The "OneSky" early childhood intervention programme, delivered by Half the Sky Foundation, aims to promote early childhood development and maternal-child interactions in rural China. The overarching goal of Half the Sky is to ensure every child receives the loving care and nurture necessary for not only surviving but thriving in today’s society. The Intervention programme includes three component: Family Skill, Preschool, and Community Engagement. Family Skills component for children aged 6-36 month and their caregivers; Preschool component for children aged 3-6 year; Community engagement component provide community support to children aged 0-6 year.
We will evaluate this programme. Evaluation will be by cluster randomised controlled trial. We will assess child development and conduct household and village surveys before and after the intervention on a sample of n=4000 children in 60 villages in Ye County, Henan Province, China.

Experimental Details
Half the Sky Foundation will carry out its Responsive Care Model intervention that aims to improve the effective interaction between mothers and their infants in everyday activities. The Intervention comprises of three village-based interventions: by introducing a center-based curriculum that follows the developmental stage of the child. The curriculum will be delivered by local staffs during weekdays to 4000 children, aged 6 - 36 months at the start of the intervention, and their caregivers in the centers. Family Skills component will provide weekly group sessions at the Family Center (refurbished village meeting hall), and teachers in the centers will teach primary caregivers how to enhance their interaction with their infant and toddlers. Locally recruited and trained Parent Mentors will hold weekly group sessions to discuss, demonstrate and practice responsive care activities. They will also conduct regular home visits. During implementation period, 2000 children aged 6-36 month and their caregivers will participate in a total of 40 family sessions and 12 home visits. Preschool component will make sure that those existing preschools in the villages will be refurbished, with age appropriate equipment and materials. Half the Sky trainers will train the teachers in 3 sessions (training/practice/feedback). The content is based on child centered, activity based learning with emphasis on building socio-emotional relationships with adult and children. There will be 2000 children aged 3-6 years participating the Preschool component. Community component will provide help to increase the village community harmony, which will provide a good environment for children.

Experimental Design Details
Randomization Method
The randomisation is conducted by a computer in the office, using the statistical program Stata version 12. The steps we follow are:
1. Identify sample of eligible slums:Exclude those villages which are not feasible open programme in there.
2. Block sample of villages: block based on common observed characteristics;
3. Randomly sample 30 villages;
4. The matched paired are drawn at random from the same block.
