In arts and health evaluation practice, ethical best practice relates to three main areas: respect for individuals; social responsibility; and, the maximising of benefit and minimising of harm. We ensure that our responsibilities in these areas are met through mechanisms such as having an informed consent process when collecting data, respecting people’s need for confidentiality and anonymity, considering potential risks to participants in an evaluation and ensuring that no individual or group is stigmatised or mis-represented through it.  Unless you are conducting research, you are unlikely to need to go through a formal ethical approval process and therefore there is no single set of formal rules to adhere to, but specific ethical considerations will apply to particular data collection methods.
