Public schools can remain segregated even when law no longer assigns students explicitly by race. Residential patterns, district boundaries, transportation, admissions rules, school choice, and family resources shape where students enroll. This is de facto segregation when separation persists through practice and social conditions rather than a law commanding it. Calling it de facto does not mean that it arose by accident.

Funding systems matter because schools rely on different mixes of local, regional, and national revenue. A property-based system can connect school resources to neighborhood wealth. Equal spending also does not guarantee equal educational conditions. Students who need language support, disability services, transportation, or counseling may require different resources to reach comparable access.

Within schools, tracking places students into courses or programs at different levels. Grouping can match instruction to current readiness, yet early placement may reflect unequal prior opportunity, subjective judgment, or biased expectations. Because tracks control later course access, a small initial difference can grow. A fair evaluation asks how placement occurs, how often it is reviewed, and whether students can move.

School discipline is another pathway. Removal from class changes instructional time, relationships, and later records. A disparity in suspension rates establishes an unequal pattern. To explain it, researchers examine behavior, reporting, discretion, school climate, rule design, and responses to comparable conduct. The group category itself is not a mechanism.

Quick review: Achievement gaps describe measured outcomes. Opportunity gaps identify unequal access to conditions for learning. Segregation can persist through housing and policy without an explicit racial assignment. Tracking and discipline matter when they change instruction, records, and later opportunity.
