Credential: Industrial Hydraulic Technician (IHT)  GI Bill resource
Credentialing Agency: International Fluid Power Society (IFPS)

Renewal Period: 5 years

The International Fluid Power Society (IFPS), Industrial Hydraulic Technician (IHT) certification is for professionals in the fluid power and motion control industry who test, troubleshoot, modify systems, and prepare reports. Applying fluid power theory and related knowledge, IHTs test and troubleshoot operational industrial hydraulic systems and applications. In addition, IHTs read industrial application schematics, perform basic cylinder and hydraulic motor calculations, and supervise system installations and commissioning. Candidates must pass a written and a job performance exam.
