A group of researchers from Stanford University under the direction of Dr. Sean Reardon analyzed the assessment results of Grades 3-8 students from over 11,000 districts in the country. The researchers contrasted what is often a significant difference between looking at the performance of students (achievement and test scores) and the growth that students in one district experience relative to those in another district. For each district, they calculated the average amount of growth in the five years between Grades 3 and 8. When looking at the results of York Suburban, the researchers found that our students actually experience 6.0 years of growth in the five years, which ranks in the 97th percentile nationally! It is yet another example of the value of a York Suburban education.
