Writing effective evaluations is an important skill that you will use not only in college but frequently in your career and everyday interactions. Think about it: every time you are presented with someone's opinion, either verbally or in written form, you engage in the process of evaluation to decide whether or not you agree with the opinion. At work, you may evaluate a business strategy. At school, you may evaluate the impact of an important invention. At home, you may evaluate the quality of a new appliance you just purchased.
