PurposeThe study aims to assess the impact of electronic learning (e-learning) on students' performance (SP), with an emphasis on the mediating role of sustainable education (SE) at the Sharjah Police Sciences Academy (SPSA). The urgency of this study was highlighted by the global COVID-19 pandemic that happened between 2020 and 2022, which emphasized the need for e-learning as a tangible and imperative solution.Design/methodology/approachThe study applied a quantitative approach, targeting the 91 student population at SPSA in the winter semester of 2022/2023 who practiced the e-learning process. A comprehensive survey was implemented disseminating 91 questionnaires by Google Forms to all students. Of the total, 61 questionnaires were returned, resulting in a response rate of 67.03%.FindingsThe results revealed that e-learning predictors explained 85.4% of the variations in SP, and 46.4% of the variations in SE. The model demonstrated a strong fit and high predictive relevance. The indirect impact of e-learning on SP through SE was found to be positive and statistically significant at the 0.05 level. Consequently, the mediation effect was considered partial and statistically significant.Practical implicationsPolicymakers and educators should consider findings of the study when designing educational programs and policies. Accordingly, the SPSA management could gradually focus on safeguarding a sustainable e-learning environment and improving high-tech platforms. This would involve creating a sustainable e-learning curriculum to enable students to remain informed on the best e-learning practices.Originality/valueAn empirical study is essential for exploring the optimal answers to inquiries related to e-learning, SE and their impact on SP. The finding of the current study may contribute to the existing knowledge on e-learning, SE and SP. Additionally, they may improve learning activities and provide more sustainable learning experiences, leading to enhanced learning outcomes for students
