In 2014, LearnCST was established to promote the National Society of Surveyors Certified Survey Technician (CST) program and offer a robust eLearning tool for those pondering certification. Ultimately, certification creates common ground for employers and those they employ. It also creates an inbound path for those pondering a career in land surveying.

Since 1988, the CST

program has certified thousands of technicians across the United States. During that time, the land surveying profession has evolved considerably as a result of technological innovation. In the midst of so much change, it has become harder and harder for employers to determine whether a survey technician is versed in the “old” ways or the “new”; those with wide experience are in short supply.

CST offers four levels of certification with specialty focuses upon arrival at level II:

  • Level I technicians are required to demonstrate knowledge of basic skills
  • Level II technicians must have 1.5 years experience or 65 semester hours
  • Level III technicians must have 3.5 years experience or 65 semester hours
  • Level IV technicians must complete a custom essay-based submission
