The Postal Service strongly disagrees with the conclusion that our current service performance measurement is not accurate. We use the expertise of a highly reputable firm with long-standing proficiency in the design and execution of measurement systems that yield results that are statistically valid and reliable.

The Postal Service is strongly committed to transparency and the regular publication of our service performance results, including those in rural areas through a rural service measurement initiative. We continue to work with Congress and our regulator to develop enhanced methods for evaluating delivery performance that are already robust and accurate.
