This study aimed at analyzing the cognitive levels of the wh-questions following the reading texts in the Students' Book of Flying High for Saudi Arabia One. A Checklist based on the revised cognitive domain of Bloom's Taxonomy was the instrument used to categorize the cognitive levels of these questions and to determine to what extent they are included properly in the Student's Book of Flying High for Saudi Arabia One. The main findings revealed that the wh-questions following the reading texts which are included in the textbook under analysis were not properly included. Also, the authors of the textbook overemphasized the lower thinking skills and neglected higher thinking skills. Such study is recommended to shed light upon the role of the other series of Flying High for Saudi Arabia in developing cognitive skills among secondary Saudi students.
