The purpose of the study was to examine the Kuwaiti first grade teachers' perceptions of developmentally appropriate practices in teaching reading and writing. To achieve the research purpose, a questionnaire was developed and administrated to 167 first grade teachers. Results revealed that first grade teachers hold moderate agreement towards developmentally inappropriate practices in teaching reading and writing more than developmentally appropriate practices. Moreover, the results revealed no statistical significant difference regarding teachers' perceptions of teaching reading and writing due to gender and type of school, whereas there was a significant difference due to years of working experience. This study highlights the need to provide information to first grade teachers about the developmentally appropriate practices in teaching reading and writing.
