Nowadays, being a “good parent” is also assessed by how involved a child is at school. Where the child resists the educational process, the social field has devised a series of categories in which they can be lumped as with tyrannical children, advanced children and school phobia. This injunction to achieve at school shakes up the dynamics of the family between parental relinquishment and infantile over-excitement. A family therapy is used to exemplify this process, in particular through a session where work around a written sentence serves to provide a metaphor for the family’s structural evolution.
