Portugal scored higher than the OECD average in science in PISA 2015, with a mean score of 501 points, compared to the OECD average of 493 points. Performance in science has improved substantially across PISA cycles, with an average score change of 7.6 score points, and performance in reading and mathematics has also increased. Socio-economic status had a higher-than-average impact on science performance in PISA 2015, explaining 14.9% 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 in Portugal, 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 7.3% of the student population of 15-year-olds in Portugal, a lower 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 16 score points lower than non-immigrants in science in PISA 2015, compared to the OECD average of 31 score points.
Children can begin pre-primary education (Educação pré-escolar) between age 3 and age 5, and around 80% of children typically enrol at age 3. Pre-primary education lasts three years and follows the national Curriculum Guidelines for Pre-school Education. Compulsory education begins at age 6 and ends at age 18 or upon completion of upper secondary education, longer than the typical duration across the OECD. Students are first tracked into different educational pathways typically at age 15, later than the OECD average of age 14. Upper secondary education lasts three years and offers a range of programmes, including science-humanities courses, technological courses, specialist artistic courses and a large choice of dual-certification vocational courses.
VET in upper secondary education is available for those who have completed at least nine years of schooling or equivalent training. VET programmes in upper secondary education play an important role in Portugal and are primarily school-based (non-dual) programmes offered in comprehensive public schools or specialised professional schools. The Vocational Training Centre network, governed by a national agency responsible for employment policies, provides apprenticeship programmes (with both theoretical and practical training) to assist young people under age 24 to find employment or continue their education. Transition pathways from VET programmes to tertiary education are available, although entrance into academic programmes is subject to the same requirements as for those enrolled in general programmes.
The proportion of the population aged 25-64 in Portugal with lower secondary education as the highest level of attainment is higher than the OECD average, with an attainment rate of 20.4% in 2016, compared to the OECD average of 14.3%. NEET rates (the proportion of those aged 18-24 that are not employed or in further education or training) are higher than the OECD average, at 18.2%, compared to the OECD average of 15.3%. The share of the population aged 25-34 with a tertiary-level qualification is relatively low, at 35% in 2016, compared to the OECD average of 43.1%. Employment rates for 25-34 year-olds with tertiary education are similar to the OECD average. In 2016, 82.3% were employed, while the OECD average rate was 82.9%.
