PURPOSE AND RATIONALE OF THE QUALIFICATION 
Purpose:

The basis for Metrology is being able to ensure that all measurements undertaken are in compliance with international standards of measurement. This entails calibration of all types of measurement equipment. Learners achieving this qualification will be able to perform measurements that are confirmed against national measuring standards. They will also be able to maintain laboratory standard measurement artefacts, generate new standard measurement artefacts and calibrate laboratory equipment.

Learners will be able to:
  • Solve measurement and metrology problems.
  • Communicate Metrology information in the workplace.
  • Demonstrate understanding of Metrology principles.
  • Initiate and control a test or calibration laboratory.

    And one of the following outcomes, depending on the specialisation category selected:
  • Perform Electrical measurements and calibrations.
  • Perform Temperature measurements and calibrations.
  • Perform Mass measurements and calibrations.
  • Perform Dimensional measurements and calibrations.
  • Perform Force Torque and Hardness measurements and calibrations.
  • Perform Radio Frequency measurements and calibrations.
  • Perform Time & Frequency measurements and calibrations.
  • Perform Pressure measurements and calibrations.
  • Perform Humidity measurements and calibrations.
  • Perform Flow measurements and calibrations.
  • Perform Legal Metrology measurements and calibrations.
  • Perform Optical Radiometry measurements and calibrations.
  • Perform Fibre Optical measurements and calibrations.
  • Perform Ionizing Radiation measurements and calibrations.

    Performing measurement and calibration is critically important to the entire engineering industry and learners at the level of this qualification will take full responsibility for ensuring the correctness of measurements that may be used in industry, taking cognisance of varying factors in the operation of measuring equipment.

    Rationale:

    Metrology may be defined as "the science of ensuring the equivalence of measurement in order to improve the quality of life". This implies that inaccurate measurements will have a direct negative effect on the quality of life for all citizens of South Africa. This Qualification reflects the workplace-based needs of measurements in Industry as expressed by stakeholders and provides the learner with accessibility to employment opportunities within the Metrology Industry.

    Measurement is used in all engineering disciplines and Metrology comprises a wide variety of applications in which measurement must be ensured. This qualification provides the learner with flexibility to articulate in the measurement environment through selecting one of the specialisation options, and further articulation within the Engineering Sector.

    The competencies identified within the range of electives will allow the individual to pursue a career as a specialist Metrologist in the selected category. The competencies achieved from each of the elective categories will serve as foundational knowledge and skills relevant to the other categories, thereby ensuring greater flexibility for the learner.

    Measurement standards and equipment are maintained and calibrated on a daily basis in order to support accurate and traceable measurements in industry. There are currently no registered qualifications for the Metrology industry at any NQF level and training currently provided is not against nationally recognised qualifications. This qualification will promote portability and accessibility within the Metrology environment by providing learners with the competencies required. As current and past training has taken place against non-registered qualifications, this qualification will also be used as a benchmark in providing recognition for prior learning. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are already competent in:
  • Communication and Mathematical Literacy at NQF level 4.

    Recognition of prior learning:

    This qualification can be achieved wholly or in part through recognition of prior learning in terms of the defined exit level outcomes.

    Evidence can be presented in various ways, including international and/or previous local qualifications, products, reports, testimonials mentioning functions performed, work records, portfolios, videos of practice and performance records.

    All such evidence will be judged in accordance with the general principles of assessment described above and the requirements for integrated assessment.

    Access to the qualification:

    Access to this qualification is open, but learners should already have achieved the competencies reflected in the learning assumed to be in place. 

  • RECOGNISE PREVIOUS LEARNING?

    Integrated assessment:

    The practical, applied, foundational and reflective competencies demonstrated for the exit level outcomes in this qualification must prove that the whole competence is more than the sum of the parts of the competencies.

    Oral or written questioning regarding the reflective competencies within the qualification is essential. If the identifying and solving of problems, team work, organising one-self, the using of applied science, the implication of actions and reactions in the world as a set of related systems are not clear from the observation through a method of oral or written questioning, a case study can also be used to determine the person's development and integration of applied knowledge and skills.

    The planning, preparation, conducting and concluding of measurement and calibration related installations, maintenance, planning & design, and quality assurance can be assessed in one application.

    Applicable assessments tools must be used to establish the foundational, reflective and embedded knowledge of problem solving and application of the world as a set of related systems within the Metrology environment.

    A detailed portfolio of evidence is required to prove the practical, applied and foundational competencies of the learner.

    Assessors and moderators should develop and conduct their own integrated assessment by making use of a range of formative and summative assessment methods. Assessors should assess and give credit for the evidence of learning that has already been acquired through formal, informal and non-formal learning and work experience.

    Assessments should be structured in such a manner as to assess both specific and critical cross-field outcomes. During integrated assessments the assessor should make use of formative and summative assessment methods and should assess combinations of practical, applied, foundational and reflective competencies. 

  • INTERNATIONAL COMPARABILITY 
    The requirements for testing and calibration which support international trade are met via universally accepted practices. For more than 30 years the output of these activities in South Africa has been demonstrated as internationally equivalent through peer assessment of laboratory staff competence. This is largely due to the uniquely SA approach to metrology training since 1980.

    This training has been benchmarked internationally since 1998 both formally and informally and it was concluded that this training is not only on par with similar activities but in some cases was viewed as best practice in its own right.

    As leaders in the field of metrology we elected to consider the following countries and metrology training institutes with regard to this comparability study. A search for formal standards in this area was unsuccessful.

    United States of America:

    California State University, Dominguez Hills
  • 4 Year Degree Programme with a Measurement Science option.
    > Entry level High School GED.

    Central Georgia Technical College
  • Metrology Associate Degree.
    > Programme Length 107 Credit Hours.
    > Education Requirements High School graduate or GED recipient.
    > The Metrology Associate Degree programme is designed to meet the precision measurement needs of industry by preparing graduates through both theoretical and hands-on laboratory work to successfully enter the work force.
  • Metrology Diploma Programme.
    > Programme Length 90 Credit Hours.
    > Education Requirements High School graduate or GED recipient.
    > The Metrology diploma programme is designed to meet the precision measurement needs of industry by preparing graduates through both theoretical and hands-on laboratory work to successfully enter the work force.

    Australia:

    Swinburne University of Technology
  • Graduate Certificate of Engineering (Metrology and Quality).
    > Programme Length Two years part-time.
    > This programme provides training and experience in specific areas of Metrology and has the potential to prepare participants for higher degrees. It also provides the opportunity to serve a specialist group, which previously had not been adequately serviced by the education sector.

    United Kingdom:

    Brunel University (School of Engineering and Design)
  • Manufacturing Metrology
    > Entry Requirements: Normally an honours degree or equivalent usually in an engineering scientific or technological subject. Other qualifications such as Higher National diploma and suitable experience would be considered on an individual basis.
    > Programme Duration:
    > 1 year Full-time.
    > Part-time: 2 - 3 years - attendance for 4 block weeks.
    > Distance Learning - open ended.

    Note that although Brunel have discontinued providing this qualification due to market pressures, the content and level was considered relevant when it was benchmarked against the Certificate in Metrology.

    France:

    Ecole Supérieure de Métrologie
  • Diplôme d'Ingénieur Spécialisé de l'Ecole Supérieure de Métrologie (Diploma Engineer)
  • Titre de Mastère en Métrologie et Systèmes de Mesure (Masters)

    Conclusion:

    It was noted from the above that the range of these courses, both in level and content, is in line with the requirements of the South African Metrology industry. It was established that by pitching this qualification at NQF Level 5, candidates will be on a comparable level with their counterparts in other countries.

    Although it could be seen that the content of this qualification is similar to those used in the benchmarking exercise, an advantage of the Certificate in Metrology is the strong focus on competency and outcomes based results.

    SADC benchmarking:

    Whilst using the countries above as a yardstick for benchmarking the qualification was also evaluated against the requirements of the SADC countries for metrologists.

    In this case it was established that nearly all the countries have relied on either South Africa or Europe for obtaining the necessary skills and only Zimbabwe and Tanzania appear to have some metrology training. This is mostly been in specific areas of metrology and has not resulted in a broad based qualification such as in this Certificate. There was much interest displayed in this qualification and it may well be that it could be adopted by the region in the future.

    Certification - USA:

    The American Society for Quality ASQ offers a Calibration Technician Certification - CCT programme which is being used by employers to verify and certify the competency of calibration/metrology technicians in the United States of America. Their definition of a Certified Calibration Technician is one who tests, calibrates, maintains and repairs electrical, mechanical, electromechanical, analytical and electronic measuring, recording and indicating instruments and equipment for conformance to established standards.

    After careful analysis of this activity it has been established that the knowledge component of the Metrology Certificate NQF 5 is comparable and it is intended that ECSA will be approached to provide similar registration of Metrology Technicians in the future.
