It is the main federal law for K-12 general education. it covers all students in public school.

Some Contrasts
Disaggregate data by race and by wealth, but shows little promise of remedying the systemic under resourcing of needy students
Support a testing regime that measures wealth rather than provides a rich kaleidoscope of experience and knowledge to all.
Evaluating teachers by their student's test scores raises compelling ethical questions.
"It also creates new risks that states or districts that do not have the will, capital, or capacity to lead and continuously improve will stall or regress, and that students in those places will fall through the cracks"
Scott Palmer, Education Counsel
The school quality indicators allow states (and in turn districts and schools) to bring in a whole variety of measures beyond standardized tests.
All students have equal access to high-quality teachers, stimulating curriculum and instruction and adequate school resources (such as computers, libraries, field trips, and learning resources)
Schools and school personnel must not be evaluated on elements where they are denied the resources and supports they need to be successful.
