Two documents on this subject have been submitted for publication in the Bulletin. Document 1 is a statement of the circumstances which led to the setting up of a joint Working Party to consider these special requirements, and of the policy subsequently adopted by the College. Document 2 is the report of a survey conducted on behalf of the Working Party. It was found that there was some overlap between the two documents, and for this reason and for the convenience of readers some changes have been made in the presentation of their contents; in particular, some of the introductory passages of Document 2 have been transferred to Document 1, and for some passages which occur in both documents the reader is referred to Document 2.
