Commanders and organization leaders establish unit rating schemes. AR 623-3 paragraph 2-2a states:
Fundamentals: Commanders, commandants, and organization leaders will establish rating chains and publish rating schemes within their units or organizations in accordance with locally developed procedures and ARs. Rating schemes for two-star level commands (or equivalent organizations) and below will be approved by the next higher commander, commandant, or organizational leader. Established rating chains will correspond as nearly as practicable to the chain of command or supervision within a unit or organization, regardless of component or geographical location. Rating schemes will identify the name of the rated Soldier and the effective date for each of the rating officials (date on which the rating official assumed their role as the rating official for the rated Soldier). Rating schemes will be published and made accessible, either manually or electronically, to each rated Soldier and each member of the rating chain. Any changes to a rating scheme will be published and distributed, as required. No changes may be retroactive.
While the commander is responsible for the rating scheme the regulation does allow for the First Sergeant (Organization Leaders), to provide input. As long as the requirements of the regulation is followed in establishing the rating chain and the commander approves of the First Sergeant’s recommendations, his input would be appropriate.
