What term is used to describe a test question that is open to interpretation and could vary based on who is scoring it?

The term used to describe a test question that is open to interpretation and could vary based on who is scoring it is "subjective." Subjective questions often allow for personal judgment and opinions in the evaluation process, meaning different evaluators might arrive at different conclusions based on their perspectives. This contrasts with objective questions, which have clear and definitive answers that do not depend on personal interpretation. In subjective assessments, factors like the scorer's experiences, biases, and understanding can significantly influence the outcome, making these types of questions more flexible, yet potentially less consistent in terms of scoring. Subjectivity in testing can be both a strength, allowing for nuanced and deeper evaluation of complex ideas, and a challenge, due to the variability it introduces in the assessment process.
