The United Kingdom 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 -1.5 score points, while performance in reading and mathematics has stayed the same. Socio-economic status had lower-than-average impact on science performance in PISA 2015, explaining 10.5% of the variance in performance (OECD average: 12.9%). The impact of ESCS on performance in science has not changed since 2006. There was no significant gender difference in science performance in PISA 2015. Immigrant students make up 16.7% of the student population of 15-year-olds in the United Kingdom, a higher proportion than the OECD average of 12.5%. Performance differences between immigrant and non-immigrant students are lower than the OECD average. Immigrants scored on average 18 score points lower than non-immigrants in science in PISA 2015, compared to the OECD average of 31 score points.
At age 3, children typically attend some form of early education and childcare, for around one to two years before beginning the first year of primary school. Children in England and Wales also attend an initial “reception year” in primary school before proceeding to Year 1. There is no clear distinction between education-only and integrated programmes in England and no formal curriculum, although the Early Years Foundation Stage Profile does set guidelines. In England, there should be at least one qualified teacher in any nursery class in a school or nursery-school setting. The presence of a qualified teacher varies in private and voluntary provision. Compulsory education in England begins at age 5 and ends at age 18, longer than the typical duration across the OECD. Students are first tracked into different educational pathways at age 16, later than the OECD average of age 14. Participation in upper secondary education is compulsory until age 16 in Northern Ireland, Scotland and Wales, and until age 18 in England.
In most cases, general and vocational programmes in the United Kingdom are offered in upper secondary schools. Successful completers are awarded different types of upper secondary qualifications, including various types of vocational and academic qualifications. These qualifications aim to reflect what students need to know to succeed in further education or for employment. The proportion of the population aged 25-64 with lower secondary education as the highest level of attainment in the United Kingdom is higher than the OECD average, with an attainment rate of 17.8% 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 14.5% compared to the OECD average of 15.3%. The percentage of the population aged 25-34 with a tertiary-level qualification is among the highest in the OECD, at 52% in 2016, compared to the OECD average of 43.1%. Employment rates for 25-34 year-olds with tertiary education are higher than the OECD average. In 2016, 87% were employed, while the OECD average rate was 82.9%.
