What is the purpose of the TSA CBT's time limit?

The purpose of the TSA CBT's time limit is to maintain a standard testing duration. A consistent time frame ensures that all candidates are evaluated under the same conditions, which is crucial for fairness and comparability of scores. This standardization helps to eliminate variability that could arise from different testing durations, allowing for a more accurate assessment of a candidate's abilities and potential.

While other factors such as stress, breaks, and the balance between speed and accuracy might be considerations in test design, the primary objective of a time limit is to create a uniform experience for all test takers, which ultimately leads to a more equitable evaluation process. This standardization is important in the context of assessment validity and reliability.
