The availability of prenatal care, including prenatal screening and diagnosis, has played a part in reducing the frequency of maternal death, miscarriages, birth defects, low birth weight, neonatal infections and other preventable health problems.

Methodology: Quantitative research approach will be used one group pre-test post-test design for the study. The sample size was 50 for final study and its 10% i.e., for pilot study. Non- Probability Purposive sampling technique was used to select study sample. Data was collected by using demographic variables, Self-structured knowledge questionnaire, observational checklist and Objective Structured Clinical examination. The pilot study was done by the researcher in Modern nursing college, Shimla, Himachal Pradesh. The final study was conducted by researcher in Shimla Nursing College, Shurala, Shimla Himachal Pradesh. Data analysis was planned descriptive and inferential statistics.

Result: The findings of the study revealed that Pre-test mean was 15.06 with standard deviation 2.298 and Post-test knowledge mean was 24.24 with standard deviation 2.825. Result showed that mean Post-test knowledge score was higher than mean Pretest knowledge score at paired ‘t’ value = 20.374 which was significant at 0.05 level of significance. There was no association of knowledge score found among nursing students with selected demographic variables. Pre-test skill (Observational checklist) score mean was 9.38 with standard deviation 2.127 and Post-test skill score mean was 16.54 with standard deviation 2.315. Result showed that mean Post-test skill score was higher than mean Pre-test skill score at paired ‘t’ value = 22.938 which was significant at 0.05 level of significance. There was no association of skill score found among nursing students with selected demographic variables. Pre-test (OSCE) score mean was 12.64 with standard deviation 3.262 and Post-test (OSCE) mean was 21.76 with standard deviation 3.172. Result showed that mean Posttest skill score was higher than mean Pre-test skill score at paired ‘t’ value = 15.003 which was significant at 0.05 level of significance. There pre-test skill (OSCE) association was seen between occupational status of father and occupation status of mother. There was no significant association of skill is found among nursing students regarding antenatal care.
