IB Economics HL Internal Assessment Example

Relevant diagrams are included for each major economic issue discussed, showing clear intent to support the commentary visually.

The diagrams are generally connected to the policy mechanisms being analysed, such as shortages from a price ceiling and higher domestic prices under a tariff.

The student makes an effort to explain what the diagrams show rather than leaving them unexplained.

Some diagrams contain conceptual or labelling inaccuracies, especially where the market structure does not match the explanation being given.

Several labels are unclear or imprecise, which makes the diagrams harder to interpret and weakens their reliability.

A few diagrams and welfare areas are not fully accurate, so the visual evidence does not consistently support the analysis at a higher level.

The student uses a wide range of relevant economic terminology across the commentary.

Most of the key terms are generally applied in a way that fits the policy issue being discussed.

The terminology helps structure the discussion and show awareness of core economic ideas.

Some important terms are used imprecisely, especially where market names and mechanisms are confused.

A few claims blur distinctions that should remain separate, such as the difference between domestic and world prices in the tariff discussion.

The credibility of the analysis is weakened when terminology is not exact enough to match the diagram or causal chain.
