In calculating the overall school achievement score earned by schools, the State Board of Education shall (i) use a composite approach to weigh the achievement elements based on the number of students measured by any given achievement element and (ii) proportionally adjust the scale to account for the absence of a school achievement element for award of scores to a school that does not have a measure of one of the school achievement elements annually assessed for the grades taught at that school. The overall school achievement score shall be translated to a 100-point scale and used for school reporting purposes as provided in G.S. 115C-12(9)c1., 115C-218.65, 115C-238.66, and 116-239.8.
