"Education at a Glance: OECD Indicators" is the authoritative source for information on the state of education around the world. It provides data on the structure, finances and performance of education systems in the 35 OECD and a number of partner countries. With more than 100 charts and tables, Education at a Glance 2018 imparts key information on the output of educational institutions, the impact of learning across countries, and worldwide access, participation and progression in education. It also investigates the financial resources invested in education, as well as teachers, the learning environment and the organisation of schools. The 2018 edition presents a new focus on equity in education, investigating how progress through education and the associated learning and labour market outcomes are impacted by dimensions such as gender, the educational attainment of parents, immigrant background, and regional location. The publication introduces a chapter dedicated to Target 4.5 of Sustainable Development Goal 4 on equity in education, providing an assessment of where OECD and partner countries stand in providing equal access to quality education at all levels. Finally, new indicators are introduced on equity in entry to and graduation from tertiary education, and the levels of decision-making in education systems. New data are also available on the statutory and actual salaries of school heads, as well as trend data on expenditure on early childhood education and care and the enrolment of children in all registered early childhood education and care settings. More data are available on the OECD educational database. [For "Education at a Glance 2017: OECD Indicators," see ED580867.]
