## ISCO skill level

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.

Mathematician is a Skill level 4 occupation.

## Essential knowledge and skills

### Essential knowledge

This knowledge should be acquired through learning to fulfill the role of mathematician.

- Mathematics: Mathematics is the study of topics such as quantity, structure, space, and change. It involves the identification of patterns and the formulation of new conjectures based on them. Mathematicians strive to prove the truth or falsity of these conjectures. There are many fields of mathematics, some of which are widely used for practical applications.
- Algebra: The subdiscipline of mathematics that uses formulae, symbols, and equations to represent and manipulate numbers and quantities.
- Statistics: The study of statistical theory, methods and practices such as collection, organisation, analysis, interpretation and presentation of data. It deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments in order to forecast and plan work-related activities.
- Scientific modelling: Scientific activity consisting in selecting the relevant aspects of a situation and aiming to represent physical processes, empirical objects and phenomena to allow a better understanding, visualisation or quantification, and to enable simulation that shows how this particular subject would behave under given circumstances.
