Testothek

Testothek is a term used to describe a curated repository of tests and test-related resources. Originating from the German word Test and the suffix -othek, analogous to library, a Testothek functions as a centralized collection to facilitate the sharing, reuse, and evaluation of test materials across institutions and disciplines. In practice, a Testothek may be hosted by universities, research centers, professional associations, or software quality groups, and can be physical or digital.

Contents typically include item banks for examinations, psychometric instruments, scoring rubrics, validation studies, guidelines on administration, as well as test data sets, sample code, and automation scripts. Each item or resource is usually described with metadata such as subject area, difficulty, cognitive level, licensing, usage restrictions, author, and version history. Access policies vary; some Testotheken are open access, others require credentials or institutional affiliation.

Governance and quality assurance are common features: editorial boards, peer review or item review processes, standards for reliability and validity, and mechanisms for updating or retiring items. Licensing may range from Creative Commons to proprietary arrangements, with clear attribution and citation requirements. Ethical considerations include privacy, informed consent for data, and the avoidance of misuse or bias in test content.

Impact and use cases include educational assessment, research on testing methods, and software quality assurance through shared test suites. By enabling reuse and benchmarking, Testotheken aim to reduce duplication of effort and improve comparability across studies or products.
