This paper presents an overview of several sources for codes of conduct and quality assurance in online surveys. The first section introduces general codes of conducts, as these also apply in online surveys. The second section outlines guides focusing on ethical issues. Ethical standards are especially important in online surveys, due to new (often technical) issues concerning privacy, data security and sampling. The third section gives a general idea of quality assurance in online surveys. In that special field, some branches developed rapidly. This caused the formation of specialized guides: online survey software, access panels, and employee surveys.
