WorldSkills Occupational Standards (WSOS)

Occupation description and WSOS

The name of the skill competition is

Chemical Laboratory Technology

Description of the associated work role(s) or occupation(s)

The work of laboratory chemical analyst is the basis of the product quality in many industries. Chemical analysis is necessary to control the compliance of the properties of raw materials, intermediate stages of the technological process, and finished products with current standards.

The laboratory chemical analyst performs laboratory analyses, tests, measurements aimed at determining

  • The qualitative chemical composition of a substance
  • The quantitative ratio of chemical elements and compounds within them
  • Processing of the obtained data,
  • Reporting results of analyses and
  • Other types of laboratory work

according with the requirements of standards and specifications. The scope and complexity of the tests performed depend on the type of tasks set by the employer.

The role includes knowledge of the following objects of professional activity:

  • Natural and industrial materials;
  • Synthetic materials;
  • Equipment and instruments;
  • Regulatory and technical documents.

Laboratory chemical analysts should be ready to determine the optimal tools and methods for the analysis of various natural and synthetic materials, to perform qualitative and quantitative tests using modern chemical, bioanalytical and physicochemical analytical methods. They should be able to act logically and systematically, complying with sanitary and hygienic requirements and occupational safety and health standards.

Usually, laboratory chemical analysts work in the chemical laboratories of quality control departments, research and development departments, or in environmental departments in plants in various industries: chemical, petrochemical, pharmaceutical, food, bioproducts and the supply of construction materials, paint and varnish, polymers, defence and many others.

The WorldSkills Occupational Standards (WSOS)

General notes on the WSOS

The WSOS specifies the knowledge, understanding, skills, and capabilities that underpin international best practice in technical and vocational performance. These are both specific to an occupational role and also transversal. Together they should reflect a shared global understanding of what the associated work role(s) or occupation(s) represent for industry and business (www.worldskills.org/WSOS).

The skill competition is intended to reflect international best practice as described by the WSOS, to the extent that it can. The Standard is therefore a guide to the required training and preparation for the skill competition.

In the skill competition the assessment of knowledge and understanding will take place through the assessment of performance. There will only be separate tests of knowledge and understanding where there is an overwhelming reason for these.

The Standard is divided into distinct sections with headings and reference numbers added.

Each section is assigned a percentage of the total marks to indicate its relative importance within the Standards. This is often referred to as the “weighting”. The sum of all the percentage marks is 100. The weightings determine the distribution of marks within the Marking Scheme.

Through the Test Project, the Marking Scheme will assess only those skills and capabilities that are set out in the WorldSkills Occupational Standards. They will reflect the Standards as comprehensively as possible within the constraints of the skill competition.

The Marking Scheme will follow the allocation of marks within the Standards to the extent practically possible. A variation of up to five percent is allowed, if this does not distort the weightings assigned by the Standards.

General notes

WorldSkills is committed to ensuring that the WorldSkills Occupational Standards fully reflect the dynamism of internationally recognized best practice in industry and business. To do this WorldSkills approaches a number of organizations across the world that can offer feedback on the draft Description of the Associated Role and WorldSkills Occupational Standards on a two-yearly cycle.

In parallel to this, WSI consults three international occupational classifications and databases:
