Find something to evaluate. Brainstorm possible topics to evaluate by making a list. For example, you might make a list of movies, films, books or policies to evaluate. Decide on a topic and then further your brainstorming with an expanded list of details about the topic.
Draft a thesis statement. The thesis details the overall purpose of the evaluation essay and sets up the angle for your judgment. In evaluation essays, the thesis should argue the value or lack of value of your particular topic based on the criteria you will later establish.
Define your subject. Provide background information about your topic or subject before you begin evaluating. For example, when evaluating a book, provide a brief summary of the plot and its characters to set up the context of the evaluation for the reader.
Choose the appropriate criteria. In order to evaluate a topic or attempt to pass judgment, writers need to detail criteria in which the topic will be evaluated. For example, if you are evaluating a movie, the criteria might be cinematography, plot, action, realistic characters or visual effects.
Critique the criteria. When drafting evaluation essays, the body of your essay should address the effectiveness or ineffective qualities of each set of criteria. Provide examples to support your judgment of each criteria and argue in accordance with your thesis.
