When schools feel pressure from league tables, they’re driven to boost the measured performance of their students. That external emphasis on visible results can lead teachers to label or categorize students in ways that lift the school’s apparent achievement. For example, focusing attention on students deemed most likely to achieve high marks, or shaping who is counted in key metrics, can make averages look better in the league tables. This is a direct response to the pressure created by those external rankings, where the goal is to present a stronger overall score. The other options don’t map as directly to this behavior. Funding decisions can be influenced by league-table results, but the specific practice of labeling students to boost apparent performance is most clearly connected to the pressure from the league tables themselves. Parental involvement affects expectations and support but isn’t the mechanism that leads to labeling for the sake of improving league-table standings. Curriculum changes alter what’s taught and assessed, but the question focuses on how external rankings drive labeling practices, not on changes to content.

Before 1870, schooling in Britain wasn’t organized as a universal, state-supported system. Wealthier families could afford private schools, tutors, or higher-status grammar schools, while many poorer children had limited or no access to formal education beyond church or charity schools. Provision varied by locality and by class, so whether a child could attend school largely depended on social position and means. This is why the statement that access depended on social position best captures the period. The other ideas imply universal state funding, equal access, or universal private tutoring, none of which match the reality before 1870, when education was far from universal and strongly shaped by class and local resources.

Formal social control in schools means official rules and the sanctions used to enforce them by the institution. It involves codified policies, disciplinary procedures, and punishments administered by staff or administrators to regulate student behavior. Among the options, the description of discipline carried out by staff, along with school rules and punishments, best fits this idea. It reflects the formal mechanisms schools use to regulate behavior through established authority and clear consequences. The other options reflect informal or non-enforcement aspects: peer influence to conform is social pressure from classmates rather than official sanctions; informal learning from peers is about shared knowledge without enforcement; student self-governance involves student-driven governance, which may guide behavior but typically doesn’t involve formal sanctions imposed by the school.

Discrimination in education based on sex is forbidden by a law that specifically targets equality in educational settings. The Sex Discrimination Act 1975 establishes that treating people differently because of their sex in education—such as admissions, course access, or how they’re treated by schools and universities—is unlawful. This makes it the best answer because it directly addresses prohibiting sex-based disparities in education, providing a clear standard for fair access and treatment. By comparison, the Equal Pay Act focuses on wage differences for equal work, not on education-wide discrimination; the National Curriculum outlines what is taught rather than regulating discrimination; and the GIST program is an outreach initiative to support girls in science, not a broad policy against sex discrimination in education.
