapore, real disadvantage is far greater than school principals’ perception of it, but Singapore’s schools seem to be able to help their students overcome that disadvantage.

1. Or more precisely, the percentage of lower-secondary teachers in schools whose principals reported that more than 30 percent of students are from disadvantaged homes. Data are based on the OECD Teaching and Learning International Survey (TALIS), which is representative of the teaching force in the participating countries.

2. Referred to as the OECD Programme for International Student Assessment (PISA) index of economic, social and cultural status (ESCS).
3. Significant here means more than 30 percent of students from disadvantaged homes in the school.
4. Measured here by the percentage of variation in mathematics performance that is explained by the PISA index of economic, social and cultural status (ESCS).
