Does Class Size in Arizona Matter? Research says “Yes”

Thursday, February 20, 2014   

PHOENIX – As school districts across Arizona continue to cope with dwindling budgets, new research examines the impact of class size and the role that crowded classrooms can play in students' educational outcomes.

Diane Schanzenbach, an associate professor at Northwestern University, points out in the study that having a manageable class size really does make a difference in how well students do in school.

"Much in line with parents' common sense and what teachers know, smaller classes mean that children learn more, they have better achievement and better lifetime outcomes if they're in smaller classes," Schanzenbach says.

Her research says student-teacher ratios in public schools fell steadily over the past 40 years, but that trend has changed recently.

In the last five years, the average class size in the U.S. has increased 5 percent, to almost 22 students per classroom.

The National Center for Education Statistics says the average class size in Arizona is just over 21 students.

While lower class size may cost districts more in the short term, Schanzenbach says it may prove to be the more cost-effective policy overall.

"We have to be very careful with our resources, especially when the economy is bad,” she explains. “But we can't forget that investing in high-quality schools is an investment that's going to pay off over the long term.

“We shouldn't do something today that's penny wise and pound foolish, like increasing class sizes."

Schanzenbach stresses her research has determined that reducing class sizes to between 18 and 20 students will pay for itself, in terms of improvements in children's future well-being.
