TALIS 2008 Technical Report
The OECD’s new Teaching and Learning International Survey (TALIS) has been designed to provide data and analyses on the conditions needed for effective teaching and learning in schools. As the first international survey with this focus, it seeks to fill important information gaps that have been identified at the national and international levels of education systems.
This TALIS Technical Report describes the development of the TALIS instruments and methods used in sampling, data collection, scaling and data analysis phases of the first round of the survey. It also explains the rigorous quality control programme that operated during the survey process, which included numerous partners and external experts from around the world.
The information in this report complements the first international report from TALIS, Creating Effective Teaching and Learning Environments: First Results from TALIS (OECD, 2009) and the User Guide for the TALIS International Database.

Estimation Weights, Participation Rates and Sampling Error
This chapter covers three important aspects of the quality of the TALIS outcomes: weighting of the data to produce estimates, participation rates and an estimation of the sampling error. It begins by detailing how each component of the final estimation weight is defined and how those components are assembled into the final estimation weight, before describing participation rates and how they were computed.
