Calibration technicians execute calibration work. In large organizations, the work is further divided into three groups:

Alternatively, the technicians can be divided by major discipline areas: physical, dimensional, electrical, microwave and so on. But the principles are the same regardless of the equipment. Metrology technicians perform investigation work in addition to calibrations. They also apply proven principles to known situations and evaluate unexpected or contradictory results. Metrologists are people who perform metrology work at and above the technician levels.

The metrology and calibration work is always accompanied by documentation. The documentation can be divided into two types; one related to the task and the other related the administrative program. Task documentation includes calibration procedures and the data collected. Administrative program documentation includes equipment identification data, calibration certificates, calibration time interval information and 'as-found' or 'out-of-tolerance' notification. Administrative programs provide standardization of the metrology and calibration work and make it possible to independently verify that the work was performed. Generally, the administrative program is specific to the organization performing the work and addresses customer requirements. General administrative program specifications created by industry groups, such as the ANS (ANSI) Z540 series may also be covered in the administrative program. Other specifications created by the US Food and Drug Administration, US Federal Aviation Administration or other agencies would supplement or replace ANS Z540 for work performed in their domains. Often administrative programs can be as complicated and detailed as the measurement work itself.
