Tiefentest

Tiefentest is a German-language term that literally means "deep test." It is used in several fields to describe an assessment approach that aims to probe deeper aspects of a subject than standard tests. Because the term is not standardized, its exact meaning depends on the domain.

In software testing, Tiefentest is often used informally to describe tests that go beyond functional checks and examine internal structures, interactions between components, and long-term behavior under stress or unexpected conditions. In education and psychology, it refers to assessments designed to measure deep understanding, transfer of knowledge, problem-solving ability, and critical thinking, rather than surface-level recall. In research and evaluation, Tiefentest may denote extended, multi-method evaluations conducted over multiple tasks or settings to reveal underlying competencies or processes.

Typical characteristics include focusing on core concepts, requiring integration of knowledge, longer administration time, and the use of multiple data sources. Methods may involve scenario-based tasks, project work, performance assessments, think-aloud protocols, and longitudinal observation. Validity and reliability are essential, with explicit scoring rubrics and peer or expert review to minimize bias.

Advantages include richer information about mastery and processes; disadvantages include higher cost, complexity, and potential difficulties in standardization and comparison across contexts. Because the term lacks a single, universal definition, practitioners should specify the scope, methods, and criteria when using Tiefentest.
