Education at a Glance 2025: Slovak Republic
Table of contents
This country note provides an overview of the key characteristics of the education system in the Slovak Republic 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.
Educational inequalities persist across generations. In all countries with available data, young adults (25-34 year-olds) are significantly more likely to attain a tertiary qualification if their parents have also done so. In the Slovak Republic, 65% of 25-34 year-olds with at least one tertiary-educated parent have also attained a tertiary qualification, compared to only 3% among those whose parents did not complete upper secondary education. This tertiary-attainment gap of 62 percentage points is one of the largest among OECD countries gap of 44 percentage points (Figure 1).

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 the Slovak Republic, where the share fell from 9% to 7% 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 the Slovak Republic (albeit at a higher level): 39.9% of young adults without an upper secondary qualification are unemployed, compared to 6.1% of those with upper secondary or post-secondary non-tertiary attainment and 2.8% of those with tertiary attainment (Figure 2).

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 the Slovak Republic, 29% of 25-34 year-olds hold a master’s or equivalent degree, which is well above the OECD average of 16%. This represents a decrease since 2019, when the share was 31%.
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 the Slovak Republic, the wage gap between workers with and without upper secondary attainment is similar to the OECD average, at 16%. The gap between those with upper secondary and tertiary attainment is identical to the OECD average, at 54%.
In most OECD countries, a significant share of adults have low levels of literacy proficiency, defined as at or below Level 1 (on a scale of 0-5) in the OECD Survey of Adult Skills, a product of the OECD Programme for the International Assessment of Adult Competencies (PIAAC). Individuals at this level can only understand very short texts with minimal distracting information. In the Slovak Republic, 23% of 25-64 year-olds have literacy skills at or below Level 1, which is below the OECD average of 27%.
Educational attainment and skills are closely linked, although the strength of this relationship varies across countries. In the Slovak Republic, tertiary-educated adults score, on average, 18 points higher in literacy proficiency than those with upper secondary or post-secondary non-tertiary attainment in the Survey of Adult Skills. This gap is smaller than the OECD average difference of 34 points.
Average literacy scores fell between Cycle 1 (2012-15) and Cycle 2 (2023) of the Survey of Adult Skills1. On average across OECD countries, the fall among adults with tertiary attainment was 9 score points, smaller than the average drop of 19 score points among adults without upper secondary qualifications. In the Slovak Republic, average literacy scores for adults with tertiary attainment decreased by 25 points (from 295 to 271), while the score for adults without upper secondary attainment decreased by 18 points (from 237 to 220).
In the Slovak Republic, as in all OECD countries, adults with better literacy skills are more likely to participate in education and training. In 2023, 52% of adults (25-64 year-olds) with high literacy proficiency (i.e. at or above Level 4) in the Survey of Adult Skills participated in formal and/or non-formal education and training in the last year, compared to just 19% of those with proficiency at or below Level 1.
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. The Slovak Republic experienced a decline of 3% in the number of 0-4 year-olds, and is projected to see a decline of 18% 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 the Slovak Republic, the share is at the upper end of the OECD distribution in 2023, at 8.2%.
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 the Slovak Republic, the share is even higher at 91%.
Women make up the majority of first-time entrants to tertiary education in most OECD countries. In the Slovak Republic, they accounted for 53% of first-time entrants in 2023, down from 57% 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 the Slovak Republic, 20% of bachelor’s degree students graduate from a STEM field, 19% from business, administration and law, and 18% 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. The Slovak Republic was among the countries with a substantial increase, with the share rising from 8% to 15.2% (Figure 3).

There are significant disparities in how much governments spend each year in education across OECD, partner and accession countries. The Slovak Republic spends USD 9 056 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 4).
In equivalent USD converted using PPPs, expenditure on educational institutions

2. Primary includes pre-primary education.
3. Includes payments by households outside educational institutions.
For data, see OECD (2025) Education at a Glance 2025: OECD Indicators, https://doi.org/10.1787/1c0d9c79-en, Table C1.1 and Table C1.2.
As in most other countries, government expenditure in the Slovak Republic is higher at tertiary level, including research and development (R&D), than at primary to post-secondary non-tertiary levels. Government expenditure in the Slovak Republic amounts to USD 15 241 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 the Slovak Republic, education investment in primary to tertiary education stands at 4.2% 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 the Slovak Republic, governments provide 89.1% of total funding for primary, secondary, and post-secondary non-tertiary education (before transfers to the private sector), which is below the OECD average of 90.1%. At the pre-primary and tertiary levels, private funding often plays a larger role. In the Slovak Republic, 89.9% of pre-primary education funding (after transfers) and 78.6% 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 the Slovak Republic, expenditure per student increased from USD 9 216 to USD 10 326, while the share devoted to education increased from 9.1% of public budgets to 9.3% over this period.
At pre-primary level, government expenditure in the Slovak Republic increased substantially by 55.1% between 2015 and 2022. This is partly due to an increase of 13.9% in the number of children enrolled. As a result, government expenditure per child has increased, by 36.2%, compared to an average increase of 24% across the OECD since 2015.
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. The Slovak Republic is among the countries with moderate turnover, with 2.7% of teachers retiring and 3.7% resigning each year (Figure 5).

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 the Slovak Republic) offer dedicated alternative pathways into teaching for individuals changing careers.
Competitive salaries can make the teaching profession more attractive, particularly since teachers in many countries earn less than other tertiary-educated workers. In the Slovak Republic, the actual salaries of primary teachers are 26% lower than those of tertiary-educated, full-time, full year workers, compared to an average of 17% lower across the OECD. However, increasing teacher salaries can be financially challenging, as staff costs make up the largest share of education expenditure (Figure 6).
Ratio of salaries to the earnings of full-time, full-year workers aged 25-64
Note: Data refer to the ratio of annual average salaries (including bonuses and allowances) of teachers and school heads in public institutions relative to the earnings of workers with similar educational attainment (weighted average) and to the earnings of full-time, full-year workers with tertiary education. Earnings of workers with similar educational attainment to teachers are weighted by the distribution of teachers (or school heads) by qualification level (see Tables X2.10 and X2.11). As values close to one may be difficult to identify in the figure, please refer to the source table.
1. Data on earnings for full-time, full-year workers with tertiary education refer to the whole country.
2. Year of reference for salaries of teachers differs from 2024.
For data, see OECD (2025) Education at a Glance 2025: OECD Indicators, https://doi.org/10.1787/1c0d9c79-en, Table D3.2.
Since 2015, actual average salaries of primary teachers have increased in real terms by 14.6% on average across the OECD. In the Slovak Republic, they increased by 30.7% in 2024.
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 the Slovak Republic, students receive 680 hours of compulsory instruction per year in primary education and 828 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 13.2 weeks per year in the Slovak Republic (all breaks combined), compared to 13.5 weeks across the OECD.
In the Slovak Republic, 49% of instruction time in primary education is allocated to mathematics and reading, writing and literature, falling to 31% 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.
Across the OECD, the average class size at primary level has not changed since 2013, at 20.6 students. In the Slovak Republic, the average class size in primary education in 2023 was 18.5 students, up by 1 since 2013.
At tertiary level, the average ratio of students to academic staff varies across different types of institutions. In many countries, institutions with a strong research focus, defined as those with more than three doctoral graduates per 100 graduates, tend to have lower student staff ratios than those with a smaller share of doctoral graduates. This is also the case in the Slovak Republic, where institutions with greater research focus have an average of 8 students per academic staff member, compared to 14 students per academic staff member at institutions with a smaller share of doctoral graduates.
Countries use a range of admission systems to tertiary public education institutions. These vary as to whether admission is open or selective, and whether applications are submitted directly to institutions or to a central body. In the Slovak Republic, admission is open for some programmes and selective for others. Applicants submit their applications directly to institutions.
In most countries, academic staff salaries vary significantly by seniority. Staff in junior academic positions often earn well below the average salary for tertiary-educated, full-time, full year workers, while staff in senior positions — such as full professors — typically earn well above this average. In the Slovak Republic, junior academic staff earn 32% less than workers with at least a bachelor’s or equivalent degree, while senior academic staff earn 33% more.
