Education at a Glance 2025: Bulgaria
Table of contents
This country note provides an overview of the key characteristics of the education system in Bulgaria based on data from Education at a Glance 2025. In line with this year’s thematic focus, it emphasises tertiary education while also covering other parts of the education system. The data in this note are provided for the latest available year. Readers interested in the reference years for the data should refer to the corresponding tables in Education at a Glance 2025.
The share of young adults (25-34 year-olds) without upper secondary attainment continues to decline across the OECD, reaching an average of 13%. This trend also continues in Bulgaria, where the share fell from 18% to 12% between 2019 and 2024.
Individuals with greater educational attainment generally face a lower risk of unemployment and earn higher wages. Completing upper secondary education is particularly important in reducing the risk of unemployment. On average across the OECD, 12.9% of economically active young adults (25-34 year-olds) without an upper secondary qualification are unemployed, compared to 6.9% of those with upper secondary or post-secondary non-tertiary attainment. Those who go on to gain a tertiary qualification see a relatively smaller further reduction in unemployment, with 4.9% of tertiary-educated young adults unemployed on average across the OECD. This pattern is similar in Bulgaria (albeit at a higher level): 17.8% of young adults without an upper secondary qualification are unemployed, compared to 5.1% of those with upper secondary or post-secondary non-tertiary attainment and 2.4% of those with tertiary attainment (Figure 1).

On average, individuals with a master’s or equivalent degree have significantly higher employment rates and earnings than those with a bachelor’s or equivalent degree. However, the share of young adults (25-34 year-olds) attaining a master’s or equivalent qualification varies widely across OECD countries, ranging from 1% to 39% in 2024. In Bulgaria, 22% of 25-34 year-olds hold a master’s or equivalent degree, which is above the OECD average of 16%. This represents an increase since 2019, when the share was 19%.
The average wage gap between individuals (25-64 year-olds) with and without upper secondary educational attainment is relatively modest across OECD countries. On average across the OECD, workers without upper secondary qualifications earn on average 17% less than those who have completed upper secondary education, while workers with tertiary attainment earn 54% more than those with upper secondary attainment. In Bulgaria, the wage gap between workers with and without upper secondary attainment is larger than the OECD average, at 29%. The gap between those with upper secondary and tertiary attainment is also larger than the OECD average, at 76%. This suggests a generally more dispersed wage distribution by educational attainment in Bulgaria, which may indicate higher relative returns to education but also a higher level of income inequality compared to the OECD average.
Education systems must adapt to changes in the number of children by expanding or reducing provision accordingly. In many countries, the population of children aged 0-4 changed significantly between 2013 and 2023 and is projected to change further by 2033. Bulgaria experienced a decline of 17% in the number of 0-4 year-olds, and is projected to see a decline of 16% between 2023 and 2033.
The share of students in lower secondary education who are at least two years older than the expected age for their grade varies widely across OECD countries, ranging from virtually none in some countries to over 10% in others. In Bulgaria, the share is in the middle of the OECD distribution in 2023, at 3.8%.
Bachelor’s or equivalent programmes are the main entry point into tertiary education in most OECD countries, with an average of 78% of those starting tertiary education for the first time enrolling in such programmes. In Bulgaria, the share is even higher at 86%.
Women make up the majority of first-time entrants to tertiary education in most OECD countries. In Bulgaria, they accounted for 54% of first-time entrants in 2023, up from 51% in 2013. Across the OECD, women make up 54% of new entrants on average, the same share as in 2013.
Across the OECD, the two most popular broad fields of study are science, technology, engineering and mathematics (STEM) and business, administration, and law, each accounting for 23% of graduates from bachelor’s or equivalent programmes. They are closely followed by the broad field of arts and humanities, social sciences, journalism and information, at 22% of graduates. In Bulgaria, 24% of bachelor’s degree students graduate from a STEM field, 21% from business, administration and law, and 21% from arts and humanities, social sciences, journalism and information.
International student mobility in tertiary education continues to rise across the OECD, with some countries experiencing substantial growth in the share of international students between 2018 and 2023. On average, 7.4% of all tertiary students across the OECD were international or foreign students, compared to 6% in 2018. Bulgaria saw an increase, with the share rising from 6.4% to 8.7% (Figure 2).

There are significant disparities in how much governments spend each year in education across OECD, partner and accession countries. Bulgaria spends USD 7 397 per student from primary to post-secondary non-tertiary levels, placing it at the lower end of the country range, which spans from less than USD 2 000 to more than USD 27 000 (Figure 3).

As in most other countries, government expenditure in Bulgaria is higher at tertiary level, including research and development (R&D), than at primary to post-secondary non-tertiary levels. Government expenditure in Bulgaria amounts to USD 8 198 per tertiary student compared to the OECD average of USD 15 102.
A large part of the disparity in expenditure per student across OECD, partner and accession countries reflects differences in national income levels. When expenditure is measured as a share of GDP, cross-country differences tend to be smaller, ranging from 2.5% of GDP to 6.9%. In Bulgaria, education investment in primary to tertiary education stands at 3.3% of GDP, which is below the OECD average of 4.7% by this measure.
Governments are the primary source of education funding in all OECD countries, especially for the levels covered by compulsory education. In Bulgaria, governments provide 95.2% of total funding for primary, secondary, and post-secondary non-tertiary education (before transfers to the private sector), which is above the OECD average of 90.1%. At the pre-primary and tertiary levels, private funding often plays a larger role. In Bulgaria, 99% of pre-primary education funding (after transfers) and 63.3% of tertiary education funding (before transfers) come from public sources, compared to OECD averages of 85.6% and 71.9%, respectively.
Although expenditure per student from primary to tertiary levels increased on average across OECD countries between 2015 and 2022 in real terms (from USD 11 955 to USD 13 210), government spending on education declined in relative terms from 10.9% of public budgets to 10.1%. This suggests the relative priority given to education in overall public spending has fallen across the OECD. In Bulgaria, expenditure per student increased from USD 5 060 to USD 7 558, while the share devoted to education increased from 7.3% of public budgets to 8.4% over this period.
At pre-primary level, government expenditure in Bulgaria increased substantially by 31.8% between 2015 and 2022. This is despite a decrease of 9.9% in the number of children enrolled. As a result, government expenditure per child has increased, by 46.2%, compared to an average increase of 24% across the OECD since 2015.
Many countries are experiencing teacher shortages, reflected not just in the number of unfilled teaching positions, but also in other indicators such as the share of non-fully qualified teachers in the teaching workforce. In the 14 countries and economies with data available, 1.6% of teaching positions are unfilled on average, and 4.9% of teachers are not fully qualified. In Bulgaria, the share of unfilled teaching positions is 0.4%, and the share of non-fully qualified teachers is 3.7%. However, cross-country comparisons of these data should be made with even greater caution than in other areas, as teacher recruitment processes vary significantly, ranging from centralised systems with competitive national exams to fully decentralised hiring at the school level, making comparisons of vacancy levels difficult.
High teacher turnover can place additional pressure on recruitment, while very low turnover may limit the renewal of the teaching workforce. In most countries with available data, between 1% and 3% of teachers retire each year. However, the share of teachers leaving the profession for reasons other than retirement varies more widely, ranging from almost none in some countries to nearly 10% in others. Bulgaria is among the countries with high turnover, with no further breakdown between retirements and resignations available (Figure 4).

Attracting second-career teachers can help alleviate teacher shortages while bringing individuals with a broader range of experience into the profession. To support this, 16 out of 28 countries with available data (including Bulgaria) offer dedicated alternative pathways into teaching for individuals changing careers.
The amount of compulsory instruction time affects teacher salary costs as it influences the number of teachers needed, combined with other factors such as class size and teaching time of teachers. In Bulgaria, students receive 507 hours of compulsory instruction per year in primary education and 740 hours in lower secondary education. This is below the OECD average of 804 hours in primary and 909 hours in lower secondary education.
School holidays in primary education last 15.8 weeks per year in Bulgaria (all breaks combined), compared to 13.5 weeks across the OECD.
In Bulgaria, 43% of instruction time in primary education is allocated to mathematics and reading, writing and literature, falling to 32% in lower secondary education. In comparison, the OECD average is for 41% of instruction time in primary education and 27% in lower secondary education to be devoted to these core subjects.
