Challenges
15% migrant background > OECD 11.2%
High concentration in disadvantaged schools (23%)
• Cannot explain decline in Sweden overall results. Policies in
place: Swedish reception classes; additional $$; NAE
programmes
Funding is unequal partly due to decentralisation.
Policy responses
• to ensure that they are effectively targeted to education and respond to
equity and quality objectives,
Review current funding mechanisms
• are evaluated and followed up for effectiveness.
Ensure funding strategies
• to local authorities to enhance their capacity to design and deliver
programmes that target equity.
Provide support
• The type of mechanism used reflects the degree of budget autonomy given to the
different administration levels and given policy priorities. Funding of school education
can be :
– Specified for particular purposes [Earmarked grants] (e.g., teacher salaries, support
for students with SEN, transportation to school)
– Weighted student funding schemes are based on two main elements: funding
follows the student on a per-student basis and this amount depends on the social
characteristics and educational needs of each student
– Discretion of lower levels of administration, as long as they are dedicated to
specific cost types [Block grants and restricted block grants] (e.g., non-teacher staff
salaries, operating costs)
– Discretion of lower levels of administration that decide how to allocate funds to
other levels of administration/ schools [Lump sum transfer]
• Allocation mechanisms relying on transparent funding formulas can play a critical
role in promoting greater efficiency and equity
Countries use a mix of various allocation mechanisms
Establish guiding principles when designing funding formulas to
distribute resources to individual schools
Align funding formulas with government policy and establish evaluation
criteria accordingly (e.g., efficiency, equity, transparency, sensitivity to
local conditions)
Reflect different per student costs in the provision of education, while
addressing equity challenges (allocate funds weighing additional costs of
specific educational provision or location, student supplementary needs)
Set incentives for budgetary discipline
Ensure periodic review and evaluation of funding formulas
Some principles
• Manage the risks of needs-based or input allocation mechanisms
– Avoid excessive labelling of students (can be stigmatising for individuals and
lead to cost inflation)
– Apply transparent and impartial criteria for assessing students having
physical/learning impairments
– Incentivise school boards and school communities to scrutinise provision for
students with SEN and its impact on their learning
• Share experience about funding formulas developed at sub-national levels for
system learning
– Avoid duplication of efforts by sharing knowledge
– Identify and promote best practices in funding allocation across the system,
through central-level initiatives

assessments
• Schools practicing selective admission tend to attract students
with higher ability and socio-economic status, regardless of
their educational quality
• Given that high-ability students are less costly to educate and
can increase a school’s attractiveness to parents, controlling
their intake can provide schools with a competitive advantage
– Allowing private schools to select their students therefore provides
them with an incentive to compete on the basis of exclusiveness
rather than their value added, which can undermine the dynamics of
competition diminish the positive effects it may otherwise have on
quality.
• Selective admission also a source of increased stratification.
Selective admission
• Student sorting occurs not only based on explicit
admission criteria but also based on parental self-
selection, selective expulsion and more subtle
barriers to entry.
– Policies seeking to reduce segregation should therefore
also identify and address overly complex application
procedures, expulsion practices, information deficits and
other factors that prevent some students from exercising
school choice.
Selective admission
• Across 18 education systems where parents in PISA
were asked why they choose a school parents were
more likely to consider important or very important
that:
– there is a safe school environment, that the school has a
good reputation and that the school has an active and
pleasant climate – even more so than the academic
achievement of the students in the school.
Parental choice – outcomes often don’t come first
• Parents whose children attended disadvantaged
schools considered distance more important
– And children of parents who assigned more importance to
distance scored lower in PISA
• Students whose parents considered low expenses
important scored worse
– And in most countries the parents of children attending
disadvantaged and public schools were more likely to
consider low expenses important
Parental choice – social background matters
Challenges for Sweden
Open school choice : first come first served.
Growing segregation no better results.
Free schools not fully integrated in
education planning.

Revise school-choice arrangements
• to ensure a more diverse distribution of students in schools.
Introduce controlled choice schemes
• To encourage a culture of collaboration and peer learning, consider
defining national guidelines to ensure that municipalities integrate
independent schools in their planning, improvement and support
strategies.
National guidelilnes
• about schools and support them in making informed choices
Improve access to information
• As of 2009, 9 out of 22 OECD countries with available
data facilitated the attendance of government-
dependent private primary schools with vouchers.
– In five of these, the voucher programme was restricted to
students with lower socio-economic background.
• At the lower secondary level, 11 out of 24 countries
reported to operate voucher schemes,
– 7 of which targeted disadvantaged students.
Voucher policies
• Vouchers that are available for all students can help to expand the choice
of schools available to parents and promote competition among schools.
• School vouchers that target only disadvantaged students can help improve
equity in access to schools.
• PISA data show that, when comparing systems with similar levels of public
funding for privately managed schools, the difference between the socio-
economic profiles of publicly managed schools and privately managed
schools is twice as large in education systems that use universal vouchers
as in systems that use targeted vouchers
• Regulating private school pricing and admission criteria seem to have a
positive impact on the ability of voucher schemes to go hand in hand with
limited social inequity
Impact of voucher policies
Examples of systems with high levels of school choice
• Parents and students get to
choose up to four schools from a
list of schools in their geographical
area.
• Inter-Network Enrolment
Commission, steers the selection
process, allocates students
according to their priorities, and
weighted geographical and
educational criteria.
• Awards 80% of the places by the
ranking, while ensuring that the
remaining places are awarded to
students from disadvantaged
primary schools.

Editor's Notes
We did our last PISA assessment of learning outcomes in science in 2006, and it was a quite different world then.
It is hard to imagine but we did not have the iphone then. Twitter was still a sound, Skype for most people was a typographical error in those times, the amazon was still a river, there was no android, no video streaming.
But science learning outcomes in the industrialised world remained entirely flat during those years.
And the world moved on, streetmaps became dynamic,
cars became electric and started to drive automatically, drones started to fly, and crowdfunding hugely amplified the potential of each of us individually and of us collectively.
But again, this did not translate into improved learning outcomes.
And in just the last few years, so many things have happened, virtual reality brought the whole world to each of us in real time, 3D printers can produce right where we are, robotics is changing the lives of people, or think about big data, the cloud, biogenetics and our capacity to affect life as such.
But science performance of students remained unfazed by all of this.
When you see that, you might be tempted to drop the idea of improving education, as an agenda that is too big, too complex and too politically charged and too entrenched in vested interests to warrant real progress.
But dont give up yet, the PISA data also show some amazing success stories.
Portugal kept moving on from poor to adequate, despite a difficult financial crisis.
Singapore kept advancing from good to great.
The UK held its ground.
So there is hope
But then, doing well in science is only part of the story. Here you see the share of students who want to go on to a science career, so students who see science as opening life opportunities.
And while students in Vietnam do well in science, they dont relate science to their future lives. So something is missing here.
And the same is true for other high performing education systems too.
Conversely, students in the United States are keen on a science career, but they dont have the skills to realise their dreams.
So do we have to choose between good outcomes and strong motivation?
The point is that we have to get several things right to speak of a good education.
Success in science is about performance,
but its also about having students trust in the methods of science
And about students wanting to pursue science in their own lives.
Singapore is a country that gets all of that right, and at a lower level you can see that also in …
Chinese Taipei…
Without confidence intervals
Or consider this chart. Here you see student learning outcomes by decile of social background. The red square signals the performance of the 10% most disadvantaged students in the Dominican Republic, and the green triangle the performance of the 10% most privileged students in that country. So there is a big achievement gap in the Dominican Republic. And people who see this often conclude that poverty is simply destiny.
But when you look at this across countries, you can see how students from similar social backgrounds show very different performance levels depending on the country where they go to school.
Consider that the learning outcomes among the 10% most disadvantaged students in Viet Nam compared still favourably to the average student in the Western world. Consider that in most countries we find educational excellence among some of the most disadvantaged schools. And consider that many of the world’s leading education systems have not held this position since long. So it can be done.
Policy action 1.4: Revise school choice arrangements to ensure quality with equity. Improve disadvantaged families’ access to information about schools and support them in making informed choices. In addition, introduce controlled choice schemes that combine parental choice and ensure a more diverse distribution of students at schools. Consider defining national guidelines to ensure that municipalities integrate independent schools in their planning, improvement and support strategies to encourage a culture of collaboration and peer learning.
School choice is common in the Netherlands, with control applied at the local level to mitigate imbalances in school composition or weighted student funding to support greater social diversity in schools. In Nijmegen, a central subscription system to assign students exists for primary schools, to reach a share of 30% of disadvantaged students in each school. All the primary schools have agreed on a central subscription system, based on the distribution of students in different categories. In the event of oversubscription, priority is given to siblings and children who live nearby. In order to reach the required balance, subsequent priority is given to either advantaged or disadvantaged students by a lottery system (Musset, 2012). The National Knowledge Centre for Mixed Schools (Kenniscentrum Gemengde Scholen) produces knowledge and influences work on school choice. This centre also provides procedures for school choice and information on the topic to parents (OECD, 2015b).
In the Netherlands, school budgets depend on enrolment and vary according to demand, but students from less privileged backgrounds receive more public money. This scheme was adopted for all primary schools in the Netherlands in 1985, and schools with substantial numbers of weighted students received more funds. Once the level of funding for each school is determined, based on the need of individual students, there is no requirement that schools use these extra resources directly for these students. They can, for example, choose to reduce the number of students per class. The weighting for each student is determined by his or her parents’ educational level (Musset, 2012). Empirical research conducted by Ladd and Fiske (2011) shows that this system succeeded in distributing differentiated resources to schools according to their different needs: primary schools with a high proportion of weighted students have, on average, about 58% more teachers per student, and also more support staff.
Similarly, the Chilean education system adopted a weighted voucher system in 2008, providing an extra per-student subsidy for disadvantaged students. The voucher for children with low socio-economic status and indigenous children is 50% higher than for children that are not considered priority. Financing schemes like this provide the right type of incentives for schools to enrol more disadvantaged children and therefore reduce segregation. They can also mitigate the stratifying effects of unrestrained universal voucher programmes (Elacqua, 2009).
