Annex B provides the background questionnaires used in the PISA 2009 survey to obtain information about the participating schools, students and parents. There are different questionnaires for each group: The school questionnaire is administered to principals and covers the structure and organisation of the school; the student and teacher body; the school’s resources; the school’s instruction, curriculum and assessment; the school climate; the school’s policies and practices; and the characteristics of the principal or designate. The questionnaire for students addresses their educational career; family context and home resources; individual engagement in reading; instructional time, learning and assessment; classroom and school climate; access to and use of libraries; and students’ strategies in reading and understanding texts. Two optional questionnaires are administered to students: an educational career questionnaire covering the students’ educational histories and career aspirations; and a questionnaire about students’ access to information and communication technology and their use of and attitude towards computers. A third optional questionnaire for parents covers their children’s past reading engagement; their own reading engagement; home reading resources and support; parents’ background; their perception of and involvement in school; and school choice.
