In this policy paper we discussed a broad range of topics covering student access to computers at home and school, different uses of computers for learning and the impact of ICT use on different groups of students. Introducing computers into schools generates both new opportunities and...

Does decentralization enhance service delivery and poverty reduction? Drawing on cutting edge research, expert contributors address this fundamental question facing policy-makers in developing as well as advanced countries. This timely book builds upon insights on the recent developments in the...

Poland is one of the few European countries that achieved strong improvement of student performance over the last decade. According to the OECD PISA results Poland moved from below to above the OECD average and now is close to top-performing countries. The score improvements are a consequence of...

This paper examines how including latent variables can benefit propensity score matching. Latent variables can be estimated from the observed manifest variables and used in matching. This paper demonstrates the benefits of such an approach by comparing it with a method where the manifest...

In order to stabilise and improve their income situation, rural households are strongly encouraged to diversify their activities both within and outside the agricultural sector. Often, however, this advice is only moderately pursued. This paper addresses issues of rural household income...

The predictive power of the PISA test items for future student success is examined based on data from the Longitudinal Surveys of Australian Youth (LSAY) for the PISA 2003 cohort. This working paper analyses how students’ responses to mathematics and problem-solving items in PISA 2003 are...

This paper discusses a method to compare progress in reading achievement from primary to secondary school across countries. The method is similar to value-added models that take into account intake levels when comparing student progress in different schools. Value-added models are preferred over...

In this paper we analyze class size effects in the case of primary schools in Poland. We use two empirical strategies to avoid endogeneity bias. First, we use average class size in a grade as an instrumental variable for actual class size. This allows us to control for within school selection of...

This paper examines how including latent variables can benefit propensity score matching. A researcher can estimate, based on theoretical presumptions, the latent variable from the observed manifest variables and can use this estimate in propensity score matching. This paper demonstrates the...
