Social media has increased students' cultural awareness today, pivoting a need to implement cultural responsiveness in the classroom climate. Twenty-first-century learners need effective teachers who create meaningful experiences and optimize student learning by intentionally working to connect with students, adapting to diverse cultures, and using new strategies to deepen their practice. The most significant demand for culturally responsive teaching (CRT) is in secondary education. Data has shown that educators can promote the best interest of students by creating more equitable classroom strategies to increase motivation, engagement, and classroom effectiveness. If teachers and educational leaders are to evoke true educational reform and thus close achievement gaps exacerbated by the global pandemic, they must employ culturally responsive pedagogical practices. By implementing these strategies, educational leaders will reinforce actions taken for the student's best interest. This literature review aims to explore and identify the impact of CRT on student achievement in secondary schools.
