3 and ends at age 6, the theoretical duration would be 3 years.", "Data on pre-primary education duration are collected from national legislation and formal education standards, and are mapped to the

children may not attend school for the full duration.", "Changes in national education policies, such as extending or reducing the years of pre-primary education, can impact this indicator and should be considered when analyzing trends over time.", "This indicator is useful for understanding government commitment to early childhood education and for planning resource allocation, but it should be
