NMQA will provide you with all relevant changes that should be implemented, considered or tested to ensure compliance. When this work is completed and your site becomes live, or can be accessed by W3C’s automated validation tools, we recommend executing the validation against your website.
Your compliance level will then be shown to you by the W3C, and the relevant certification logo displayed can be placed on your website.
N.B. Your compliance level can vary based upon updates to your website, and technologies used. It is necessary to retest your site or implement development conformance procedures to keep your certification level current.
