How does a sponsoring employer decide which is the correct SOC Code for a role?
The sponsor must identify the best fit SOC Code for the role taking into account the job content of the role.  Unhelpfully the SOC Codes do not include lists of example job tasks.  ONS materials are available to help with this, including the ONS Occupation Coding Tool.  This tool has a search function which enables sponsors to narrow down the relevant codes and sets out the typical job tasks and common job titles for the relevant occupation.
