Creating a good thesis statement is important, as a thesis shapes your entire essay. A thesis statement is the groundwork for the path your writing will take, so it is important to make sure your statement is clear and it directly addresses the topic or standpoint you choose. You must first decide which point you intend to argue. Do you believe anti-bullying strategies in schools are effective, or not? You must then be specific in your statement: is your thesis statement something one could argue against? Be sure you aren't just summarizing the given topic. For example:
Anti-bullying strategies used by schools are effective in deterring bullying issues by creating student awareness of potential problems and providing effective strategies that students can use to help themselves or others in a bullying situation.
Be sure your thesis doesn't leave the reader asking "how" or "why"—if it does, your thesis may be too vague.
