Final answer:
The norms that set expectations for the level of work performance in a group are known as 'achievement norms.' These norms define the quality and amount of effort that group members should contribute to achieve shared goals and maintain group standards.
Step-by-step explanation:
The category of norms that determines the quality and quantity of work expected from group members is typically referred to as achievement norms. These norms influence the level of performance that is regarded as acceptable within the group setting, and they shape the expectations for individual contributions toward group goals. Achievement norms can vary greatly among different groups, organizations, or cultural contexts, but their main function is to standardize what constitutes good performance and how much effort members should put into their tasks.
Group expectations are important concepts within the study of social norms, affecting behaviors or practices that are required for or expected of the members of a particular group. In the context of a formal organization, these may be articulated within legal frameworks, policies, or organizational guidelines. Formal norms, such as laws and social policies, serve as detailed and enforceable standards that guide behavior within societies and institutions.
