MAST now contains contributory factors (CFs) after the Department for Transport agreed to grant users access.
Contributory Factor definitions
Contributory factors definitions are set out in STATS20. There are clearly defined rules on what the contributory factors mean; which parties they are allowed to be attributed to; and in which circumstances they should be used. As some contributory factors can be seen in all three tabs in MAST, the names of the dimensions are also provided in the list on the Contributory factors definitions page.
