This study aims at analyzing "Unlock English Reading, Writing and Critical Thinking Skills" Textbooks (First and Second editions) in terms of the inclusion of the lower and the higher order thinking skills. The current study is a descriptive content analysis paper that followed a checklist containing the cognitive levels of Bloom's Taxonomy as well as a checklist of the possible verbs by OPAR (2012) that combined the Revised Taxonomy as well. The finding in this study indicated that majority of the cognitive objectives in the second edition belong to both LOTS (Comprehension) and HOTS (Analysis and Synthesis) whereas the focus of the first edition was mainly on Comprehension and Analysis. Some objectives, also, were paraphrased to reflect the cognitive objectives where they were more related to reading comprehension sub-skills (skimming, scanning, previewing, etc.). Based on the findings, some recommendations were listed.
