Dedicate one full body paragraph to each of the two distinct views presented in the question: one on punishment as rehabilitation and another on punishment as a deterrent. This structured approach ensures you address both sides thoroughly and avoid being perceived as too one-sided, which is crucial for a 'discuss both views' essay.

To strengthen your arguments, consider specific examples. For rehabilitation, you could mention restorative justice programs in countries like New Zealand or Norway, which focus on reintegration and reduced recidivism. For deterrence, discuss the strict penal codes in Singapore or the ongoing debate around capital punishment in some regions, highlighting their intended impact on potential offenders.

A common mistake on this question is failing to clearly differentiate between the two aims of punishment, often blending them or focusing disproportionately on one. To avoid this, use clear topic sentences for each body paragraph that explicitly state which view you are discussing, ensuring a balanced and well-structured argument.

Employ a clear linking strategy to guide the reader through your discussion. Start your second body paragraph with a phrase like 'Conversely, another school of thought posits that...' or 'While the aforementioned perspective focuses on individual reform, a different viewpoint emphasizes...' to signal the shift to the opposing argument.

For a band 8-9 answer, examiners look for a nuanced discussion that acknowledges the complexities of both views, supported by precise vocabulary related to criminology and justice (e.g., 'recidivism,' 'penal reform,' 'societal retribution,' 'general deterrence'). Your personal opinion in the conclusion should not simply choose one view but ideally offer a sophisticated synthesis or prioritize one aim with clear justification, demonstrating critical thinking.
