Germany scored higher than the OECD average in science in PISA 2015, with a mean score of 509 points, compared to the OECD average of 493 points. Performance in science remained stable across PISA cycles, with an average score change of -1.7 score points, while reading performance has increased and mathematics performance has stayed the same. Socio-economic status had higher-than-average impact on science performance in PISA 2015, explaining 15.8% of the variance in performance (OECD average: 12.9%). The impact of ESCS on performance in science has not changed since 2006. Gender differences in science performance were higher than the OECD average, with a difference between boys and girls of 10 points, compared to the average difference across the OECD of 4 points. Immigrant students make up 16.9% of the student population of 15-year-olds in Germany, a higher proportion than the OECD average of 12.5%. Performance differences between immigrant and non-immigrant students are higher than the OECD average. Immigrants scored on average 50 score points lower than non-immigrants in science in PISA 2015, compared to the OECD average of 31 score points.
Enrolment of 3-year-olds in ECEC was higher than the OECD average in 2015, at 93.3% (OECD average: 77.8%). ECEC is organised as an integrated system for children from birth to school entrance. Since 2005, the supply of ECEC has strongly expanded for children under age 3, and attendance increasingly starts at an earlier age. In addition to ECEC services, some Länder also run preschool classes that children can attend alternatively at age 5. ECEC programmes are considered education-only programmes and are delivered by qualified ECEC teachers according to Länder curricula. Children who have reached compulsory school age but have not yet attained an adequate level of development to start school may take part in preschool educational programmes (Schulkindergarten, Vorklasse, Grundschulförderklasse). Compulsory education in Germany begins at age 6 and ends at age 18, longer than the typical duration across the OECD. Students are first tracked into different educational pathways at age 10, which is earlier than the OECD average of age 14. General upper secondary education (gymnasiale Oberstufe) is offered by academic high schools (Gymnasien) and comprehensive high schools (Gesamtschulen). Students can also choose a vocational track, which is divided into six occupational areas. The upper secondary general school leaving certificate (Abitur) constitutes a general higher education entrance qualification permitting the graduate to study any subject at any higher education institution. It is obtained after 12 or 13 years of education. A higher education entrance qualification is required for graduates from general and vocational upper secondary education who wish to continue. Students from the dual system (first cycle) and specialised vocational schools must obtain an occupational qualification before continuing to specialised vocational high schools (Berufsoberschulen), the dual system (second cycle), or health and social sector programmes).
VET is provided at upper secondary and post-secondary non-tertiary levels, and dual programmes are offered in over 300 trades, with an exit exam for the dual system that does not count school performance. Although very few VET graduates continue to tertiary education, there are short and long programmes they can attend in trade and technical schools. In the OECD Survey of Adult Skills in 2012 and 2015, adult literacy scores in Germany were higher than the OECD average, at 270 points, compared to the OECD average of 268 points. The proportion of the population aged 25-64 with lower secondary education as the highest level of attainment in Germany is relatively low, with an attainment rate of 10.1% in 2016, compared to the OECD average of 14.3%. NEET rates (the proportion of those aged 18-24 that are neither employed nor in education or training) are lower than the OECD average, at 10%, compared to the OECD average of 15.3%. The percentage of the population aged 25-34 with a tertiary-level qualification is lower than the OECD average, at 30.5% in 2016, compared to the OECD average of 43.1%. Employment rates for 25-34 year-olds with tertiary education are also relatively high. In 2016, 87% were employed, while the OECD average rate was 82.9%.
