Marks for criterion B should be awarded as follows:
- 1-2 General knowledge of topic (promotion of health)

- 5-6 Relevant knowledge of specific research methods material is utilized and concepts are defined within the context of the specific study.
Marks awarded for criterion C assess the quality of the description of a study/studies and assess how well the candidate linked aspects of the study to the question.
Candidates may discuss one research method in order to demonstrate depth of knowledge, or may discuss a larger number of research methods in order to demonstrate breadth of knowledge. Both approaches are equally acceptable.
For studies where there may be more than one research method, candidates should not be penalized for discussing one of the research methods other than the main research method.
