Plenty of students know An Inspector Calls well enough for a Grade 9 but write answers that land on a 6, because they describe the play instead of arguing about it. This page shows the difference, with the opening of a Grade 9 answer on social responsibility and a note under each part explaining what earns the marks. Because the play is in copyright, the quotes are kept short.
What makes a Grade 9 essay
Three things lift an answer into the top band here. First, a clear argument that runs through every paragraph. Second, precise analysis of short, well-chosen quotes. Third, and especially in this play, context used as meaning: showing that Priestley is writing in 1945 to persuade his audience, not just telling a story. The model below does all three.
An annotated Grade 9 model
The question: how does Priestley present ideas about social responsibility? Here is the introduction and first body paragraph, annotated.
Priestley uses An Inspector Calls to argue that social responsibility is not a choice but a duty we owe to one another. He constructs the entire play as a rebuttal of Mr Birling's selfish individualism, using the Inspector as his own voice to insist that, in a just society, no one can look after only themselves.
Why it scores: the introduction states a clear, arguable thesis and names Priestley's method (constructing the play as a rebuttal). It treats the play as a deliberate argument, not a story, which signals top-band thinking from the first line.
Priestley first gives his opponent the stage. Birling's claim that "a man has to mind his own business and look after himself and his own" is placed deliberately at the start, before the Inspector arrives, so that the rest of the play can dismantle it. The possessive "his own" exposes the narrowness of his care, and because the 1945 audience already knows Birling is wrong about the Titanic and the war, they are primed to reject his politics too.
Why it scores: the paragraph analyses a short quote closely (the possessive 'his own'), explains Priestley's structural choice (placing it first to knock it down), and folds in context (the 1945 audience, the dramatic irony) so that AO3 deepens the argument rather than sitting apart from it.
Against this, the Inspector offers Priestley's alternative. His declaration that "we are members of one body" answers Birling directly, replacing the individual with the collective. The metaphor of a single body makes irresponsibility not just wrong but self-harming, since to damage one part is to damage the whole.
Why it scores: this turns the argument forward by setting the Inspector directly against Birling, and it digs into the 'one body' metaphor rather than just quoting it. It holds Birling's view and the Inspector's together in a single argument, which is exactly what a top-band answer does.
The structure a Grade 9 essay follows
Use a short thesis introduction, three or four body paragraphs each led by an idea and developed across the play, and a brief conclusion that returns to the argument, ideally with Priestley's purpose. Every paragraph should analyse a short quote and, where it helps, add a sentence of context.
Why good essays still lose marks
The commonest trap is retelling the plot instead of analysing it. The second is ignoring context, which in this play is half the meaning. The third is quoting long and analysing thin, when the top band wants short quotes read closely. Avoid those three and your knowledge will finally show as the grade it deserves.
