In the present era, one of the most crucial aspects of foreign language education is the development of communicative competence. It enables us to understand and use language correctly, suitably, and well, regardless of our communicative, social, or cultural situation. This book offers an insight into the phenomenon and presents a qualitative inquiry conducted on 4th grade children in Slovakian primary schools, where English is taught as a foreign language. The aim of the study is to explore, understand, and describe communicative competence from a theoretical viewpoint and progress this knowledge into the reality of formal in-school education. A collection of three research methods investigate how communicative competence is regarded, developed, and understood and whether all of its components are perceived as equally important in the education process.
