SCANNER Quality Score

What is quality scoring?

At the start of the 2014/15 survey year it was proposed that a quality score system be introduced for SCANNER to provide an objective measure of the level to which contractors are delivering the requirements of the SCANNER Quality Assurance process defined in volume 4 of the SCANNER specification SCANNER surveys for Local Roads User Guide and Specification Volume 4: Technical Requirements for SCANNER Survey Data and Quality Assurance 2011

It should be noted that the Quality Score is solely a measurement of the level to which the SCANNER contractor has met the delivery and monitoring requirements of the QA process:

• The SCANNER quality score does not reflect or indicate the ability of a contractor to deliver SCANNER surveys.
• The SCANNER quality score does not provide an assessment of the accuracy or consistency of the data provided by any particular contractor.
• The SCANNER quality score does reflect the current level to which a contractor meets the formal QA process requirements of SCANNER.

The quality score process was run on a trial basis during 2014/15 survey to obtain an understanding of the behaviour of the measure, and is being published to stakeholders from the start of the 2015/16 survey year.

What are the current SCANNER quality scores?

The table below shows the quality score achieved by the current survey contractors operating accredited SCANNER devices  for the current and previous survey years.
