The opinions of English teachers on the problems encountered in English teaching in the schools in Karabük Province were examined in this study, by taking a variety of variables into consideration. There are 231 English teachers in state schools in Karabük. A total of 67 English teachers serving in the primary schools, secondary schools and high schools in the central districts of Karabük Province-Turkey in the 2018-2019 school year participated voluntarily in the study, in which the Scale for Challenges Encountered by English Teachers Regarding Their Field, developed previously was translated into English and used. According to the results of the analysis, it can be said that while English teachers do not struggle with difficulties regarding collaboration with families, institutions, organisations and people in immediate and distant vicinities for the most part, they do struggle with difficulties in terms of making plans that are compatible with English teaching programmes. It was found that there are no significant differences in the opinions of English teachers regarding the challenges encountered in English teaching according to the variables of age, level of education, marital status, term of office, gender and school type. In light of all these assessments, it is thought that the identification and resolution of problems by determining and evaluating the perceptions of English teachers regarding the challenges encountered in English teaching will provide contributions to studies directed towards ameliorating and improving the quality of schools and education.
