Final answer:
According to Erikson, a child focused on academic success and receiving a report card is in the Industry versus inferiority stage, which occurs in elementary school and is key to building a sense of competence and a healthy personality.
Step-by-step explanation:
A child who is learning the importance of academic success in school based on receiving a report card is in the Industry versus inferiority stage of Erikson's psychosocial development. During the elementary school stage (ages 7-11), children are building competences and a sense of achievement in various areas, including their academics. In this stage, the child begins to develop a sense of pride and accomplishment in their capabilities or may feel inferior when they perceive themselves as not measuring up to peers. The outcome of this stage is crucial for building a healthy personality and a sense of competence, which are important for their future development.
