In PISA 2015, Chile scored among the lowest in the OECD in science, with a mean score of 446 points, compared to the OECD average of 493 points. Performance in science remained stable across PISA cycles, with an average score change of 2.4 score points, while reading performance has increased and mathematics performance has stayed the same. Socio-economic social and cultural status had one of the largest impacts in the OECD on science performance in PISA 2015, explaining 16.9% of the variance in performance (OECD average: 12.9%). However, equity in science performance has increased significantly since PISA 2006. Gender differences in science performance were among the highest in the OECD, with a difference between boys and girls of 15 points, compared to the average difference across the OECD of 4 points. Immigrant students make up 2.1% of the student population of 15-year-olds in Chile, 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 23 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 lower than the OECD average in 2015 (at 55.6%, compared to the OECD average of 77.8%. However, at age 4, Chile’s enrolment rate is 86%, close to the OECD average of 87%. Pre-primary education (Educación parvularia) is organised by levels, with day care and a lower middle level (sala cuna y nivel medio menor) for children age 0-2, and upper middle and lower and upper transition levels (nivel medio mayor, nivel de transición 1 y nivel de transición 2) for children age 3-5. A national curriculum for early childhood education is in place for children age 0-5. Also, education-only and integrated education and care pre-primary programmes exist nationally. Both offer formal curricula that are delivered by qualified teachers. Compulsory education in Chile 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 16, later than the OECD average of age 14. Upper secondary education is a four‑year programme with a choice of three streams. Students can choose between general, artistic and technical education. Virtually all upper secondary graduates who expect to continue education take an entry exam (Prueba de Selección Universitaria, PSU). This exam, introduced in 2004, is an important gatekeeper into higher education, as the scores determine access to tertiary academic (type-A) programmes. Upon completion of each education stream, students receive a high school certificate, which allows them to advance to university, a professional institute (Instituto Profesional, IP), or a technical training centre (Centro de Formación Técnica, CFT).
VET is included in the technical professional education stream of the formal education system, where it is taught in technical and professional schools. After 12 years of compulsory education, students receive a secondary school leaving certificate (licencia de enseñanza media) and can obtain the title of middle-level technician if they complete workplace training (práctica profesional). Tertiary-level technical and vocational education and training (TVET) includes two-year programmes offered in CFTs, and four-year programmes in IPs, where students can develop high-level technical skills in fields like technology, agriculture or commerce. In the OECD Survey of Adult Skills in 2012 and 2015, adult literacy scores in Chile were relatively low, at 220 points, compared to the OECD average of 268 points. The proportion of the population age 25-64 with lower secondary education as the highest level of attainment in Chile is among the highest in the OECD, with an attainment rate of 22.2% in 2016, compared to the OECD average of 14.3%. NEET rates (those aged 18-24 that are not employed or in education or training) are also higher than average, at 21.1% compared to the OECD average of 15.3%.
