This regional dossier aims to provide a concise, description and basic statistics about minority language education in a specific region of Europe. Latgalian is a Baltic regional language originating in the region of Latgale (Latgalian: Latgola) in Eastern Latvia. It is mostly spoken in Latgale, but also in families and small communities of people from Latgale living in other parts of Latvia. Every Regional Dossier begins with an introduction about the region in question, followed by six chapters that each deal with a specific level of the education system (e.g. primary education). Chapters 8 and 9 cover the main lines of research into education of the minority language under discussion, and the prospects for the minority language in general and in education in particular, respectively. Chapter 10 provides a summary of statistics. Lists of (legal) references and useful addresses regarding the minority language are given at the end of the dossier. [This Regional Dossier was originally prepared by Heiko F. Marten, Ilga Šuplinska, and Sanita Lazdina. This second version covers academic data for the 2020-2021 school year.]
