H1: There will be a significant difference between pre-test and post-test knowledge score regarding water birth among 3rd year GNM students.

H2: There will be a significant association between pre-test knowledge score with selected demographic variables of 3rd year GNM students regarding water birth.

Methods: A pre-experimental approach was used for this study. The study was carried out in selected nursing schools in Ramanagara. The research design was pre-experimental one group pretest post test Research Design. The sample comprised of 100 3rd year GNM Major findings and results. The pre-test mean percentage knowledge score was shows that highest mean of subject is 10.56 with standard deviation is 2.1039 and mean percentage of 35.20% obtained for knowledge on 3rd year GNM students and the post test study shows that highest mean of subject is 10.56 with standard deviation is 2.1039 and mean percentage of 35.20% obtained for knowledge on students, knowledge regarding water birth. The association of Paired t Test is accepted because a calculated value is 48.1171 and df is 99, hence it is more than calculated value. So Null hypothesis is rejected and Research hypothesis is accepted. The χ2 value computed between the pre-test level of knowledge with selected socio-demographic variables. Variables of age (χ2 = 0.01), Religion (χ2 = 0.07), Variables of Occupation of Father (χ2 = 0.15, Variables of occupation of mother (χ2 = 0.03), type of family (χ2 = 0), 01, Variables of monthly income of family (χ2 = 0.12), Variables of source of information of water birth (χ2 = 0.03), were found to be not significant at 0.05 level. Thus it can be interpreted that there is no significant association between pre-test levels of knowledge of 3rd year

Conclusion: The above table shows the pre-test score level of knowledge of mothers, in which 50 (50.0%) were had poor knowledge, 48 (48.0%) were had good knowledge, and 02 (02.0%) were had Excellent knowledge water birth among nursing students. The above table shows the post-test score level of knowledge of mothers, in which 93 (93.0%) were had Excellent knowledge, 04 (04.0%) were had poor knowledge, and 03 (03.0%) were had good knowledge water birth among nursing students.

Implications of the study: The findings of the study can be used in the following areas of nursing profession
