Stucco Inspector Questions

Good morning. I have been a masonry contractor for 30 years in the Metropolitan Pennsylvania area and have interest in becoming a Certified Stucco Inspector. I am not planning on becoming a Home Inspector so I am not sure if it is a requirement that I must first become a home inspector in order to become a member of your organization in order to take the Accredited Stucco training course currently being offered. Your guidance and direction is most appreciated. Thank you in advance. Michael Angelo Masonry,LTD.
