Norway scored higher than the OECD average in science in PISA 2015, with a mean score of 498 points, compared to the OECD average of 493 points. Performance in science remained stable across PISA cycles, with an average score change of 3.1 score points, while performance in reading and mathematics has also stayed the same. Socio-economic status had one of the lowest impacts in the OECD on science performance in PISA 2015, explaining 8.2% 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 12% of the student population of 15-year-olds in Norway, close to the OECD average of 12.5%. Performance differences between immigrant and non-immigrant students are slightly higher than the OECD average. Immigrant students scored on average 35 score points lower than native students in science in PISA 2015, compared to the OECD average of 31 points.
Education and care are seen as integrated in the national pedagogical framework in Norway. Enrolment of 3-year-olds in ECEC was among the highest in the OECD in 2015, at 95.5% (OECD average: 77.8%). Kindergarten (Barnehage) covers the age span of 0-5 years, and children typically attend beginning at age 1, when they become entitled to a place. Kindergartens have a formal curriculum framework in place that is delivered by qualified teachers and assistants (Framework Plan for the Content and Tasks of Kindergarten). Compulsory education in Norway begins at age 6 and ends at age 16, similar to 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. A comprehensive upper secondary system combines academic education and vocational training, offering students three general academic programmes and nine vocational programmes. After two years of vocational studies, or after completing the four-year vocational studies programme, students can enter university if they complete a supplementary year.
The majority of students enter vocational upper secondary education (53% in 2011, compared to the OECD average of 44%), but completion rates are below the OECD average. In the OECD Survey of Adult Skills in 2012 and 2015, adult literacy scores in Norway were higher than the OECD average, at 278 points, compared to the OECD average of 268 points. gap in literacy skills between older adults (age 55-65) and younger adults (age 25-34) was higher than the OECD average. The proportion of the population aged 25-64 with lower secondary education as the highest level of attainment in Norway is higher than the OECD average, with an attainment rate of 17.1% 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 9.7% compared to the OECD average of 15.3%. The percentage of the population aged 25-34 with a tertiary-level qualification is higher than the OECD average, at 48.6% 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, 86.6% were employed, while the OECD average rate was 82.9%.
