Early childhood education and care programmes (ECEC) have become more accessible in recent years, with high enrolment rates in both early childhood educational development and preprimary education. The educational results of students at the age of 15 may be partially explained by attendance at pre-primary education, which sharply decreases the likelihood of low performance in the Programme for International Student Assessment (PISA). Pre-primary education can play a strong role in promoting equality at an early age, particularly by targeting disadvantaged groups such as first- and second-generation immigrants. Assuring and monitoring the quality of programmes is key to guaranteeing that early childhood education and care has a positive impact on both equity and performance in education.
