Project work is used in several educational settings, including foreign and second language teaching contexts. In the Moroccan English as a foreign language (EFL) classroom, the Moroccan Ministry of Education recommended implementing project work, and it is a common component of the Moroccan textbooks of English. Yet, there is a scarcity of studies conducted on the use of project work in Moroccan EFL classrooms. The main aim of the study is to investigate students' and teachers' attitudes towards project work. The study addresses the question about students' and teachers' attitudes towards project work and the factors behind those attitudes. It was conducted with sixty students and eight teachers belonging to two different high schools (Moulay Rachid and Abbas Sebti high schools) in Tangier. To collect data, the researcher made use of two data collection methods, namely the questionnaire and the interview. The results of the study showed that both students and teachers had positive attitudes towards project work. The results also revealed that not all teachers follow the steps of using project work. Based on the results, it was clear that the lack of technology is one of the most severe challenges that hamper the use of project work. The findings of this study could form the basis for further research and contribute to improving the learning and teaching situation in Moroccan high schools.
