State and explain the issue in question at the beginning of your platform essay. For example, your area of focus may be animal rights. Give background information on the state of animal rights in your area or country. Include well-supported statistics to make your point stronger.
Explain how the issue in question has affected you personally. Did you hear of animal rights abuses and decide to become a vegetarian? This aspect of your platform essay is important in supporting your current position on the issue. You have an opportunity to communicate to the reader that the issue has had a personal impact on you, making it a concrete experience instead of an abstract idea.
State your position clearly. If you are against animal testing in the cosmetics industry, say so in as few words as possible. The rest of your platform essay will explain why you have taken your position, and you will also detail your plans to take action on the issue in question.
Identify the ways in which you have worked to support your position. Do you volunteer at an animal shelter? If you have not yet taken action, describe your plan to act on behalf of the people or animals affected by the issue you have chosen. Will you begin a letter-writing campaign to local and national government? Will you organize a volunteer group to make a positive difference in the lives of senior citizens? The more concrete steps you can provide, the better.
