Community based monitoring in ICDS involves periodic follow up of programme implementation by community members to check coverage, quality of services, and address community needs. It increases accountability, generates information through community involvement, and strengthens local decision making and community capacity. Monitoring is done by Bal Vikas Mahila Samitis at village, block and district levels, involving elected representatives, officials, and community leaders. Areas monitored include functioning of anganwadis, supplementary nutrition, health services, and community participation. Review committees have also been constituted at national, state, district, block and anganwadi levels to oversee monitoring.
