The purpose of this article is to describe and analyze the psychometric properties of the Learning Orientation Questionnaire (LOQ), which have not been previously published. Psychometric validation involves the accumulation of proper empirical evidence to confirm measurement of the intended construct, and to justify the intended uses of the scales. LOQ is based upon the intentional learning theory, which is a comprehensive, holistic learning theory. Through the expertise of the LOQ's developer, educational researcher, and psychometrician, this article presents evidence of LOQ's reliability and validity according to published best practices for scale development and validation. LOQ is a reliable and valid instrument determining where learners fall along the learning orientation continuum. Education researchers can use this information to support learners to move upward on the learning orientation continuum, improving their inclination to learn, high-order thinking, and life-long learning.
