In the first part the analysis of statistical data concerning the number of foreign pupils in Polish schools (divided into provinces) was done from the school year 2001/2002 to 2013/2014. This part also consists of law regulations knowledge associated with the education of the “Culturally different” children in the other cultural and educational institutions in Poland. The second part consists of characteristics of the teachers’ and headmasters’ competence and the difficulties they encounter in their work. In this part has been cited partial results of research based on qualitative interviews conducted by the author in 2011–2014 with teachers who teach foreign children in schools in Warsaw. It was also given an example of “good practice” schools that have developed their own methods of working with the immigrant students.
