Graphics Concept Inventory (GCI)


The Graphics Concept Inventory (GCI), also referred to as the Engineering Graphics Concept Inventory (EGCI), is frequently employed to recognize misunderstandings and proficiencies within the realm of engineering graphics.


GCI is frequently utilized as an assessment tool in engineering courses in first year and second year.

Typical Performance

We do not know of any published results with typical performance. As the LASSO platform collects more data, we will be able to offer better guidance on student performance.


The GCI has been administered to college students, and assessments were reviewed by education research graduates and authors. Relevant articles are listed below:

RCDI has been administered to college chemistry students, and valid data supported by relevant articles listed below:
