Abstract. High volume and special structure International Large-Scale Assessment data such as PISA (Programme for International Student Assessment), TIMSS (Trends in International Mathematics and Science Study), and others are of interest to social scientists around the world. Such data can be analysed using commercial software such as SPSS, SAS, Mplus, etc. However, the use of open-source R software for statistical calculations has recently increased in popularity. To encourage the social sciences to use open source R software, we overview the possibilities of five packages for statistical analysis of International Large-Scale Assessment data: BIFIEsurvey, EdSurvey, intsvy, RALSA, and svyPVpack. We test and compare the packages using PISA and TIMSS data. We conclude that each package has its advantages and disadvantages. To conduct a comprehensive data analysis of International Large-Scale Assessment surveys one might require to use more than one package.

Abstract. We focus on two types of centralised national examinations (the 10th grade tests and Matura examination) that are being carried out in Lithuania for two decades. The aim of the paper is to analyse assessments of mathematics for the entire Lithuanian secondary school population that have no sampling errors while considering the factors of location, school ownership and gender as important indicators when judging about educational effectiveness in terms of quality and equity. We analyse the results of the 10th grade tests for the 2011–2015 period and the results of the same cohorts participating in the Matura examination. We observe that the distribution of the assessments of both exams is asymmetric with a positive skew. The median often is below the middle of the grade scale indicating poor performance or mismatch between knowledge and examination tasks. There are limited differences in assessments with respect to gender and school location, although we detect a tendency to have better mathematics achievement in private schools. The conclusions drawn from national assessment data is somewhat different from international data thus one cannot neglect national information for the development of educational policy. The variables analysed in the analysis has limited predictive power for achievements in mathematics and further analysis is called-for.

Abstract. The aim is to analyse assessments of Lithuanian language and literature for the entire secondary school student population focusing on gender comparison, and development of models for the prediction of achievements. We use the results of the 10th grade test for the period 2011–2015 and the same cohorts in the Matura exam. Gender differences are observed in analysed national centralized assessments. The distribution of the 10th grade test achievements resembles the bell-shaped curve, whereas the Matura – do not.

Santrauka. Straipsnyje nagrinėjama švietimo tikslų daugialypiškumo ir jų redukavimo į išmatuojamus rodiklius problema. Aptariami klausimai, ar vis labiau įsivyraujanti orientacija vien tik į mokinių mokymosi pasiekimus, dažniausiai apsiribojant PISA tyrimo duomenimis, yra kintamo globalaus požiūrio į švietimo daugialypiškumą išraiška; kokia švietimo paskirties samprata vyrauja šiandieniame pasaulyje; ar galima kalbėti apie universalius globalaus švietimo tikslus; kokią ateities švietimo viziją projektuoja didžiausią įtaką švietimo politikai darančios tarptautinės organizacijos; kaip švietimo tikslų redukavimas į rezultatų rodiklius atsispindi Lietuvos švietimo politikoje.

Abstract. This article deals with the problem of the multiplicity of educational goals and their reduction into measurable indicators. The paper debates whether an increasingly predominant student performance-centered approach, which is mainly limited to PISA findings, is a manifestation of a changing global educational paradigm; what concept of educational purposes prevails in today’s world; whether the global universal goals of education can be considered; what vision for the future of education is being projected by international organizations, which strongly influence education policy; how the reduction of educational goals into performance indicators is reflected in Lithuanian education policy.

Abstract. This paper examines the links between student learning and school leadership focusing on Lithuania in comparative perspective. Different aspects of school leadership areas are being outlined, but after a more thorough analysis of the educational effectiveness perspective, it seems that the direct link between principal and student achievement is not that clear. In order to explain this, we further analysed the role which school autonomy plays in effective leadership and found that different countries chose different levels of power distribution. After revealing diversity in meta-analyses and reviews about the existing effect sizes of school decentralization we looked into different tasks on which school heads spend their time, and noticed that instructional leadership is most effective in adding value to student achievement. What exactly counts as instructional leadership is debated and may change depending on context. The presumption that leadership and school effectiveness are related, could be valid only if school accountability and autonomy particularities are taken into account, therefore the reforms in selection, recruitment and training of school heads could be expected to drive effectiveness of education systems only as far as the right balance of the three (accountability, autonomy, leadership) are found.
