Abstract T he present study aimed at investigating the effectiveness of critical thinking techniques for improving EFL reading skills. The design of this study is a pre-post, experimental-control group. The experimental group students were taught using critical thinking techniques, while the control group did not receive any training except the regular method. The main question raised in this studywas what is the effect of critical thinking techniques in improving EFL reading skills?To this end, the researcher collected data througha reading test and a rubric for correcting it, prepared by the researcher, and judged by the jury members. The reading test was applied to the study sample before and after the implementation. The results of the study revealed that EFL reading selected skills “inference, evaluation, and recognizing vocab." improved among experimental group students because of using critical thinking techniques “debate, problem-solving, self, and pair assessment". This reveals the effectiveness of critical thinking techniques in developing EFL reading skills among Jazan University students. The researcher recommends using new techniques to develop EFL reading skills.
