The research instrument used was documentation, which was validated by three English lecturers with a Content Validity Index of 0.77, indicating an adequate level of reliability and validity for use in research. The research results show that the book "Smart Path to Learning English for SMK/MAK Class X" does contain 4Cs skills, but with varying levels of involvement. Critical thinking skills are identified through several activity that encourage students to deploy, disseminate, and clarify information. Creativity skills are seen in activity that require students to write and express their creativity through the answers they give. Aspects of collaboration are found in some activity and are displayed in the form of the exercise process; however, collaboration skills are not fully integrated into the exercises. Communication skills are found in several activity that focus on oral communication in group discussions. Overall, this research concludes that the textbook "Smart Path to Learning English for SMK/MAK Grade X" has integrated 4Cs skills in several activity, but not evenly. Some activities are stronger in covering the 4Cs skills than others, with critical thinking and creativity skills more prominent in some activity, while collaboration and communication are less visible. To increase effectiveness, it is recommended that aspects of collaboration and communication be integrated at various stages of learning, both at the beginning, middle, and end of learning sessions, to ensure students are accustomed to using these skills in various contexts.
