 We will conduct a cluster randomised trial CRT of 320 villages in one district of Bihar State, India. The unit of treatment allocation will be villages, as some villages have more than one school. We expect selection of 320 villages to result in about 400 eligible schools. Schools are eligible to receive the intervention if they have more than 150 children enrolled in the school register. 160 villages will be randomised to receive the intervention at the beginning of the study before assessing the study outcomes intervention schoolsvillages and 160 will be randomised to receive the intervention at the end of the programme after completing all research activities control schoolsvillages.
