The study was largely a quantitative survey involving a large number of secondary school teachers as respondent’s thus the data collection method adopted was a survey which involved the use of selfadministered questionnaires (SAQs). The research study targeted the students, marriage couples, teachers and institutions and village leaders totaling to 50 respondents. From the findings, more than sixty percent (64%) of the respondents in the research sample disagreed that in order to become independent the school girl becomes pregnant. This result is contrary to most research that found that by falling pregnant the adolescent schoolgirl perceives herself as an adult and thus independent concerning physical and sexual aspects (Bolton, 2003). These respondents might see a pregnant schoolgirl as still dependent as she still needs financial support to complete her education and care for the baby as well as someone to look after the baby during school time. Parents should counsel their daughters once they reach adolescent stage and equip them with necessary materials such as sanitary towels, books and little pocket money for lunch to protect them from the lures of businessmen and also teaching them on how to overcome teenage pregnancies.
