1.1 CST Certification & Survey Licensing Distinction

CST Certification & Survey Licensing Distinction

1. Purpose of the NSPS Certified Survey Technician Program

The National Society of Professional Surveyors (NSPS) established the Certified Survey Technician (CST) program to provide a recognized national career ladder and credentialing framework for survey crew members, instrument operators, party chiefs, and office technicians. Prior to the establishment of the CST program, survey technicians lacked a standardized, nationally portable credential that verified technical competence across state lines.

The CST program serves three primary objectives:

1. Career Advancement: Providing clear educational and operational benchmarks for technicians seeking professional development.
2. Quality Assurance: Assuring engineering firms, land surveying companies, and government agencies that certified staff possess verified technical skill sets.
3. Public Welfare: Elevating the overall quality of field data collection, boundary measurement, and mapping under the direction of licensed professionals.

2. The Four CST Certification Levels

The CST program is structured into four distinct levels, progressing from entry-level crew tasks to technical management. Experience requirements are based on full-time surveying employment (equivalent to 2,000 work hours per year).

Examination Rules for Level I

• Exam Structure: The Level I examination consists of 200 multiple-choice questions administered over a 4-hour testing window.
• Passing Score: Candidates must achieve a minimum score of 70% (answering at least 140 of 200 questions correctly).
• Open-Book Policy: The exam is open-book. Candidates may bring approved reference materials, including surveying handbooks, mathematical tables, and non-programmable or approved programmable scientific calculators (such as the HP 35s or TI-30Xa).

3. CST Certification vs. Professional Land Surveyor (PLS) State Licensure

Candidates preparing for the CST exam must thoroughly understand the critical legal distinction between technician certification and professional state licensure.

Technician Certification (CST)

• Issuer: Administered nationally by a private professional association (NSPS).
• Nature: A voluntary credential validating technical knowledge, mathematical ability, and instrument proficiency.
• Scope: CST credentials do not grant legal authority to practice land surveying independently. A CST cannot enter into contracts with the public to establish land boundaries, nor can a CST sign or seal survey plats.

Professional Land Surveyor (PLS) Licensure

• Issuer: Granted by individual State Boards of Licensure for Engineers and Surveyors under state statutory acts.
• Nature: A mandatory legal license required to practice land surveying within a given state jurisdiction.
• Scope: A licensed PLS holds exclusive legal authority to render legal opinions on property boundaries, sign and seal boundary survey maps, record subdivision plats, and assume statutory liability for survey work.

4. Legal Boundaries and Supervision Requirements

In all 50 U.S. states and territories, land surveying is a regulated profession restricted to licensed individuals. Under state licensing laws, a Certified Survey Technician must perform all surveying activities under the direct supervision and responsible charge of a licensed Professional Land Surveyor (PLS).

What "Responsible Charge" Means

Responsible charge refers to the direct control and personal supervision of engineering or land surveying work. The supervising PLS is legally required to review, verify, and approve all field data, mathematical computations, boundary determinations, and final drawings produced by survey technicians.

Exam Trap: A common CST exam trap asks whether a Level III or Level IV Certified Survey Technician can establish a property line independently if the client agrees. The answer is NO. Certification level does not alter statutory licensing requirements. Only a licensed PLS can legally establish property boundary lines.

Practical Application Example

A Level III CST Party Chief leads a field crew in performing a boundary retracement survey. The party chief locates existing iron pipes, measures angles and distances, and records field notes. Although the party chief makes field decisions regarding search radii and instrument setups, the final determination of property corner locations and the certification of the plat must be performed by the supervising PLS.
