Research appropriate sources to determine if your thesis statement clarifies your position and defines a direction for your paper.
Revise your thesis statement so it is not too broad for focused research -- but broad enough to promote various resources. Make sure it is narrow enough for in-depth research. Ascertain that your thesis statement is original enough to keep you and your reader interested. Make sure it offers insights and information substantive enough to be worthy.
Evaluate to determine if your thesis statement acts as a working hypothesis, an idea statement or approach that forms the foundation of your thesis.
Put your thesis statement on paper to help you see your proposal in clearer and more logical terms. Others must be able to disagree with your assertion or claim statement.
Focus on a thesis statement consisting of two parts -- the analysis and explanation of your proposed insight or argument and your assertion supported by evidence. Evaluate your thesis statement to make sure it is well-defined and relates only to your essay's discussion that remains supported by precise evidence. It must prepare the reader for your paper's body and hint at its conclusion.
Evaluate your ability to convince the reader that your claim is valid by giving reasons and evidence. Determine the order you offer evidence and the reasons behind your thesis statement. For example, exterminators should not get rid of bats at city hall because bats aid in the elimination of mosquitoes and rats in the city. The reader of this thesis statement expects your argument and evidence regarding the reasons exterminators should not get rid of bats at city hall.
Describe in your thesis statement what your ideas are about, and what your ideas are (your angle). Ensure that your thesis statement concentrates on these two basic elements. For example, in the aforementioned thesis statement your ideas are about the extermination of bats at city hall and your angle is that bats help eliminate city pests like mosquitoes and rats.
Identify individual insight about your thesis statement with your angle, which reflects your own ideas, argument, analysis and interpretation of the topic.
