The outcome of the case was, a person shall be “given access to an adequate, publicly supported education,” regardless of the disability of the child. The court also ruled that a claim of insufficient resources could not be used as an excuse to exclude a child from free public education.
This case caused the system to realize that if you do not educate children that it is highly unlikely that they will be successful in life and that free public education is a right that EVERY child should have. Mills vs. the Board of Education led the way for the development of personalized educational programs for children with special needs. It was realized that children with special needs deserve the right to a free education, but they need specialized, intentional teaching and programs that can help them become successful students.
