Individual gradings can be found at National Grading Scheme.  To find somebody's grading you can type the surname into "search" and then hit the "enter" button on your computer. 

This may not work with Internet Explorer 9 but works with other browsers.  With IE9 you can make it work by clicking on "tools" and then "compatibility view".  

Information on how the grading scheme works can be found from the right hand side of the above page.
