Early exposure to engineering has been found to help students in their decision-making regarding engineering educationand career pathways. Subsequently, an NSF-funded project is underway that is focused on development of an engineeringcurriculum for students in grades six through nine. The Engineering Design Process (EDP) frames this curriculum. Thecurrent study presents the validation methods and results of a multiple-choice assessment created to measure students’understanding of the EDP. The utilization of Think Aloud Interviews and the application and analysis of qualitativecoding schemes for the purpose of systematically gathering evidence about the psychometric quality of the assessment aredescribed. Findings from this study support the validity of the EDP assessment through evidence of alignment between theintended skills and the skills elicited in the student interviews.
