How can bias impact assessments?

Bias in assessments can significantly skew results and lead to unfair disadvantages for certain groups of students. This occurs because assessments may not adequately account for differences in cultural background, language proficiency, learning styles, or socioeconomic factors. When biases influence how questions are framed, which content is included, or how responses are interpreted, they can produce outcomes that do not truly reflect a student's knowledge or abilities.

For instance, if assessment items are culturally biased, students from diverse backgrounds may struggle to grasp the questions, not due to a lack of understanding of the content but rather due to unfamiliarity with the context presented. This unfairly impacts their performance and does not provide an accurate picture of their capabilities. As a result, recognizing and addressing bias in assessments is crucial to ensure that all students are evaluated fairly and equitably, which is essential for accurate measurement of student learning and achievement.
