The diploma was first awarded in 1922 and surveyors with the diploma are entitled to the additional designatory letters Dip. Rating. Since its inception the diploma has involved a course of study though this is now tested by a series of assignments rather than traditional style examinations.
This website provides details and links to the study course but also provides a resource for diploma holders as well as visitors to the site.
The Rating Diploma Holders’ Section is the section of the Royal Institution of Chartered Surveyors for holders of the Rating Diploma. The Section dates from 1922.
