The Coordinate Metrology Society (CMS) has established a relationship with the American Society of Photogrammetry and Remote Sensing (ASPRS) for the purpose of administering professional certification in Portable 3D Metrology. The ASPRS Articles of Incorporation state that it will exert its influence towards the betterment of standards and ethics.


To this end the ASPRS Professional Activities Committee after several years of careful study developed a program for certification of photogrammetrists. This program was approved by the American Society of Photogrammetry (ASP) Board of Direction at its meeting in Washington D.C. on March 13 1975. On March 28 1991 the ASPRS Board of Directors approved a proposal made by the National Photogrammetrist Recognition Committee of the Professional Practice Division to modify the original program to include two new categories of certification: Mapping Scientist Remote Sensing; and Mapping Scientist GIS/LIS. The Board approved a recertification program that assures that certified persons keep up with the technology that is rapidly changing. The Board on October 28 1997 approved a modification to the program adding a requirement of a written examination effective January 1 1998. On October 29 2012 the ASPRS Board of Directors approved the addition of administering a certification program to support the CMS’s portable metrology community to the ASPRS Certification Program activities.


There is a distinction between certification and licensure. Simply stated CMS/ASPRS certification is official recognition by one’s colleagues and peers that an individual has demonstrated professional integrity and competence in their field. As such the CMS/ASPRS voluntary certification program is considered “specialty certification.” It is not a substitute for licensure as for example a Land Surveyor. Licensure is a legal act on the part of states to protect the public health safety and welfare. It is a procedure by which various state and local governments require the licensing of certain professions practices trades etc. under formal statutes and ordinances to protect the well-being of its citizens. Licensure may be required by your local state county etc. whether or not you secure certification.

The CMS Certification program as approved is entirely voluntary. In accordance with the CMS Code of Ethics persons certified should decline to undertake any work within or related to the fields of metrology that is outside their range of competence.

Information on how to apply for certification requirements educational credits and administrative review procedures are outlined below.


A growing number of scientific and technical disciplines depend on portable 3D metrology for reliable measurements and information. It is in the interest of those who provide portable 3D metrology services as well as the user of these services that such information and data be accurate and dependable. The CMS/ASPRS Certification Program has as its purpose the establishment and maintenance of high standards of ethical conduct and professional practice among portable 3D metrologists.

The primary objectives of the programs are:

  1. To identify and recognize those persons who after careful just appraisal by their peers and after passing a written examination are considered to have met the requirements established by the Society for certification.

  2. To provide a basis for weighing the validity or allegations and complaints that involve practicing portable 3D metrologists and for taking appropriate action in connection therewith.

  3. To encourage persons as yet not fully qualified to work towards certification as a goal of professional achievement.

  4. To encourage certified persons through the recertification process to continue their professional achievements as rapid changes in technology occur.

The CMS/ASPRS Certification Program is voluntary and open to all qualified individuals whether or not they are members of the Coordinate Metrology Society or the American Society for Photogrammetry and Remote Sensing.


In view of the wide variety of skills and disciplines studied and practiced by portable 3D metrologists the CMS/ASPRS Certification Program is based primarily on evidence of demonstrated professional capability. Within prescribed limitations it does permit experience to be substituted for education and vice versa and requires a written examination. Following are basic requirements for:

Certified Portable 3D Metrologist Level 1 (CMS)
A professional who uses portable 3D metrology technology to collect measurements and interpret data from a variety of contact and non-contact portable 3D measurement devices. The Portable 3D Metrologist is responsible for all phases of data collection and other mensuration requirements which include planning and supervising survey activities requirements and interpretation.

  1. Two years of experience in portable 3D metrology one year of which was in a position of professional responsibility demonstrating professional knowledge and competence.

  2. References from three persons who are holding or who have held responsible positions in portable 3D metrology and have first-hand knowledge of the applicant’s professional and personal qualifications.

  3. Declaration of compliance with the Code of Ethics of the CMS.

  4. Successful completion of a written examination.

Certified Portable Metrologist Level 2 (CMS)

  1. Hold a current Level 1 certification
  2. Two years of hands-on practical experience and a minimum of 400 hundred hours use with the requisite device (PCMM Laser Tracker etc.)
  3. Two references
  4. Successful completion of a practical (hands-on) examination.

Note: Level 2 certifications expire on same date as Level 1.


When computing the number of years of experience under basic requirements credit may be taken in lieu of actual job experience for degrees in engineering or in the natural or physical sciences on the following basis:

Type of Degree Years of Credit
Bachelor’s 1/2
Master’s 1/2


Anyone who has been certified by the CMS/ASPRS is certified for life unless there is cause to remove the certification for malpractice or violation of the Code of Ethics of CMS. The Society has a Recertification Program to assure that a certified person has maintained or improved on those skills and knowledge that allowed for certification. The Society will maintain an ACTIVE CERTIFICATION LIST that requires recertification every five years. Certified persons will appear on the Active Certified list for as long as their certification is in force.

Recertification applicants are required to fill out the Recertification application (not yet available) to show the type of activity that they have practiced and their professional involvement in portable 3D metrology.


Recertification is based upon a “Continued Professional Development Qualification” rating system of Professional Development Hours (PDH) of credit. Recertification applicants are required to fill out the Recertification Application to show the type and duration of activity that they have practiced and their professional involvement in portable 3D metrology. They must also have three References who have knowledge of the applicant’s professional and personal involvement in the LAST FIVE (5) YEARS. Each applicant must have completed and documented 75 Professional Development Hours (PDH) or PDH Credits based on the following criteria which will be evaluated by the Certification Committee.

*NOTE: you may also choose to recertify by exam every five years in lieu of recertifying by PDH hours.

 Level 2

1000 hours of use of Requisite device (PCMM Laser Tracker etc) over the past 5 years.

Note: Number of hours required will be pro-rated by-month for the first 5 year certification cycle.

Example (Level 1 obtained July 1 2014 Level 2 obtained July 1 2015 only 816 hours of documented device use is needed to recertify on July 1 2019)



Certified Professionals who do not become recertified are automatically placed in either an Inactive or Retired status. Individuals in either category are not permitted to use their seal to sign plans or otherwise indicate in any way that they are active Certified Professionals. An online searchable list of all active Certified Professionals in each category is maintained.

Individuals whose Certified status is Inactive or Retired for a period longer than one (1) year following Active status may apply for recertification provided that in addition to the standard recertification criteria (outlined above) they take and pass the examination in their respective certification area.


An embossing seal and rubber stamp which contains the name and certification number may be ordered (TBA) from ASPRS. There is a nominal fee for each.

Certification and recertification are for individuals only. The designation of “Certified” may not be used in such a manner as to indicate that a business firm or agency is certified as an entity.

The use of a seal or stamp is not authorized for those individuals holding the Certification status of “Provisional” or by those whose status has become “Inactive” or “Retired.”

Note: CMS certification seals and stamps can only be authorized by CMS/ASPRS and manufactured by ASPRS-approved vendors. Unauthorized seal or stamp production is a violation of copyright law and the Code of Ethics.


The Society reserves the right to change or amend the requirements for certification and recertification the educational credits or the administrative fee structure for review and evaluation if and when deemed appropriate by the Executive Committee.

The Society further reserves the right to revoke a certification or recertification if in the opinion of the Executive Committee the person concerned has violated or shown flagrant disregard for the Code of Ethics of the Society.

Since the program is entirely voluntary the Society assumes no responsibility for any loss or disadvantage real or imagined which may be alleged to have resulted from a disapproval of an application for certification recertification or revocation of the certificate once given.

By submitting their application the applicant acknowledges that the Society will apply the internal standards adopted by its Executive Committee in evaluating the applicant and that it may reject any applicant who does not meet its minimum standards for certification or recertification. In consideration of CMS/ASPRS acceptance and processing of an application the applicant agrees to waive any and all claims of liability or responsibility against CMS/ASPRS and to indemnify and hold harmless CMS/ASPRS its directors officers committee members employees agents and representatives against any and all such injury damages or claims made by or on behalf of any person partnership association or corporation. Applicant further acknowledges that CMS/ASPRS its directors officers committee members employees agents or representatives are not liable to the applicant or to any other person partnership association or corporation in any way for any injury damages or claims alleged to be based upon or arising out of the approval or disapproval or the issuance withdrawal or termination of any certification or recertification issued by CMS/ASPRS.
