Does the size of a district have an impact on student achievement?

National research does show that in some of the largest districts in the country, Los Angeles, Miami-Dade, Detroit, for example, - all of which have hundreds of thousands of students - student achievement as evidenced by test scores is lower than in smaller districts around the U.S. However, a recent Utah study of districts within the state showed no difference in student achievement between large and small districts. It is important to note that Utah’s largest districts are small in comparison to the large districts studied nationally.
