Girls may achieve better due to having more positive role models in schools, 86% of teachers in primary schools are female, so from a young age, girls see that they can achieve highly, subsequently giving them goals and ambition, which may make them want to achieve well at school. Girls also naturally favour coursework, as they pay more attention to detail, take care of how their work is presented and are better at meeting deadlines, Goard found that the gender gap in achievement increased significantly once GCSEs (which involved coursework) were introduced. Girls also tend to achieve more highly than boys as they are often favoured by the teachers, as they are more cooperative and typically work silently with little fuss, these positive labels given to girls may form self-fulfilling prophecies, similarly when teachers label boys as a nuisance, it can form a negative self-fulfilling prophecy for them.
