Increases to the quantity of education — as measured for example by mean years of schooling — has, for a long time, been the central focus of policy makers and academic debate.
While increasing the access to education is important, the actual goal of providing schooling is to teach skills and transfer knowledge to students in the classroom.
This entry focusses on the outcomes of schooling — the quality of education.
While we have good empirical data on the access to education we know much less about the quality of education.
Unfortunately, the data on the skills and knowledge of students is sparse and has limited spatial and temporal coverage.
This is in part due to 3 3 and cost of creating and implementing standardized assessments that can be compared across borders and time.
Efforts to measure these outcomes are geographically more restricted often only OECD countries are included and even less is known about how the performance of students with respect to these outcomes has changed over time.
A third limitation is ссылка на продолжение measures are sometimes not comparable between countries.
While some assessments select children by Штроборез BOSCH GNF 65 A age, there are other assessments which select children by the school grade the child attends.
The aim of these studies is to test a адрес страницы random sample of the intended population.
The most widely available metric on the outcomes of education is literacy.
Data and research on literacy is discussed in detail in.
The Program for International Student Assessment PISA assessment, which is coordinated by the OECD, is the most well known international assessment of learning outcomes.
The first PISA study was carried посетить страницу in 1997 and since then it was repeated every three years.
The study is not select students by grade, but by age and only tests 15-year-olds, whatever their school level.
In a two-hour assessment the competencies in reading, mathematics and science of these students are assessed.
The coverage of PISA can be seen in on the results in the reading dimension, it obviously includes the richer OECD countries and unfortunately only few poorer countries.
Poorer countries are also not продолжить чтение regularly and were only participating in one round only and additionally it can be the case that for poorer countries not students from the entire country were selected, but instead only from particular regions.
PISA, as well as TIMSS, are standardizing their results so that the average score of students from OECD countries is 500 and the student standard deviation is 100.
Assuming a normal distribution of measurement outcomes this means 68% of OECD students are reaching scores in the range between 400 and 600.

It includes reasoning mathematically and using mathematical concepts, procedures, facts and tools to describe, explain and predict phenomena.
It assists individuals in recognising the role that mathematics plays in the world and to make the well-founded judgements and decisions needed by constructive, engaged and reflective citizens.
Results reported for China — — in fact are only based on four Chinese provinces: Beijing, Shanghai, Jiangsu and Guangdong.
These regions are not representative of China as a whole and there is every reason to expect that students from these provinces have access to better education than the average Chinese 15-year-olds.
The four regions are among the very richest regions of China and incomes are.
To describe the distribution of proficiency within countries PISA segments the achieved outcomes into levels 3 proficiency.
To achieve higher levels, students need to be able to solve tasks of increasing complexity.
The results are then reported as the share of the student population узнать больше здесь reached each level.
Where the top students are better than in other countries, the worst students are less bad than in other countries too.
The test scores of the worst and best performing students in each country are correlated as this visualization shows.
Countries in which the top students https://prognozadvisor.ru/bosch/akkumulyatornaya-batareya-dlya-bosch-2-607-336-333-2-607-336-863-2607336864.html better than top students in other countries tend to be the same countries in which the worst students also perform better than the worst students in other countries.
As the name says, TIMSS is an assessment of the mathematics and science knowledge of students.
As the closely linked PIRLS it is carried out by the International Association for the Evaluation of Educational Achievement IEA.
While PISA selects the assessed students by age and focusses on 15-year olds, TIMMS selects students by the grade they attend and tests students in Grades 4, 8, and in their final year.
TIMSS started slightly earlier than PISA.
The first TIMSS was conducted in 1995 and covered 45 national educational systems.
The coverage of TIMSS is similar to Источник статьи and includes mostly richer countries which are part of the OECD and only few poorer countries.
The coverage of TIMSS can be seen in on the results in the science dimension.
Precursors to TIMSS were already conducted from 1964 onwards.
The PIRLS is the other major study carried out by the International Association for the Evaluation of Educational Achievement Вот ссылка />Here the objective is to assess primary school students in reading proficiency.
PIRLS only started in 2001.

ASER is a report that is based on a survey of more than 500,000 children in rural areas across India.
It is not a school-based, but instead an in-home assessment of the reading and mathematical skills of children between 3 and 16.
The first ASER was carried out in 2005.
UWEZO is an adaptation of ASER carried out in three east African countries Tanzania, Uganda, and Kenya.
It has been done since 2009 and is carried out annually.
An assessment carried out by education ministries from fifteen southern and eastern African countries.
The study assesses students in grade 6 in the domains of reading and mathematics.
The first study was carried out in 1995.
There are several international standardised tests that try to measure learning взято отсюда in a systematic way across countries; but these tests are relatively new, and they tend to cover only specific geographical areas and skills.
One possible approach to learn from all these overlapping but disparate international and regional tests, is to put them on a consistent scale, and then pool them together across skills to maximize coverage across years and countries.
This is exactly what Nadir Altinok, Noam Angrist and Harry Patrinos did in a new working paper:.
They collected data from a large set of psychometrically-robust international and regional student achievement tests available since 1965, and they linked them together in a common measurement system.
Here we show some key charts using their data.
You can read more about their approach and results in our blog post.
A comparison of learning outcomes, country by country This chart plots GDP per capita after adjusting for differences in prices across countries and timeagainst average student test scores after homogenizing and pooling international and regional student assessments across education levels and subjects.
Each bubble in this chart is a country, where colours represent regions and bubble sizes denote population.
As we can see, learning outcomes tend to be much higher in richer countries; but differences across countries are very large, even among countries with similar income per capita.
The evolution of learning outcomes over time This scatter plot compares national average learning outcomes in 1985 and 2015 or closest years with available data.
Among these countries we see a broad positive trend: Most bubbles are above the diagonal line, which means the majority of countries have seen improvements in learning outcomes over the last couple of decades.
This is Диск Тормозной Задний A3/Octavia Ii/Vw Golf Iv/Touran Ii Bosch 0 986 479 great accomplishment!
It shows that policies matter and learning outcomes can, and often do improve.
The error margin on these differences is often 3, so small deviations from the diagonal line are not significant.
But it is worrying that many low-performing countries are substantially below the diagonal line.
Consider the comparison between Chile and Burkina Faso in the center of the chart: Both countries had similar average scores a couple of decades ago, but while Chile has improved, Burkina Faso has regressed.
You can check country by country trends over time in.
Student achievement beyond average scores This chart shows the share of students who achieve minimum proficiency i.
Here we see that those countries where a larger share of students attain minimum proficiency, tend to also be countries where a larger share of students attain advanced proficiency.
Better education lifts all boats.
Low-income, low-performing countries are clustered at the bottom of the global scale: the distribution of test scores within these countries is shifted down, relative to high-performing countries.
The challenges are therefore much larger in these countries.
Less than half of students 3 Sub-Saharan Africa reach the minimum global threshold of proficiency; and very, very few students achieve advanced skills.
Rich countries, on the other hand, tend to be less clustered.
For example, Belgium and Canada have roughly similar average outcomes; but Canada has a higher share of students that achieve minimum proficiency, while Belgium has a larger share of students who achieve advanced proficiency.
This shows that there is significant information that average scores fail to capture.
The database the authors published — 3 which is available on the — includes measure for 77 countries.
They extend earlier efforts by Hanushek and Kimko 2000 published in the American Economic Review.
In every country and in по этому сообщению year girls achieved higher PISA test scores in reading.
The difference of sometimes more than 50 points is substantial as the test scores are standardized to have a standard deviation of 100 points.
In mathematics the difference between girls and boys is much more mixed than in the reading dimension.
While in most countries boys tend to achieve better test scores there are also many countries and years in which girls performed better than boys.
Another interesting aspect of school performance is the effect 3 family environments and culture on students exam performance.
A study by John Jerrim finds that children of East Asian immigrants to Australia outperform their native counterparts in the PISA tests.
In mathematics, he finds them to be ahead by 100 посмотреть еще representing two and a half years of education.
This evidence suggests that the differences highlighted by PISA and the IEA may be driven by cultural or family factors rather than the schooling systems.
Indicators of 3 and knowledge, such as the OECD PISA scores, are highly correlated with indicators of economic development.
There exists a substantial literature on the effects of competition on school quality and performance.
Whether choice improves school quality remains an open question in economics.
On the demand side, parents need some way of observing school quality accurately as well as the ability to change schools.
Meanwhile, schools need some incentive to respond to any increase in competition.
This is especially important since most public school systems lack any profit 3 />Much of the research into the effects of competition rely on indirect measures of demand for high quality schools such as local rents 3 house prices.
Disaggregating the willingness to pay for better schools from neighbourhood effects and sociodemographic factors is highly technical and relies on models of sorting.
For more information on these models see Rothstein American Economic Review, 2006Bayer and McMillan NBER, 2005and Bayer et al.
An alternative approach has been to use variables correlated with school competition but independent of the other the demand and supply factors to disaggregate the different effects of choice instrumental variables approach.
For more information on this approach please 3 Hoxby American Economic Review, 2000 and Rothstein American Economic Review, 2007.
Recent research however suggests that the link between resources and school quality is not simple.
The OECD looked into whether money can buy stronger PISA test Музыкальный центр Pioneer />They concluded that the most important factor in PISA test performance is how resources are used: countries 3 prioritized the quality of teachers over class sizes performed much better.
This view represents a growing consensus in the education literature that inputs such as class size and expenditure per pupil have little to no effect on the returns to schooling in the developed world.
An argument made by Eric Hanushek and Ludger Woessmann читать полностью that the lack of any straightforward relationship between resources and school outcomes indicates a minimum resource requirement.
Once the resource threshold has been reached, additional expenditure has little or no returns to school quality — instead, teacher quality and other constraints matter far more.
The following scatter shows average spending per student from the age of 6 to 15 against reading test scores in 2009.
The education economists Eric Hanushek and Ludger Wößmann combined the results from educational achievement tests to investigate the question whether the quality of education has a causal influence on the growth of the economy.
The visualization shows the correlation between посмотреть еще quality of education, as measured by Ещё Холодильник Bosch KGN39X63 то and Woessmann, and the level of prosperity of the country in 2016.
