WorldSkills Occupational Standards (WSOS)
Occupation description and WSOS
The name of the skill competition is
Software Testing
Description of the associated work role(s) or occupation(s)
Software testing is comprehensive and systematic work, which uses various testing technologies and methods to verify that the functionality, reliability, security, ease of use, robustness, and portability of the software meet requirements, to find defects or errors in the software, and to ensure the quality of the software product. With the rapid development of ICT technologies such as artificial intelligence, big data, and the Internet of Things, the digital industry has made rapid progress. ICT software is applied to various fields such as industry, agriculture, transportation, information and communication, education and health, finance and insurance, and has helped to reshape and develop the world economy. However, defects or errors in software can bring economic losses or even life-threatening risks to human beings.
A Software Tester may work in a large or medium-sized company using software to power its services and operations, or in a company that provides specialist software services. Alternatively, they may act as a contractor to a wide range of businesses and clients. In larger organisations or projects, they may work in teams in order to test faster and more often. They may be embedded with developers to undertake testing throughout the software development process. Software testing is key to quality assurance.
The testing process is both manual and automated. Its purpose is to identify bugs and issues and to ensure that the software is fit for purpose before its release to end users. In addition to correct functioning, testing may include evaluating the design for ease of use by and attractiveness for the user.
Software Testers need comprehensive professional knowledge and skill. They should be able to write test plans based on documentary requirements, design test cases, select test tools, execute tests, and write test reports as the basis for the quality and evaluation of software products.
Broadly, the tasks involved are as follows.
- liaison with developers on projects
- communication with users to identify issues
- monitoring of software, programmes and applications
- planning projects
- writing test scripts
- use of coding languages
- reviews of documents and paperwork
- data collection and presentation of findings
- provision of feedback to software development teams
Software Testers always face strict deadlines and may need to work on several projects simultaneously.
This occupation has very strong growth potential, its importance being underlined by the scale of risk associated with a lack of quality control and assurance. For the same reason, entrants to the occupation are well supported by a wide range of global certifications which provide a baseline on which to grow outstanding performance.
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:
- ISCO-08: (http://www.ilo.org/public/english/bureau/stat/isco/isco08/)
- ESCO: (https://ec.europa.eu/esco/portal/home )
- O*NET OnLine (www.onetonline.org/)
