Confidentiality

It is customary to identify confidentiality as a property of information that is obtained on an identifiable individual or an entity. In education research, the information may take the form of a written hard document or digitized record, a video or audio recording, or an oral report on an observation from the researcher’s memory. A confidentiality assurance to an individual or an entity entails a promise that, to the extent possible, the information on identifiable individuals or entities will not be disclosed outside the research context in which it is generated and for which it is used. Such an assurance is common in many social research sectors, including education. This entry further defines confidentiality and discusses how it relates to public information, private information, and professional codes of ethics. It then looks at approaches that reduce or obviate the need for confidentiality and the relationship of confidentiality to research that involves linking records over time or linking records from multiple sources.

Confidentiality is distinguished from and related to privacy, which is a property of the individual on whom information is obtained. One may assure an individual or a group that whatever information they provide will remain confidential, though the information’s provision can be construed in a narrow sense as a reduction in privacy. Assurance then constitutes a limit on any further reduction of privacy.

Security is distinguishable from both confidentiality and privacy. It usually refers to the conditions under which information is maintained and used. Physical locks and electronic encryption schemes are examples of security measures.

Public Versus Private Information

At one extreme, much information on identifiable individuals is public. In the United States, for instance, administrative records on public school teachers are collected and maintained by state education agencies. That information—on teacher identity, teaching or administrative assignments, and other data—is, at times, publicly accessible on state data systems websites and is used in education research. In such records, and in other public systems on parole officers or nurses or others employed by government, salaries and other information on individuals are disclosed.

At the other extreme, law and regulation can restrict access to information and, in doing so, actualize an assurance of confidentiality. For example, records on students in education institutions, whether the institutions are public or private, are covered in the United States by the Family Educational Rights and Privacy Act. Such records cannot be disclosed to anyone who is not associated with the school unless certain conditions are met. One such condition involves asking the students to agree in advance to the disclosure of their records for research purposes, as is the case for some massive online open-access course data systems.

Between these two extremes, there is considerable variation in the factors that influence, or are influenced by, assurances of confidentiality. The World Wide Web, generally, and social media initiatives, in particular, engender far more complicated issues.

Professional Codes of Ethics and Confidentiality

Many professional associations have developed codes of ethics that attend to confidentiality in the context of educational and social research. Section 12 of the American Educational Research Association Code of Ethics published in 2011, for instance, considers the topic in detail. Among other things, it tells its members that “confidential information is protected,” that “educational researchers take reasonable precautions to protect the confidentiality of information related to research participants… . (and) do not allow information gained in confidence to be used in ways would unfairly compromise research participants, students, employees, clients, or others” (p. 149). Other organizations that have addressed confidentiality issues, and to which education research is at times relevant, include the American Psychological Association, American Criminological Society, and American Sociological Association.
