We find that the process measures of the quality of the prenatal and child care processes are positively and significantly associated with child growth. Structural quality and access variables, however, are not associated with child growth. These findings suggest that investments in improving prenatal and child care process quality in existing facilities in Indonesia may be an effective way to address conditions that result in a child’s inability to reach full physical potential. This paper is organized in four sections. We first present our model for analysis and its assumptions.
