Which criterion is about the ability to produce consistent results across tests and assessments?

• A. Reliable
• B. Measurable
• C. Time Constrained
• D. Attainable

Answer: (A)

Reliability is about producing consistent results across tests and assessments. When a measure is reliable, scores stay similar for the same person across repeated administrations under similar conditions, and different scorers tend to agree on the results. This consistency is what lets us trust that the measurement reflects the underlying quality or ability rather than random variation.

Measurable describes whether something can be quantified, but it doesn’t by itself address whether those measurements are stable across occasions. Time constrained focuses on how much time is available, not on score stability. Attainable concerns whether goals or outcomes are feasible, not on how consistently a test yields the same results.
