This study aimed to investigate the challenges and opportunities experienced by teachers in piloting the integrated curriculum in Lesotho. Moreover, this research was underpinned by a Constructivist paradigm which concedes that peoples’ views of the world are influenced by their experiences. The qualitative case study research design was employed and data were generated through the semi-structured interviews. In particular, purposive sampling technique was deployed to obtain sufficient and useful data. For this reason, three teachers with ten years teaching experience were selected from three departments in a chosen school. The departments included; Commercial studies, Science and Mathematics as well as Languages respectively. Overall, findings from this study affirm that constraints experienced while piloting the integrated curriculum outweigh the prospects. The opportunities raised included the following; development of creative skills and nurturing of the students’ talent while the challenges highlighted were; content overload, lack of CPD, absence of monitoring and supervision among others. Therefore, the implications of these findings are that a successful implementation of the reformed curriculum is under threat. In order to reprimand this threat, provision of regular workshops, monitoring and evaluation of the CPD programmes, reliable internet coverage, free data bundles for both teachers and students, as well as frequent follow ups by curriculum developers may address the issues of concern hence improve the quality of education as intended by the Lesotho Curriculum and Assessment Policy of 2009.
