This article presents information on 2 international educational effectiveness studies, one completed and the other ongoing. The 2nd study is, to a large degree, a reaction to a methodological problem encountered in the 1st study, the lack of an internationally valid instrument measuring teacher effectiveness. This article presents 4 reasons for conducting the 2nd study (International System for Teacher Observation and Feedback (ISTOF)) and then details the overall work plan for ISTOF-I (2004 - 2006) and ISTOF-II (2006 - 2007). The sample of 20 fully participating country teams in ISTOF is very diverse with representatives from nearly all geographic areas of the world (North and South America, Europe, Africa, Asia), many of which have never participated in teacher or school effectiveness research. This article summarizes progress made on the development of the ISTOF protocol, including the generation of components and indicators of teacher effectiveness. In many ways, the study is already a success, due to the diversity of the participating countries and their generation of major parts of the protocol during ISTOF-I. Nevertheless, this article concludes with a discussion of some of the major challenges that the research team will face as it begins ISTOF-II.

An outline is given of the context in which The International School Effectiveness Research Project (ISERP) was designed and it is argued that the deficiencies of existing studies and the increased internationalization of education makes the more rigorous approach of ISERP essential. A number of methodological lessons from the study are given, concerning the need for cohort studies, for observational data, for social outcomes data, for mixed methods, and for multiple indicators. The substantive lessons of the study for a strong technology of education, for a taken for granted in educational discussions within cultures, for societal support of education within cultures, and for a radical intellectual orientation are given.

Private supplementary tutoring has long been a major phenomenon in parts of East Asia, including Japan, Hong Kong, South Korea and Taiwan. In recent times it has grown dramatically in other parts of Asia and in Africa, Europe and North America. The factors underlying the growth of private tutoring vary, but in all settings it has major implications for learning and livelihood. Families with the necessary resources are able to secure not only greater quantities but also better qualities of private tutoring. Children receiving such tutoring are then able to perform better in school, and in the long run to improve their lifetime earnings. By contrast, children of low‐income families who do not receive such benefits may not be able to keep up with their peers and may drop out of school at an earlier age. Tutoring also of course has a direct impact on the livelihoods of the tutors, providing employment and incomes for a range of professionals and amateurs of different age groups. The dynamics of inter‐relationships are complex, and vary from one setting to another. This paper argues that private supplementary tutoring deserves much more attention from policy makers and researchers.
