We are an open project to create a free, community-driven collection of test questions for measuring learner proficiency in every subject area across the entirety of human knowledge. The questions are all organized around a community-defined set of concepts, in order to enable a model of learning measurement that is continuous and context-agnostic.
Continuous means that measurements are taken before, during and after the learning experience. Continuous learning measurement favors small frequent measurement over large episodic measurement.
Context-agnostic means that the measurements produced must be relevant in any learning context--in or out of a classroom, instructor-led or self-directed. Context-agnostic metrics enable a lingua franca of learning measurement: a common language for measuring expertise in any subject, regardless of the type of learner or educational institution.
