The annual summaries are the result of the REG annual assessment of each Road Controlling Authority's (RCA) One Network Road Classification (ONRC) performance measure and asset management data.
Each spreadsheet summarises the reported annual high-level results for a RCA based on an evolving data quality framework of metrics interrogating data for a range of data quality dimensions including completeness, accuracy and timeliness.

|2017/18 [XLSM, 125 KB]||The 2018/19 data quality assessment based on 63 metrics; 32 ONRC metrics and 31 asset management metrics.|
This is produced by summarising the individual RCA metric results generated within the PMRT. PMRT is the only place where the metric level of detail is available to each RCA.
The overview Understanding the data quality results provides a detailed level of support and direction in understanding the results.
