Checkable

Checkable is an adjective meaning capable of being checked, inspected, verified, or tested. The term is used across disciplines to describe statements, conditions, or objects for which evidence or evaluation is possible.

In information quality and journalism, a claim is described as checkable when there exists a method or corpus of data by which it can be confirmed or refuted. Checkability underpins fact-checking, scholarly scrutiny, and transparent communication.

In philosophy and science, checkable propositions are those that can be tested or falsified through observation or experiment. Checkability supports empirical inquiry, but does not by itself guarantee truth; it enables assessment and replication.

In computing and data systems, a condition or input is checkable if a program can determine whether it satisfies required criteria. Checkable properties are evaluated by tests or runtime assertions, and are central to validation, error handling, and quality assurance.

In user interfaces, elements that can be toggled or selected, such as checkboxes, are described as checkable. The concept also extends to workflows and process controls, where checkable steps allow verification of completion or conformity.
