The complexities of the ethics and truth in archival research are often unrecognised or invisible in educational research. This paper complicates the process of collecting data in the archives, as it problematises notions of ethics and truth in the archives. The archival research took place in the former Czechoslovakia and its turbulent political history influenced the way data were accessed and collected. The article analyses the productive power of archival institutions and their guardians, and examines the ethical dilemma of discovering sensitive information. Archival institutions hold the secrets that, once uncovered, can have powerful ramifications. It will be argued that the nature of truth in the archives is complex, and the author complicates and challenges the perception that archives are ethically neutral research spaces that do not need to consider approval from research ethics committees.
