(b)Reports should be recorded in the prescribed forms. The gradation number of the officer given in the latest edition of the Civil list, the post held by him, and in case he held more than one post during the reporting year, the exact period (with dates) during which he held particular post must be mentioned clearly and accurately. The report should invariably give the name and designation of the reporting officer also. Reports should be based on the personal knowledge. The report for a particular year should not take into account the work and conduct of the officer reported on a previous year, or at a different station. Where a report is not based on direct personal knowledge but on some other officers estimate, such as note left by the predecessor, or on matters which come to light during inspection of an officer's work after his transfer, the fact should be mentioned.
