Recent debates have highlighted the issue of school sector as an important consideration in student academic achievement. In 2004, a report contending that charter school students scored lower than students in public schools was fiercely contested.

Similarly, studies of students using vouchers to attend private schools have ignited heated debates about whether or not these programs boost student achievement, especially for poor and minority students.
