How long is the Bayley assessment?

• A. 1 hour
• B. 30 minutes
• C. 2 hours
• D. 45 minutes

Answer: (A)

The main idea is knowing how long the Bayley scales typically take to administer. The core administration is designed to be completed in about 60 minutes. Depending on the child’s age and cooperation, some sessions may run a bit longer, especially if you also include caregiver questionnaires, which can bring the total to about 90 minutes. The shorter times would not allow enough items to be reliably administered, while the much longer time isn’t the standard administration duration. So, the best answer is roughly one hour.
