Abstract: The emergence of the National English Curriculum Standards (2017 Edition, Revised in 2020) has sparked widespread attention and resonance in the field of secondary school English teaching. Delving into the study and application of the new curriculum standards has become a crucial entry point and lever for secondary school English teachers to renew their teaching philosophies, enhance teaching effectiveness, and advance the depth of education. The new curriculum standards provide important guidance on how secondary school English teachers should teach, how students should learn, and how to effectively integrate teaching, learning, and assessment, thereby delineating the direction of English teaching in the current era of emphasizing subject core literacy in quality education. The 2022 Compulsory Education Curriculum Standards explicitly mention the curriculum design concept of "integrating teaching and assessment," further deepening the intrinsic connections among teaching, learning, and assessment. Therefore, based on the guiding principles of "integrating teaching and assessment," this paper relies on the 2017 edition of the new curriculum standards and combines the practical situation of secondary school English teaching to analyze how to comprehensively understand the connotation of "integrating teaching and assessment" and how to implement effective teaching and assessment practices.
