The correct answer is accountability and scientifically-based instruction.
Both No Child Left Behind (NCLB) and the Individuals with Disabilities Education Act (IDEA) emphasize accountability in education and the use of scientifically-based instructional methods to improve educational outcomes, particularly for disadvantaged students and those with disabilities. While NCLB focuses more on accountability regarding student performance and achievement, IDEA is centered around ensuring that children with disabilities are provided appropriate education services.
The other options presented (funding for low-income schools, all children to achieve advanced scores, and all of the above) are not accurate mandates of both laws directly.
