Different instruments analyze university students’ and pre-service teachers’ attitudes towards statistics, but few studies investigate in-service teachers’ attitudes. The attitude scale towards statistics (Estrada, 2002) has been used in some countries with in-service teachers and has presented good psychometric values. This study carried out a comparative analysis of global and by-items results of this attitudes scale applied to primary school teachers in Peru, Spain, Portugal, and Brazil derived from prior research. Results suggest that the scale is adequate for the context of Latin America, and differences in the attitudes among the countries were found. These differences are analyzed considering the formative and curricular context of each country. Following this, recommendations are made for the continuous training of teachers.
