Representational Competence of Fields Inventory (RCFI)


The Representational Competence of Fields Inventory (RCFI) aims to assess and facilitate the comprehension of diagrams, graphs, and mathematical equations within the context of undergraduate physics curricula, specifically focusing on vector fields.


The RCFI is typically given to students in their third semester pursuing studies in science, physics, technology, engineering, and mathematics disciplines.

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 MSES-R primarily concentrates on college students, encompassing those studying physics, mathematics, and engineering. Items were examined for discrimination, and assessment reliability. Relevant articles are listed below:

      Küchemann, S., Malone, S., Edelsbrunner, P., Lichtenberger, A., Stern, E., Schumacher, R., … & Kuhn, J. (2021). Inventory for the assessment of representational competence of vector fields. Physical Review Physics Education Research, 17(2), 020126.


We recommend using Google Scholar and the citations listed under validation to find articles of interest.
