- The authors present seven propositions about the dynamics of tracking based on their fieldwork and transcript analysis.
- One proposition is that race, ethnicity, and social class signal ability and motivation and consequently influence curriculum decisions. The authors arrive at a conclusion that does not point to a single theoretical explanation.
- Structural, cultural, and political factors all influence tracking decisions.
- Tracking decisions result from differentiated hierarchical curriculum structures; school cultures that are alternatively committed to common schooling and accommodating differences; and political actions by individuals within those structures and cultures aimed at influencing the distribution of advantage.
