In 2014, over 3 million students in OECD countries – more than double the amount in 2000 – were studying outside their country of citizenship.

What makes some of the largest companies in the world successful? According to consultant Simon Sinek in a very popular TedTalk it is because they start with the ‘why’.

Two in three 15-year-old students earn money from work activity, and more than one in two hold a bank account.

Many education systems around the world are looking for ways to give parents more choice over where they send their children to school.

Why is it that even highly educated migrants to OECD countries are less likely to be employed than native-born adults who are similarly educated, even if the migrants have lived in their host country for several years?

As our world becomes increasingly interconnected, so do the risks we face. A disease breaking out in a village in Africa, a bank crashing on Wall Street or a protest in a distant country can all potentially “snowball” and influence the world financial, health or security order.

Unlike earlier PISA reports, the 2015 PISA report (Volume I and Volume II) highlights differences in sample coverage – how many students were eligible to participate in PISA – between countries.

As this month’s PISA in Focus reveals, students spend considerably more time learning in some countries than in others, but this does not necessarily translate into better learning outcomes.

Quality transitions that are well-prepared and child centred, managed by highly educated staff who are collaborating professionally, and guided by appropriate and aligned curricula, can go a long way to ensure that the positive impacts of early learning and care will last through primary school and beyond.

What do innovative learning environments around the world look like? How might they be led and evaluated? What policy strategies stimulate and support them? For the past decade the OECD’s Centre for Education Research and Innovation (CERI) has addressed these and similar questions in an international study called Innovative Learning Environments.

Back in 2013, when we launched the OECD's first international review of school resource policies, we may not have been fully prepared for the detective-type work we were getting into. The OECD Review of School Resources covers 18 school systems and aims to shed light on a part of education policy that has been surprisingly left in the dark.

Small in size but not in its ambitions, Slovenia has a bold vision for a society in which people learn for and through life, are innovative, trust one another, enjoy a high quality of life and embrace their unique identity and culture.

There is now a widespread consensus that high-quality early childhood education is critically important for children. Research continues to find that early childhood education can compensate for a lack of learning opportunities at home, and can help children begin to develop the social and emotional skills needed for success later in life.

Teachers enter the profession for a variety of reasons. Intrinsic motivations that have to do with the nature of the job and the intangible rewards associated with being an effective teacher play an important role.

The latest PISA in Focus tells some basic facts about bullying. First, bullying is widespread. Second, all types of students – boys and girls, rich and poor – face some risk of being bullied.

In August 2015, a newspaper published a story about Sam Cookney’s commute to work. Pretty boring, one would think, as long commutes are nothing new for most of us. However, Sam’s story is not so common. He works in London and commutes, several times per month, from Barcelona!

Interview with Matthew D’Ancona, political columnist for the Guardian and the New York Times

Costa Rica is recognised across Latin America as a leader in education. The country was among the first in the region to enrol all children in primary school and combat adult illiteracy.

Indigenous peoples are the first inhabitants of their lands, but are often poorly served by the education systems in their countries. Why? Is it necessary to wait until issues such as poverty or appropriate legal recognition for Indigenous peoples are resolved?

The challenge that youth are facing, first and foremost, is skills for employability. It is a fundamental issue. What we have realised in education is that going to school has not necessarily translated into quality learning.

Increasing the educational attainment of young adults has been the focus of much effort over recent decades. But we all know that having children spend more time in school does not guarantee that every student will learn.

Moving from the world of school to the world of work is one of the most dramatic changes in the lives of young people. And for many youngsters this transition does not go smoothly.

Tertiary qualifications have become the entrance ticket for modern societies. Never before have those with advanced qualifications had the life chances they enjoy today, and never before have those who struggled to acquire a good education paid the price they pay today.

Career decisions are wrought in complexities. Many students start by looking at their interests, selecting a career in line with their personal affinities or aspirations.

What happened in school today?” is a question that many parents across the world ask their children when they get home. Many parents also attend school meetings in order to understand how their child’s learning is developing.

Innovative schools challenge the boundaries – in time, space, and also in curricula and learning processes – that tradition seems to impose on schools today. They often have different approaches to the learning process and especially how its pedagogical core is organised.

Disadvantaged students don’t have as many resources at home as their advantaged peers so ideally schools would need to compensate by providing more support. However, often schools reinforce social disparities rather than moderate them.

It’s an exciting time for education in Wales. This was noted by the OECD earlier this year, when it recognised that government and sector are working closely together with a commitment to improvements that are “visible at all levels of the education system”.

Adults who lack basic skills – literacy and numeracy – are penalised both in professional and private life. They are more likely to be unemployed or in precarious jobs, earn lower wages, have more health issues, trust others less, and engage less often in community life and democratic processes.

Since Harvard economists Goldin & Katz published their ground-breaking book The Race between Technology and Education (2008), education has come face-to-face with the challenges of a world continuously altered by technological innovation. Education is generally perceived to be a laggard social system, better equipped to transmit the heritage of the past than to prepare for the future.

Teaching and learning lie at the heart of what it means to be human. While animals teach and learn from each other through direct demonstration, observation and experience, humans are unique in their ability to convey vast quantities of information and impart skills across time and space.

Diversity in the classroom includes differences in the way students brains learn, or neurodiversity. Diagnoses of neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention deficit hyperactive disorder (ADHD) have risen dramatically in the last two decades.

Anyone flying into Abu Dhabi or Dubai is amazed how the United Arab Emirates has been able to transform its oil and gas into shiny buildings and a bustling economy. But more recently, the country is discovering that far greater wealth than all the oil and gas together lies hidden among its people.

New technologies tend to shift jobs and skills. New technologies bring new products, which shift jobs across occupations: with the arrival of cars, the economy needed more assembly line workers and fewer blacksmiths.

Gender biases can be persistent. Too persistent. A simple exercise to illustrate the point: Picture a doctor or a professor. You will most likely think of a man. Now think of nurses and teachers and you are likely to imagine a woman. This unconscious gender bias is rooted in years of associating male and female attributes to specific roles in society. Inevitably, it also influences students’ career choices.

Late next month (21 November, to be exact) we’ll be releasing the results PISA’s first-ever assessment of students’ ability to solve problems collaboratively. Why has PISA focused on this particular set of skills? Because in today’s increasingly interconnected world, people are often required to collaborate in order to achieve their objectives, both in the workplace and in their personal lives.

Teaching is a demanding profession. Teachers are responsible for developing the skills and knowledge of their students, helping them overcome social and emotional hurdles and maintaining equitable, cohesive and productive classroom environments. On top of their teaching responsibilities, they are also expected to engage in continued professional development activities throughout their careers.

Skills have become the currency of 21st century economies and, despite the significant increase the UK has seen in university graduation over the last decade, the earnings of workers with a Master’s degree remain over 80% higher than those of workers with just five good GCSEs or an equivalent vocational qualification.

Higher education is one of the most globally integrated systems of the modern world. There still are important barriers to the international recognition of degrees or the transfer of credits, but some of the basic features of higher education enjoy global convergence and collaboration.

Taken as a whole, the OECD’s Programme for International Student Assessment (PISA) and Survey of Adult Skills (PIAAC) present a mixed picture for Korea and Singapore. As their economies have grown, these two countries’ education systems have seen fast and impressive improvements; both now rank among PISA’s top performers.

Successes and failures in the classroom will increasingly shape the fortunes of countries. And yet, more of the same education will only produce more of the same strengths and weaknesses.

It can be difficult to get your head around education finance. Who actually pays for it, where does the money come from, and how is it spent are all crucial questions to ask if you want to understand how the money flows in education.

Education plays a dual role when it comes to social inequality and social mobility. It is the main way for societies to foster equality of opportunity and support upward social mobility for children from disadvantaged backgrounds. But the evidence is overwhelming that education often reproduces social divides in societies, through the impact that parents’ economic, social and cultural status has on children’s learning outcomes.

In 2015, 193 countries committed to achieving the 17 Sustainable Development Goals (SDGs) of the United Nations, a shared vision of humanity that provides the missing piece of the globalisation puzzle. The extent to which that vision becomes a reality will in no small way depend on what is happening in today’s classrooms. Indeed, it is educators who hold the key to ensuring that the SDGs become a real social contract with citizens.

"Everyone believes in the atrocities of the enemy and disbelieves in those of his own side, without ever bothering to examine the evidence”, George Orwell wrote in 1943. And in an era of ‘fake news’ and post-truth, it resembles our world today.

Standardised testing has received a bad rap in recent years. Parents and educators argue that too much testing can make students anxious without improving their learning.

A university degree has always been considered as key to a good job and higher wages. But as the share of tertiary-educated adults across OECD countries has almost doubled over the last two decades, can the labour market absorb this growing supply of skills?

Looking – literally – at how teachers around the world teach can be a game changer to improve education. The evidence is clear that teachers are what makes the greatest difference to learning, outside students’ own backgrounds. It is widely recognised that the quality of an education system is only as good as the quality of its teachers. Yet we know relatively little about what makes a good and effective teacher.

The world’s growing complexity and diversity present both opportunity and challenge. On the one hand, globalization can bring important new perspectives, innovation, and improved living standards. But on the other, it can also contribute to economic inequality, social division, and conflict.

Over the last generation, it has become clear that something has gone awry in how the United States prepares its young people for life. In spite of millions of young people pursuing university education, fewer than one in three young Americans successfully attain a bachelor’s degree, while millions of good middle-skills jobs go begging.
