136 THURSDAY 21 JULY1 Australian Council for Educaonal Research and University of Melbourne, Australia; 2 Westat and Universityof Maryland, United StatesOver the past 20 years cross-naonal comparisons of educaonal achievement of school students have beenincreasingly frequent, and the results are now well-publicized. These studies constute a unique blend ofsurvey sampling and psychometric methodologies. By taking advantage of the fact that individual student resultsare not required, but rather data on the distribuon of achievement across the student populaon, thesestudies are able to provide rich detail while only requiring limited student me and moderate size samples ofschools and students.3.18.2 Preparing for the First Cycle of the Programme of Internaonal Assessment of Adult Competency(PIAAC)L. Mohadjer 11 Westat, United StatesAn extensive amount of research has been conducted and results have shown that there is a strong relaonshipbetween adult competency levels and economic success and social advancement of both individuals andcountries. Thus it comes as no surprise that European governments are increasingly interested in understandingthe level and distribuon of competency levels in their populaons and how they compare with othercountries in Europe or around the world.3.18.3 The Naonal Educaonal Panel Study in Germany: Purpose, Design and ChallengesJ. von Maurice 2 , V. Stocké 1 , H. Blossfeld 21 University of Bamberg, Germany; 2 Naonal Educaonal Panel Study (NEPS), GermanyEducaon is a key factor in modern sociees for individual life chances as well as for economic growth. Thereforethere is a high demand for high-quality data and in parcular for panel data in the area of educaonalresearch. Consequently the Naonal Educaonal Panel Study (NEPS) has been established in Germany. Paneldata have methodological advantages and allows to describe educaonal trajectories over the live course andto test different theorecal approaches about educaonal success and competence development. The NEPSdisnguishes eight stages in the live course that are integrated by five theorecal perspecves...3.18.4 Two-stage indirect sampling of Kindergarten children in the Naonal Educaonal Panel Study (NEPS)S. Koch 11 Naonal Educaonal Panel Study (NEPS), GermanyIn general sampling is based on a complete list. Complete lists of informaon concerning all units of the targetpopulaon enable using sampling strategies and geng – depending on the quality of list and strategy– unbiased esmators for parameters of the target populaon. Without a sampling frame direct sampling isnot possible. In this situaon Lavallée (2007) suggests to use an indirect sampling approach. If there existsa populaon with an available sampling frame and this populaon is connected to the target populaon ina uniquely defined manner, indirect sampling allows provision of a random sample of the target populaonand of weights perming an unbiased esmaon of populaon parameters. The connecon between bothpopulaons can be described by an indicator variable...3.19 Naonal minories in (inter)naonal surveys: Bias, Precision and data qualityTo be held on July 21, 2011 from: 11:00 to 12:30, in room 413.Coordinated by:
