This study quantified student responses between two different versions (1 and 3) of the Biomechanics Concept Inventory (BCI) assessment. Fifty students from a comprehensive university in the USA took both BCI versions on the first (pre) and last (post) day of an introductory undergraduate biomechanics course. Students scored significantly higher on BCI 3 for the post-test and gain score (i.e.: difference between pre and post). Eight of the twelve competency areas resulted in significantly different correct scores between versions. Correlations of competencies between versions ranged from -0.13 to 0.43, however, only two were significant. Discriminant analysis of the competency areas determined that BCI 1 predicted overall assessment performance better than BCI 3. The disparate results between versions should be considered in determining which to use.
