Professional learning community (PLC) has been a generally recognized model for promoting teacher development, including EFL teachers’ writing assessment literacy, intercultural teaching competence, digital literacy, and so on. However, research on whether the changes in beliefs of teachers engaging in a PLC affects their teaching competence is relatively scant. To fill this gap, the present study investigated the extent to which a PLC with intercultural components changed EFL teachers’ beliefs in intercultural teaching, which in turn affected their intercultural teaching competence. In doing so, adopting an exploratory sequential method, qualitative data from teachers and a questionnaire from students were collected and analyzed through NVIVO 12 and SPSS 26.0. The data analyses revealed significant changes in the EFL teachers’ knowledge construction, motivation inspired by peer interaction, and reflection on intercultural learning and teaching practices. These changes led to the transformations in their beliefs and practices concerning intercultural instruction, although individual orientations were observed in their pedagogical approaches. Furthermore, the study’s findings were supported by evidence of corresponding changes in students’ learning outcomes in the development of intercultural competence. The study highlights the significance of PLCs in enhancing EFL teachers’ intercultural teaching competence and their professional development.

In- service professional development activities seem to be of much significance to teachers who face challenges in teaching or teaching related issues such assessment and curriculum development. Despite the rich literature review of teachers' professional development, in-service professional development needs of EFL teachers have not been assessed yet. The present study aimed at developing and validating an in-service professional development needs scale for EFL teachers. In doing so, a mixed research method was used.  In the qualitative phase, the professional development needs were explored through interviewing with 20 EFL teachers who were selected through purposive sampling. In the quantitative phase, the professional development scale was submitted to 220 teachers. Data were analyzed through running exploratory factor analysis and Cronbach's alpha. Results showed that extracted professional development needs were reduced to four main areas: a) teaching, communication skills and assessment, b) educational psychology and technology, c) material development, and d) language and meta-language skills. The findings can be used by language schools and educational centers to provide EFL teachers with the most urgent professional development needs.
