Sample essay

Climate Policy Argument Essay

Use the class rubric to evaluate an argumentative essay on whether cities should expand low-emission zones.

Low-emission zones can reduce pollution, but they must be paired with public transit discounts so the policy does not punish workers who cannot immediately replace their cars.

Illustrative output example

Overall score: Proficient

The draft has a clear claim and a practical policy lens. The rubric fit is strongest for argument focus and organization, while evidence quality needs more specific sources and explanation.

This synthetic example demonstrates the report format. It is not a validation result or a substitute for teacher judgment.

Strengths
  • States a defensible claim that matches the assignment focus
  • Uses a balanced policy recommendation instead of a one-sided answer
  • Organizes the argument around tradeoffs and implementation
Improvements
  • Add concrete evidence from class sources or city case studies
  • Explain how the policy would affect different stakeholder groups
  • Tie the conclusion back to the rubric's reasoning criterion
