Emirati children’s reading skills have consistently lagged behind global standards on international standardized tests. Given the United Arab Emirates’s Vision 2031, which aims for a world-class education system, and given the importance of Arabic literacy in preserving national identity and cultural heritage, there is an urgent need to investigate the factors that influence Arabic literacy among Emirati children. Therefore, this study, using data from the Progress in International Reading Literacy Study (PIRLS) 2016 database, aimed to examine the relationships between parents’ attitudes toward reading, early literacy activities, early literacy tasks, and Arabic literacy. Specifically, the study aimed to (1) determine the predictive value of parental attitudes toward reading for Arabic reading literacy among Emirati children; (2) examine how early literacy activities and tasks contribute to Arabic reading literacy; and (3) examine the mediating role of early literacy activities and tasks in the relationship between parental attitudes and Arabic reading literacy. The results of the study suggest that parental attitudes toward reading are an important predictor of their children’s Arabic reading literacy. Participation in early literacy activities before primary school and mastery of early literacy tasks at the beginning of primary school were both associated with reading proficiency in Arabic. Furthermore, both early literacy activities and early literacy tasks significantly mediated the relationship between parental attitudes toward reading and children’s reading proficiency in Arabic. The findings are critical for educators to adapt teaching methods, curricula, and parental involvement programs to more effectively support Arabic literacy development. The study highlights the need for an inclusive approach involving parents, educators, and policymakers to create an enabling environment for the development of Arabic literacy, which is essential for academic success and cultural preservation.
