Abstract: | Motivating students to perform well on assessment tests is difficult when students know the results have no academic consequence. The present study evaluates the influence of assessment context (graded vs. non-graded) on the reliability of an assessment measure. Results indicate the graded condition produces higher reliability (r= .71) than the non-graded condition (r = .29), which leads to unacceptably low reliability. Moreover, the graded condition produces significantly higher scores (M = 64%), than the non-graded condition (M = 43%). Only students in the graded condition (41%) obtained passing scores of 70% or above. |
