Certificates of Technical Excellence. TVNI provides two types of certificates that recognize individual or company expertise in various applications of the Vetiver
System. Details about this certification, lists of those certified, and an application form are at a completely revamped and simplified page that can be found HERE. Those applying for certification should read the guidelines carefully. Note the two different levels of certification. Professional Certification is for those applying for certification in bioengineering and phytoremedial applications, where detailed engineering and water related knowledge is required, and where there is potential risk, if applied by people with limited knowledge. A general Certificate of Technical Excellence is awarded to applicants who can show that they have good knowledge of various applications and can show successful results in most other applications other than those applying for Professional Certification.
