"Education at a Glance" is the authoritative source for information on the state of education around the world. It provides key information on the output of educational institutions; the impact of learning across countries; the financial and human resources invested in education; access, participation and progression in education; and the learning environment and organisation of schools. The 2016 edition introduces a new indicator on the completion rate of tertiary students and another one on school leaders. It provides more trend data and analysis on diverse topics, such as: teachers' salaries; graduation rates; expenditure on education; enrolment rates; young adults who are neither employed nor in education or training; class size; and teaching hours. The publication examines gender imbalance in education and the profile of students who attend, and graduate from, vocational education. The report covers all 35 OECD countries and a number of partner countries (Argentina, Brazil, China, Colombia, Costa Rica, India, Indonesia, Lithuania, the Russian Federation, Saudi Arabia and South Africa). This edition includes more than 125 figures and 145 tables. The Excel™ spreadsheets used to create them are available via the StatLinks provided throughout the publication. More data is available in the "OECD Education Statistics" database. The following are appended: (1) Characteristics of Education Systems; (2) Reference Statistics; (3) Sources, Methods and Technical Notes; (4) Contributors to This Publication; and (5) Education Indicators in Focus.
