A Thousand Days-A programme for vulnerable early childhood in Argentina: Targeting, dropout risk factors and correlates of time to graduation.

Mil Días-San Miguel is a programme for early childhood development in Argentina, which was pioneer when it was first introduced. It is well targeted and exhibits encouraging results despite complex cases taking longer to sucessfully exit the programme. In addition, the poorest poor participants are more likely to abandon the programme and so additional actions could be taken to retain them, as intended by the 'Leave No One Behind' 2030 commitment.
