While we are happy to share some of the criteria we do not share it all, as doing would so would dilute the value of the Certification by making it easy for some to overstate their company’s statistics or include inaccurate figures. We do however list the minimum requirements so applicants can be prepared for what will be required (read them by clicking here). Bear in mind, while any Custom Installation (CI) firm may apply for HTA Certification we estimate less than 15% of CI firms will meet the HTA’s stringent criteria. Our goal is to ensure only the best firms may achieve HTA Certification.
