Teaching elementary students how to read is undeniably crucial, yet a substantial number of children encounter difficulties despite early interventions. Cross-age tutoring, a pedagogical approach that pairs older students with younger peers, emerges as a cost-effective solution that brings academic and social benefits to both the tutor and the tutee. Consequently, cross-age tutoring programs are widely adopted globally. To maximize the effectiveness of cross-age tutoring, we offer five evidence-based recommendations tailored for its implementation. When integrated into the preparation and implementation steps, these recommendations hold the potential to significantly improve learning outcomes for both tutors and tutees.
