Objectives: The purpose of this study is to assess the knowledge regarding prevention of Sexually Transmitted Diseases (STD’s) among Adolescent students in selected high schools, Aizawl, Mizoram. Methods: Evaluative research approach was used in which one group pre-test post-test design was used as a research design. As for the study 100 Adolescent high school students were selected using simple random sampling technique in a selected high school, Aizawl, Mizoram. Results: The study assessed STD knowledge across different demographics using Chi-square tests, categorizing knowledge into Inadequate (0–7), Average (8–11), and Adequate (>11). A significant association was found between age and knowledge levels (p = 0.0356), with older students (17–18 years) showing the highest adequate knowledge, suggesting age and maturity contribute to awareness. However, no significant difference was observed between Class IX and Class X (p = 0.8482), indicating grade level alone does not influence knowledge. However, family structure showed significant effect (p = 0.0023) on the knowledge. Prior knowledge did not significantly impact post-intervention results (p = 0.2165), highlighting the effectiveness of structured education over informal sources. Additionally, the source of STD information (e.g., teachers,family,peer group, mass media) showed significant impact on knowledge levels (p = 0.0093), implying source from the teacher was dominant. Overall, age, types of family and sources of information was the factor significantly linked to knowledge. Conclusion: The study concluded after administering Planned Teaching Program (PTP), there is improvement in knowledge among the Adolescent high school students regarding prevention of Sexually Transmitted Diseases (STD’s). Hence, it is statistically interpreted that Planned Teaching Program (PTP) was effective for the improvement of knowledge regarding prevention of Sexually Transmitted Diseases (STD’s) among Adolescent high school students.
