20+ Topic Ideas for a Diagnostic Essay and How to Write One

When students are given the assignment to write a diagnostic essay, they are terrified by the name and question how or what the diagnostic essay definition is. Frankly, a diagnostic essay is not the same as a standard essay. Its goal is to assess or diagnose a set of competencies that all college students should possess. It is usually administered by college professors at the start of the academic year to assist teaching staff in evaluating existing knowledge of a specific student or course audience. There are certain rules and things to check, as with every assignment, which we will go over in our diagnostic essay guide.

What is the definition of a diagnostic essay?

Diagnostic essays are exercises that present a known topic or pose a question that must be responded to in an essay form for the majority of university courses in the United States. Because most people's time is limited, diagnostic essays can be difficult to write, especially when deadlines are tight and there isn't much time to consider. Because of time constraints and stringent deadlines, there is no need to conduct any study.

The objective of a diagnostic essay is to assist teachers in evaluating students' talents, writing styles, and determining their level of knowledge. It is not necessary to demonstrate that you have read specific books or conducted extensive study. Diagnostic essays are similar to timed creativity tests in that they aid in the discovery of skills and limitations. When a document is finished, college and university teachers review it and make suggestions, writing advice, and comments on key errors. These elements are really crucial to consider, from grammar to formatting regulations! Furthermore, teachers plan their own work and assignments based on the level of skills demonstrated by each student.

Even though such projects are rarely marked, they must be completed in such a way that teachers can notice the students' abilities to work on preparation, essay writing, reasoning, strategic thinking, and editing! Remember that decent proofreading abilities are also required!

Format and Structure of a Diagnostic Essay

Remember that your time is limited, thus it's critical to focus on proper organization first! This method will assist you in avoiding further editing or rewriting issues. Unless otherwise specified, typical diagnostic writing should consist of an introduction, three body paragraphs, and a conclusion.


To introduce the allotted topic or question, repeat the request in your own words. Then, in a few sentences, describe three important ideas (arguments) that will be discussed in the body paragraphs. The thesis statement, which should be one sentence long and convey a powerful argument or a call to action, is the last sentence in an introduction.

3 paragraphs in the body

Remember the classic adage, "One idea, One body paragraph!" It's a requirement here! Make a case for your point of view, and explain how it pertains to your thesis. Feel free to include any facts, research, or personal experience that can be utilized to back up the various statements being presented.

The conclusion

Summarizing each paragraph's essential points in a way that makes even the most complex information more understandable. In the concluding paragraph, do not offer any new concepts. Rephrase the thesis statement in alternative phrases so that the target audience has no doubts. In your concluding line, discuss facts or an issue in such a way that it motivates people to act favorably or to learn more about the essay topic.

  • When representing various ideas and arguments, remember to be as specific as possible.
  • Avoid using generic statements and instead provide examples that demonstrate the teaching staff that you are prepared for the task at hand and that you have strategic thinking and analyzing skills.
  • Always attempt to write in short, logically correct sentences because this makes editing and proofreading easier. Furthermore, with a stringent word count, items can easily exceed the limit!

Step-by-Step Instructions for Writing a Diagnostic Essay

When you discover more about the required format and a list of items to consider, knowing how to write a diagnostic essay will become much easier. To demonstrate good writing skills, this type of writing must be accurate and well-structured. Academic experts utilize such assignments to assess your ability to deal with structure and analysis. As you begin writing your diagnostic essay, keep the following in mind:

  • Pick a topic that interests you.

You must either respond to a prompt that has already been supplied or find something that inspires you. Consider writing about the difficulties students have had when learning remotely or discussing societal issues such as racial discrimination. The topic should pose a question or represent a significant problem so that you can "diagnose" the situation and give some of your ideas.

  • Create a compelling thesis statement.

A excellent thesis statement implies that you should contemplate some idea that displays your viewpoint on the subject. A thesis statement is a statement that summarizes or explains your point of view. It is suggested that you begin with your thesis statement. Consider a list of reasons and arguments to back up your position. It must include the "because it..." component, which backs up your claim.

  • Make a rough outline.

Of course, if you're short on time, you may skip this section, but it can help you stay organized and ordered in your thinking. It's an excellent technique to jot down any thoughts that come to mind so you don't forget them while writing. Each paragraph must include only one idea. You won't go over your word limit or make your selected topic too broad if you follow this rule.

  • Consider the introduction.

You must begin your diagnostic essay with a hook sentence or a memorable phrase that will pique the interest of your readers. Remember to begin by introducing your topic and explaining what it means or why it is important to society. This is also the paragraph in which you should state your thesis. It ought to be linked to your thesis statement. Otherwise, it can come across as odd, which isn't a good thing!

  • Body Paragraphs With Topic Sentences

Unless otherwise indicated, you should include at least three body paragraphs. This is where you can provide any important facts, such as real-life stories, examples, statistics, or statistics. Provide proof to back up your point of view. Always give credit to the original author if you use any sources.

  • Conclusion.

This is the section where you must summarize your ideas and opinions. Your argument, on the other hand, should be written in alternative words or in a sentence that makes it clearer. No new concepts should be introduced. Simply state all of the major results as if you were completing the bullet points. Avoid repeats and keep your sentences short; your conclusion should account for roughly 10% of your entire word count.

  • Editing and proofreading

This section should never be overlooked because it aids in the prevention of both significant and minor errors. Learn to read your essay aloud and begin by revising before moving on to proofreading (this part determines how good it sounds). Always be critical and double-check your work using your grading rubric or prompt!

Fortunately, writing a decent diagnostic paper is not as difficult as writing other types of essays you may encounter in college. You are not required to conduct research or to synthesize data from diverse academic sources. You can, of course, include some external data or statistics, but you don't have to if it isn't essential. The most important thing is to be inspired as you begin writing and to use proper language and structure to create content that is logical, fascinating, and easy to understand. Before we get into the top 25 diagnostic essay themes, let us remind you that at Eprowriters, your papers will always be delivered on time!
