This research paper endeavors to evaluate, assess and assert the expediency and efficacy of employing content and language integrated learning (CLIL) in teaching Reading skills to EFL students. It is a qualitative paper which examines and underscores the usefulness of developing EFL reading comprehension skills by using the CLIL teaching. The outcome of this teaching and learning methodology is predicted and determined by presenting and evaluating considerable researches carried out in this field by eminent language researchers. These studies unequivocally demonstrate that the application of CLIL in classrooms with regard to the acquisition and retention of EFL reading and vocabulary skills among college students has proved to be very helpful and palpable. It must be understood that CLIL does not help in making the teaching content simple or revising what learners already know. CLIL courses actually blend language and content together so as to enhance the language as well as the thinking abilities of the learners. The significant amount of research interest in this subject and its growing demand as a foreign language teaching approach necessitate intensive research and analysis as to its efficacy in other parts of the world. In this context, this paper examines and validates its efficacy for the Saudi EFL learners, in view of its ostensible advantages related to language awareness and content knowledge. This paper aims to address the problems and concerns of Saudi learners and teachers of EFL, and lays down the plans to implement CLIL courses in Saudi universities for the benefit of the students in this part of the world. The research concludes by encapsulating and analyzing the researches undertaken in this field and explaining the lessons learnt by employing CLIL courses at the graduate and undergraduate levels in Saudi universities.
