This mixed-method study explores Saudi EFL teachers’ perspectives on students’ writing competencies and their concerns regarding the writing challenges, particularly in relation to EFL teachers, learners, and textbooks. The study sample consisted of 139 female EFL teachers working in Saudi Arabia. Data was gathered using a questionnaire composed of three sections: demographic information, 15 close-ended items, and three open-ended questions. The findings revealed that Saudi students’ writing skills are poor and fall below expectations. The results mainly showed their lack of vocabulary, grammar, spelling, punctuation, capitalization, transition words, legible handwriting, logical paragraph arrangement, concept flow, and genuine and supportive examples. The first open-ended question results revealed that these EFL teachers highlighted ten issues as negatively impacting the quality of students’ writing. The second open-ended question results showed eleven potential sources of these challenges related to learners. Finally, the results of the third open-ended question revealed six factors focusing on problems associated with textbooks potentially exerting a negative influence on the quality of students’ writing. The study concludes with some practical recommendations and suggestions for further research.
