There are no fixed standards. It varies from company to company. In my experience, the average training days for employees were as follows at the place where I worked:
Training Days by Employee Level
Level 1: Executive and Sr. Executive - 6 days/year
Level 2: TL and AM - 8 days/year
Level 3: Managers and Sr. Managers - 8 days/year
Level 4: AVP and VP - 8 days/year
These days were determined after a complete Training Needs Identification (TNI) based on the competency mapping process.
