Membership does not have a capitalized, formal program name (unlike our trademarked products like the WELL Building Standard^TM and can be referred to in the following ways, depending on the nature of the sentence or formality of the correspondence:

• IWBI membership
• Membership at IWBI
• The IWBI member program 

Our member tiers, Keystone and Cornerstone, are formal, capitalized program components. Members should refer to their status as follows:

• [Company X] is a [Keystone, Cornerstone] member of the International WELL Building Institute^TM (IWBI^TM).
