The Hydrologic Technician has an emphasis on hands-on knowledge and field experience. The certification is conferred by AIH on professionals who demonstrate, through an application submitted to AIH, that they meet the minimum education, personal integrity, and experience requirements and have passed the appropriate examination(s) administered by AIH. Once certified, certified Hydrologic Technicians may represent themselves as HT I, HT II, or HT III reflecting their level of certification.
