A correlation is defined as a causal, complementary, parallel, or reciprocal relationship found to exist between various variables examined during an investigation and based on specific criteria. The value of a correlation co-efficient can vary from minus one to plus one. A minus one indicates a perfect negative correlation, while a plus one indicates a perfect positive correlation. A correlation of zero means there is no relationship between the two variables. When there is a negative correlation between two variables, as the value of one variable increases, the value of the other variable decreases, and vise versa. In other words, for a negative correlation, the variables work opposite each other. When there is a positive correlation between two variables, as the value of one variable increases, the value of the other variable also increases. The variables move together.

Abstract
Since the introduction of the No Child Left Behind (NCLB) Act of 2001, education in the United States has, in the words of President Bush, been seen as “a national priority and a local responsibility.” The first of the four basic education reform principles stated in the NCLB Act is local accountability for results. The second principle, flexibility and local control, empowers states to create their own standards and to test every student’s progress using tests aligned with these standards. In addition, there are also programs to promote the alignment of technology with educational goals within the NCLB legislation. In more and more states, school performance is assessed by means of a standardized assessment test which is designed to assess the academic level of students, schools, and districts. It is also intended to assist in identifying students’ strengths and weaknesses and to foster improvements in academic achievement. In one such state (that will remain anonymous) the reading and mathematics portions of the exam are administered to grades 5, 8, and 11.
