This book addresses an important issue for the design of survey instruments, which is rarely taught in graduate programs beyond those specifically for statisticians. Item Response Theory is used to describe the application of mathematical models to data from questionnaires and tests as a basis for measuring abilities, attitudes, or other variables. It is used for statistical analysis and the development of assessments, often for high stakes tests such as the Graduate Record Examination. This volume includes examples of both good and bad write-ups for the methods sections of journal articles.Less

This chapter begins by highlighting the critical features of Curriculum-Based Measurement (CBM) that make it possible to use the measures in conjunction with current large-scale assessments. It acknowledges that, under the leadership of Stanley Deno, individuals who have worked with CBM over the past four decades are ready to take the measurement system to a new level, as they interact with other measurement systems from state departments of education. This next level would involve the use of more precise scaling, presumably using some form of Item Response Theory (IRT). Finally, the chapter proposes how CBM can provide critical information to help teachers make important decisions about student participation in large-scale testing programs.Less

Public procurement accounts for a significant portion of countries’ GDP and offers large potential for savings in times of austerity. To improve the effectiveness of their infrastructure investments many countries have taken various steps to modernise public procurement processes. However, due to the huge range of available options, governments are increasingly faced with the challenge to reconcile multiple objectives and to select the ones with the largest potential for benefits. This chapter explores how successfully countries have managed to introduce innovative strategies and tools to modernize their public procurement processes. Using Item Response Theory for estimating countries’ policy capacity and the difficulty of its implementation, a set of indicators explores five key areas that are recommended to boost the efficiency of public infrastructure procurement. The analysis demonstrates that countries vary in their capacities to modernize procurement processes and only a few governments manage to perform well across the five areas.Less
