High school graduation is a celebration of your transition from a child to an adult.
In general terms, graduation is considered a rite of passage. A rite of passage is a ritual or ceremony that marks one stage of a your life to another. Baptisms, marriages, a retirement from a job or occupation, and funerals are other examples of rites of passage that are celebrated in our society.
But as time progresses, certain rites of passage undergo a transition and slowly fade into disuse. Religion plays a smaller role in our secular lives. Outside of a few religions such as Judaism, there are no events that mark the transition to adulthood. With the divorce rate at 50% in Canada, and the growing number of common-law relationships, marriage too is not seen as an enduring transition in your life. Finally, dramatic changes are occurring in the workplace. Fewer people spend their entire lives working for one company. A greater number of people work multiple part time jobs and fulfill temporary contract positions. With many continuing to work into their senior years, retirement is a rite of passage that is diminishing in significance.
But without a doubt, high school graduation remains an important rite of passage and its significance as a transition from child to adult is increasing. Without a high school diploma, the chance of obtaining satisfying and gainful employment is minimal.
But high school graduation is more than just a means of acquiring a better job. As a child in school, society has given you everything it can to protect you, guide you and help you find your way in the world. It is now hoped that you will reciprocate and give back to society. This is the transition that high school graduation celebrates.
