The document discusses class differences in educational achievement, highlighting how pupils from working-class (w.c.) backgrounds often achieve less than those from middle-class (m.c.) backgrounds due to various external (home background) and internal (school-related) factors. It details cultural deprivation and material deprivation theories, emphasizing how lack of intellectual stimulation, restricted speech codes, and inadequate resources contribute to underachievement among w.c. pupils. Additionally, it addresses the role of labeling, self-fulfilling prophecies, and educational policies in perpetuating these disparities.
