Since its ratification (NCLB) has received both praise and criticism from educators and parents. The No Child Left Behind Act is a reauthorization of the Elementary and Secondary Education Act that was passed in 1965. The purpose of this article is to discuss the pros & cons of "No Child Left Behind" and the core requirements for its implementation. The law states that if schools don't not make AYP for three years in a row, they must provide free tutoring and supplemental educational services. Educators and parents feel that the No Child Left Behind Act has many unsolved issues and parents have expressed concerns as to whether or not their children are not truly learning or "taught to the tests." School districts also share in this frustration due to inadequate funding. Congress has not provided the funds needed to implement the necessary services mandated by the law and therefore has created an added burden on the states.
