More than compilations of statisticsDo we understand the policy objectives
What countries care about, what they intend to do about it and how they define success
Do we understand the policy context and can we anticipate its future development ?
Do we understand the strategic requirements for change?
Are these
Technically feasible?
Politically and socially suitable?
Robust and cost-effective?
Do we understand the delivery challenge and delivery capacity?
Nature and size of the barriers that systems face to deliver reform goals
Can what works in one country by done in another by real people in real situations?
Avoiding big time and energy traps?
Do we understand past and present performance vis a vis the policy goals as well as the drivers of performance and their underlying system activities?

Editor's Notes

  • #5 Such an OECD knowledge base needs to reflect three dimension, (1) an understanding of what countries are trying to achieve, (2) the evidence that we have, and (3) what we know about policy delivery in different contexts. As concerning the policy context: Do we understand what countries care about, what they intend to do about it and how they define success? Do we understand the policy context, and that is not just about the context as it stands, but how we anticipate its future development, because in an area like education where the delivery chain of reforms is so long, we need to think far into the future. Do we understand the strategic requirements for change, and do we judge various approaches to change technically feasible? And not everything that is feasible is politically suitable. And not everything that can be done is robust and cost-effective. With regard to the evidence: Are our indicators and analyses adequately capturing past and present performance of the education system vis a vis the reform goals, and have we been able to pin-point the drivers of performance and their underlying system activities? How does what we produce at the OECD, whether that is data, country reviews or thematic review relate to and add value to what other players provide?Finally, to what extent is our analysis useful and actionable in national contexts. Do we understand the challenges for reform delivery in countries and their delivery capacity? Is what we propose doable by real people in real situations and avoiding big time and energy traps?
  • #6 The pace of change is most clearly visible in higher education, and I want to bring two more dimensions into the picture here. Each dot on this chart represents one country. The horizontal axis shows you the college graduation rate, the proportion of an age group that comes out of the system with a college degree. The vertical axis shows you how much it costs to educate a graduate per year.
  • #7 *Lets now add where the money comes from into the picture, the larger the dot, the larger the share of private spending on college education, such as tuition.The chart shows the US as the country with the highest college graduation rate, and the highest level of spending per student. The US is also among the countries with the largest share of resources generated through the private sector. That allows the US to spend roughly twice as much per student as Europe. US, FinlandThe only thing I have not highlighted so far is that this was the situation in 1995. And now watch this closely as you see how this changed between 1995 and 2005.
  • #8 You see that in 2000, five years, later, the picture looked very different. While in 1995 the US was well ahead of any other country – you see that marked by the dotted circle, in 2000 several other countries had reached out to this frontier. Look at Australia, in pink.
  • #14 Thatwasallveryquick, letusgothroughthisdevelopmentonceagain
  • #25 The best way to find out whether what students have learned at school matters for their life is to actuallywatch what happens to them after they leave school. This is exactly what we have done that with around 30,000 students in Canada. We tested them in the year 2000 when they were 15 years old in reading, math and science, and since then we are following up with them each year on what choices they make and how successful they are in their transition from school to higher education and work.The horizontal axis shows you the PISA level which 15-year-old Canadians had scored in 2000. Level 2 is the baseline level on the PISA reading test and Level 5 the top level in reading.The red bar shows you how many times more successful someone who scored Level 2 at age 15 was at age 19 to have made a successful transition to university, as compared to someone who did not make it to the baseline PISA level 1. And to ensure that what you see here is not simply a reflection of social background, gender, immigration or school engagement, we have already statistically accounted for all of these factors. The orange bar. …How would you expect the picture to be like at age 21? We are talking about test scores here, but for a moment, lets go back to the judgements schools make on young people, for example through school marks. You can do the same thing here, you can see how well school marks at age 15 predict the subsequent success of youths. You see that there is some relationship as well, but that it is much less pronounced than when we use the direct measure of skills.
  • #26 Let us go back to the 1960s. The chart shows you the wealth of world regions and the average years of schooling in these regions, which is the most traditional measure of human capital. Have a look at Latin America, it ranked third in wealth and third in years of schooling, so in the 1960s the world seemed pretty much in order.
  • #27 But when you look at economic growth between 1960 and 2000, you see that something went wrong. Despite the fact that Latin America did well in terms of years of schooling, only Sub-Saharan Africa did worse in terms of economic growth. So in 2000, Latin America had fallen back considerably in terms of GDP per capita.You can draw two conclusions from this: Either education is not as important for economic growth as we thought, or we have for a long time been measuring the wrong thing.
  • #28 Now let me add one additional element, and that is a measure of the quality of education, in the form of the score of the different world regions on international tests like PISA or TIMSS. And you see now that the world looks in order again, there seems a close relationship between test scores and economic growth. You can see that even more clearly when you put this into graphical form. This is one of the charts produced by Professor Hanushek. And, as Professor Hanushek will explain, the relationship holds even when you account for other factors, it even holds when you compare growth in economies with growth in learning outcomes, which is the closest we can come to examining causality.So what this tells you is that it is not simply years of schooling or the number of graduates we produce, but indeed the quality of learning outcomes that counts.
