How dirty classrooms could be negatively affecting your students and teachers

Having a dark, dirty and poorly ventilated school does more than make for a bad first impression for potential students and parents. It could also drastically affect student achievement and teacher morale.

“Students and teachers need clean, roomy, well-ventilated and well-lit spaces for teaching and learning,” Carol Burris, executive director of the Network for Public Education, told The Atlantic in an article titled “Reimagining the Modern Classroom.”

And studies back this up.

“With respect to students, school facilities affect health, behavior, engagement, learning and growth in achievement,” the Penn State Center for Evaluation and Education Policy Analysis found. “Thus, researchers generally conclude that without adequate facilities and resources, it is extremely difficult to serve large numbers of children with complex needs.”

But U.S. school facilities received a D+ in the most recent Infrastructure Report Card, released by the American Society of Civil Engineers in 2017. The report also found that 24 percent of public school buildings are in poor or fair condition.

Here are three ways poor learning environments could be negatively affecting your students:

1. Increased absenteeism and sickness

Ever heard of “sick building syndrome”? It’s real, and can affect school attendance.

Poor air quality can have a huge impact on absenteeism, especially on students with asthma. And poor ventilation allows “bacteria, viruses and allergens that contribute to childhood disease” to circulate, according to the Penn State paper.

Researchers at Lawrence Berkeley Labs “noted an increase of 50 percent to 370 percent in the incidence of respiratory illness in spaces with low ventilation rates, as are commonly found in schools, compared to spaces meeting industry-accepted standards,” according to the 2016 State of Our Schools report from the 21st Century School Fund.

2. Reduced morale and productivity

Lighting plays a major role in both morale and productivity.

“Research has shown that not only does classroom lighting boost the morale of teachers and students, (but) appropriate amounts of natural lighting also reduces off-task behavior and improves test scores,” according to the Penn State paper.

Poor learning environments affect teachers as well as students.

Nineteen percent of teachers who left the profession cited “dissatisfaction with working conditions,” according to a Learning Policy Institute study. And teacher turnover is costly. It hurts student achievement and leads to shortages, and it can cost up to $21,000 to replace a new teacher in an urban school district, according to Education Week.

3. Lower test scores

In addition to productivity, poor lighting could directly affect test scores.

A study in California found that students scored as much as 25 percent higher on standardized tests in classrooms with more natural light. In an earlier study, students with “the most exposure to natural daylight progressed 20 percent faster in math and 26 percent faster in reading than students who were taught in environments with the least amount of natural light.”

Even classroom temperature can affect student achievement. The Penn State Center for Evaluation and Education Policy Analysis reports that the ideal temperature range for learning in reading and math is 68-74 degrees.

Having an efficient and thorough custodial and preventive maintenance program makes it possible to create and maintain a clean, comfortable, pleasing atmosphere conducive to learning. Not only does it look nicer, but it can have a measurable positive effect on your students and teachers.
