How can education help tackle rising income inequality?

The gap between the rich and poor has widened in OECD countries over the past 30 years. As the latest issue of the OECD’s new brief series Education Indicators in Focus describes, the average income of the richest 10% of people in OECD countries was about nine times greater than the income of the poorest 10% before the onset of the global economic crisis. This ratio was 5 to 1 in the 1980s.

What’s more, existing income inequality may also limit the income prospects of future generations in some countries. In countries with higher income inequality – such as Italy, the United Kingdom, and the United States – a child’s future earnings are likely to be similar to his or her father’s, suggesting that socio-economic background plays a large role in the development of children’s skills and abilities. Meanwhile, in countries with lower income inequality – like Denmark, Finland, and Norway – a child’s future income is not as strongly related to his or her family’s income status. In these countries, the development of children’s skills and abilities has a weaker link with socio-economic factors.

The implications for education policy are clear. Education policies focusing on equity in education may be a particularly useful way for countries to increase earnings mobility between generations and reduce income inequality over time. Countries can work towards this goal by giving equal opportunities to both disadvantaged and advantaged students to achieve strong academic outcomes – laying a pathway for them to continue on to higher levels of education and eventually secure good jobs.

Four top performers on the 2009 PISA reading assessment show the potential of this approach. Canada, Finland, Japan, and Korea all have education systems that put a strong focus on equity – and all have yielded promising results. In each of these countries, relatively few students performed at lower proficiency levels on the PISA reading assessment, and high proportions of students performed better than would be expected, given their socio-economic background.

Yet while each of these countries focuses on equity, they’ve pursued it in different ways. In Japan and Korea, for example, teachers and principals are often reassigned to different schools, fostering more equal distribution of the most capable teachers and school leaders. Finnish schools assign specially-trained teachers to support struggling students who are at risk of dropping out. The teaching profession is a highly selective occupation in Finland, with highly-skilled, well-trained teachers spread throughout the country. In Canada, equal or greater educational resources – such as supplementary classes – are provided to immigrant students, compared to non-immigrant students. This is believed to have boosted immigrant students’ performance.

Income inequality is a challenging issue that demands a wide range of solutions. In a world of growing inequality, focusing on equity in education may be an effective approach to tackle it over the long run.

How to read the chart: This chart shows the relationship between earnings mobility between generations of a family, and the prevalence of income inequality in different countries. Overall, countries with higher levels of income inequality tend to have lower earnings mobility between generations, while countries with lower levels of income inequality tend to have higher earnings mobility.

Helping immigrant students to succeed

by Marilyn Achiron

Whether in flight from conflict, with the hope of building a better life, or to seize a social or economic opportunity, people have been crossing borders for as long as there have been borders to cross. Modern means of transportation and communication, the globalisation of the labour market, and the ageing of populations in OECD countries will drive migration well into the next decades. Education is key to helping immigrants and their families integrate into their adopted countries. How are education systems adapting?

Results from PISA 2009 show that although native students generally outperform students with immigrant backgrounds, some countries have been able to narrow the performance gap between the two groups considerably—even as the proportion of immigrant students has grown.

The latest issue of PISA in Focus notes that the percentage of 15-year-old students with an immigrant background grew by two percentage points, on average, between 2000 and 2009 among OECD countries  with comparable data. Immigrant students now constitute more than 5% of the 15-year-old student populations in 13 OECD and partner countries and economies. In Ireland, New Zealand, Spain, the United States, and the partner countries Liechtenstein and the Russian Federation, the percentage of students with an immigrant background increased by five percentage points or more over the past decade, and these students now represent from 8% to 30% of these countries’ student populations.

During the same time period, a few countries narrowed the performance gap between native and immigrant students. In Belgium and Switzerland, for example, the performance gap shrank by nearly 40 score points, even though native students still outperform students with an immigrant background by 68 score points in Belgium and by 48 score points in Switzerland. And Switzerland was able to reduce the performance gap despite the fact that the percentage of students with an immigrant background rose during the period. Germany, New Zealand and the partner country Liechtenstein also show a narrowing of the performance gap between these two groups of students.

What these trends tell us is that there are ways that governments and schools can help students from immigrant backgrounds to overcome some of the disadvantages associated with that background. Often, students with an immigrant background are socio-economically disadvantaged. On average across OECD countries, the performance gap is reduced from 43 to 27 score points when comparing students of similar socio-economic status, regardless of whether they are from immigrant backgrounds or are native to the country in which they were tested.

But the fact that a 27-point performance gap–equivalent to well over half a school year–persists, even after accounting for socio-economic status, implies that other factors also have an impact on student performance. These may be related to whether the students were born in the country in which they were tested or elsewhere, or whether, when they’re at home, they speak the same language as that used in the PISA test. Yet given that the performance gap varies so widely across countries, even taking into account these other characteristics, and given that in some countries the performance gap has changed markedly over time, it is clear that public policy can make a difference to these students’ progress in school.
