IB Economics SL Internal Assessment Example

The student included two relevant diagrams that were clearly connected to the housing policies in the article.

The price-ceiling diagram was generally accurate, correctly labelled, and clearly linked to the resulting shortage.

The student's explanation of the price-ceiling diagram showed a solid understanding of how intervention affects rents and incentives.

The tax diagram did not accurately match the policy being discussed.

The relationship between the diagram and the student's written explanation was inconsistent, especially about how the tax would increase land availability.

A clearer explanation of who pays the tax and how that changes behaviour would improve the diagram.

The student uses a wide range of relevant economic terms such as price ceiling, equilibrium, shortage, tax, subsidy, and elasticity.

The student's language generally keeps the commentary anchored in microeconomic analysis rather than description alone.

Some terms are not used precisely enough for the policy the student is analysing.

The student's discussion of tax and elasticity would be stronger if the terminology matched the exact policy mechanism more carefully.

A few claims are technically correct in isolation but not fully integrated into the argument.
