This instrument was used to collect primary data from mothers and children participating in the project. The mother’s survey covers household socioeconomic characteristics, digital connectivity, mobile phone access and usage, mobile financial services, women’s agency and decision-making, gender attitudes, digital literacy transfer, economic empowerment (using a WEAI-based module), parental involvement in children’s education, and educational aspirations for children. A separate children’s assessment measures foundational learning outcomes in Bangla, English, and Mathematics, with age-appropriate question sets assigned by grade group (Classes 4–5, 6–7, and 8). The instrument was administered in person by trained enumerators in rural Bangladesh.
