In Hobson v. Hansen, what was found to be unconstitutional?

In the case of Hobson v. Hansen, the court found that ability tracking based on intelligence testing was unconstitutional. This decision focused on the implications of intelligence testing systems that were used as a basis for placing students into different educational tracks. The court held that the testing practices disproportionately affected minority and low-income students, leading to segregation within schools. This reinforced the understanding that educational opportunities should not be determined by biased assessments and that all students deserve equal access to quality education, regardless of socioeconomic background or results from standardized tests. The ruling emphasized the need for fair and equitable treatment of all students in the educational system.
