This study aims to share English language practitioners' reflections on the adaptation of teaching methods and materials during the pre-validation period of the European Language Portfolio (ELP). In order to achieve this aim, a high school was selected as the scope of research, since it has started to adapt the English language teaching curriculum, syllabuses, instruction methods and assessment in line with the Common European Framework for the teaching of English as a foreign language for the last 4 years. A focus group of eight teachers was selected to collect data via semi-structured interviews. During the data collection procedure, the participants evaluated the process and procedures in terms of the related themes of SWOT analysis. The collected data was analyzed through coding and theme identification.
