Bachelor’s degree is generally required to work as ICT accessibility tester. However, this requirement may differ in some countries.

ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:

• the nature of the work performed in an occupation in relation to the characteristic tasks and duties
• the level of formal education required for competent performance of the tasks and duties involved and
• the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.

ICT accessibility tester is a Skill level 4 occupation.

These occupations, although different, require a lot of knowledge and skills similar to ICT accessibility tester.

Execute ict user research activities: Perform research tasks such as recruitment of participants, scheduling of tasks, collecting of empirical data, data analysis and production of materials in order to assess the interaction of users with an ICT system, program or application.
Address problems critically: Identify the strengths and weaknesses of various abstract, rational concepts, such as issues, opinions, and approaches related to a specific problematic situation in order to formulate solutions and alternative methods of tackling the situation.
Measure software usability: Check the convenience of the software product for the end user. Identify user problems and make adjustments to improve usability practice. Collect input data on how users evaluate software products.
Test system accessibility for users with special needs: Examine whether software interface complies with standards and regulations so that the system can be used by people with special needs.
Replicate customer software issues: Use specialised tools to replicate and analyse the conditions that caused the set of software states or outputs reported by the customer in order to provide adequate solutions.
