This is the website of the School Readiness Indicators Initiative. This is a US multi-state initiative that uses child well-being indicators to build a change agenda in states and local communities in order to improve school readiness and ensure early school success. The initiative objectives are: to create a set of measurable indicators related to and defining school readiness that can be tracked regularly over time at the state an local levels; to have states and local governments adopt this indicators-based definition of school readiness, fill in gaps in data availability, track data over time and report findings to their citizens; to stimulate policy, programme and other actions to improve the ability of all children to read at grade level by the end of the third grade. This resource contains key news, updates and critical information materials. Although the focus is on the US, research on indicators and lessons learned can be adapted for other contexts
