This project systematically develops, validates, and analyzes psychological and educational assessments with a focus on scale reliability and validity. The workflow proceeds in two phases: (1) Questionnaire Development & Validation and (2) Classical Test Theory Analysis. Together, these phases ensure that the scale is statistically sound, measures the intended construct accurately, and is broadly applicable across psychology, education, and the social sciences.
