A great deal of weak writing on An Inspector Calls begins with a weak first sentence. Students often open with background on the author, a summary of the plot or a restatement of the question. None of these gives the essay a direction.

A thesis is a claim that the rest of the essay proves. For a play as focused as this one, it can be short. It only needs to say what the student believes Priestley is doing with the topic in the question and why.

Marking becomes easier when the thesis is clear. You know what to look for in each paragraph, and you can judge whether the essay stays on course.

The following approach helps students get there.

From topic to claim

Most exam questions name a topic, such as the presentation of Sheila or the theme of responsibility. Students should turn that topic into a claim by adding a verb and a reason. For example, "Priestley presents Sheila as a hopeful figure because her willingness to change contrasts with her parents' refusal." The sentence is simple, and it gives every later paragraph a job.

• Start with the question's key word, then make a claim about it
• Include a because or a so that to show purpose
• Avoid vague verbs such as shows or explores without a follow-up
• Keep it to one or two sentences in the introduction
• Return to it, in new words, in the conclusion

Assessing the thesis quickly

A three-question check works well. Does it answer the question? Could someone disagree with it? Does it point toward the writer's purpose? If the answer to any is no, the student has a topic, not a thesis.

You can mark this in seconds on a first read. It is often the most useful predictor of the rest of the essay.

Common thesis problems

The problems are predictable. Some are too broad, such as "Priestley shows that society is unfair." Others are too narrow, like a claim about a single quotation. A third kind restates the question with no position at all.

A brief comment showing how to narrow or widen the claim is usually enough. Students can often fix the sentence in a minute if they see the problem.

Practice and feedback at scale

Thesis practice works well as a short daily task. Students write one or two sentences in response to a question and get quick feedback. AI-assisted tools such as GraideMind can apply a rubric to short responses like these and draft brief comments, which you can review and return the same day.

A few weeks of this kind of practice tends to raise the quality of every later essay, since students learn to decide what they think before they begin writing.
