Advances in geothermal technologies and their usage created the need for a specific voluntary certification designation for geothermal drillers. NGWA responded to this need with the designation of Certified Vertical Closed Loop Driller (CVCLD).
The CVCLD is considered an independent designation from the CWD or CWD/PI. The designation reflects an individual who has passed a written exam administered by NGWA that evaluates an individual’s knowledge of the skills and competencies associated
with constructing a loop well.
NOTICE REGARDING TEST SITE CLOSURES EFFECTIVE MARCH 20, 2020
For the most up-to-date information about PSI test site closures, please see PSI’s website.
In the interest of care for exam candidates and staff, PSI has elected to temporarily close their PSI-owned and -operated sites in the United States from March 20, 2020 through at least April 13, 2020. Individuals who are scheduled within this timeframe
are being contacted by PSI to reschedule. Candidates may also reschedule themselves online without needing to contact the call center, using the information provided to them by email on registration. Given the circumstances, the rescheduling notice
period has been waived.
Third-party testing sites may remain open, at the discretion of the individual centers. If you have any concerns, please contact PSI or the center at which you are scheduled.
