This chapter draws from the analyses presented in the previous chapters of this report as well as the TALIS 2013 Results: An International Perspective on Teaching and Learning (OECD, 2014) report to provide comparisons between primary, lower secondary and upper secondary school teachers. In doing so, it examines teachers’ characteristics, profiles of the schools they work in, classroom characteristics, professional development, teaching practices and feelings and attitudes toward their profession. The comparisons are made across the countries with data available from at least two of these educational levels.
