<u>A persuasive speech</u>.
A persuasive speech is defined as <em>a specific type of speech in which the speaker has a goal of convincing the audience to accept his or her point of view</em><em>. </em>Since what you're looking for is to <u>convince</u> your audience not to drop out of school, then this speech would be the most appropiate.
