Most institutions use grades to compare roles within their institutional structure and also to relate compensation.
Employee grades can be used to represent seniority of employees within the institution, and to define the number of periods an employee of a particular grade should teach or work.
In relevance to your institution, you can create as many employee grades as you like.
Menu > Administration > Human Resource > HRSetting > Add Employee Grade
Complete the fields as instructed above. Click create once you are finished.
The following is to inactivate, delete or edit the grades you have created.
