The study was conducted at Anganwadi centres, Tirupati. Population includes mothers of under-five children. Sample size consists of 100 mothers of under-five children under inclusion criteria. Non-probability convenient sampling technique was adopted based on inclusion criteria. A structured knowledge questionnaire is used to assess the knowledge regarding ICDS services among mothers. The collected data were analyzed by descriptive and inferential statistics. Study findings revealed that out of 100 mothers 53(53%) had moderate knowledge, 38 (38%) had adequate knowledge and only 9 (9%) had inadequate knowledge regarding ICDS services. The mean knowledge regarding ICDS services among mothers is 23.14 with the standard deviation of 4.362.
