Hi,
In normal your immediate Superior (HR Manager or above) is supposed to evaluate your performance for the period under review. However if your job role involves co-ordination with all department heads in terms of HR related tasks, the opinion of other department heads can be sought like how far you are addressing and clearing their queries/requirement within the stipulated time frame. However final approval process is purely your immediate Supervisor/dept head's call.
