1. To assess the existing knowledge on selected child welfare programme in India among mothers of under five children by pre-test score.

2. To find the effectiveness of structured teaching programme regarding selected child welfare programme in India among mothers of under-five by post-test score.

3. To determine the association between the pretest knowledge scores of mothers with selected demographic variables.

Methodology: Pre experimental design with one group pre test and post test design was adopted to evaluate the effectiveness of structured teaching programme on selected child welfare programme in India among the mothers of under five children in selected urban area at Saidapet. 60 samples were selected by using non-probability convenient sampling technique. A structured questionnaire was prepared and was used to collect the data and to assess the knowledge on selected child welfare programme in India. The tool consists of 9 demographic variables and 40 structured knowledge questionnaires. The data obtained was analyzed and interrupted in terms of the objectives and hypothesis of the study. Descriptive and inferential statistics were used for the data analysis.

Result: In pretest, out of 60 mothers of under five children 44(73.3%) had inadequate knowledge and 16(26.7%) had moderately knowledge and none of subjects had adequate knowledge. In post test, out of 60 mothers of under five children, 41(68.3%) had adequate knowledge, 19(31.7%) had moderately adequate knowledge and none of the mothers of under five children had inadequate knowledge. Enhancement was computed by using paired ‘t’ test at 0.05 level of significance and it was found to be 31.68, indicating that there is a significant improvement in the knowledge of mothers of under five children. There is statistically significant association found between two demographic variables and pre-test level of knowledge on selected child welfare programmes. The variable education status of mother showed significant at p<0.05 level of significance with chi-square value 12.97 and the variable previous knowledge showed significance at p<0.05 level of significance with chi-square value 8.12.
