Looking to improve student test scores? Multiple studies show improving air quality and lowering indoor air pollution levels can have a significant impact on test scores and student cognitive ability. <\/p>\n\n\n\n

In the past, we discussed air pollution reduces productivity on the job. Studies show this also extends to students in the classroom.<\/p>\n\n\n\n

Better Air Quality in Schools Leads to Better Test Scores<\/h2>\n\n\n\n

There are a variety of studies showing a simple correlation: lower pollution levels boost student test scores. What evidence do we have and by how much are test scores improved? <\/p>\n\n\n\n

Reducing PM2.5 in Schools Even a Little Can Make a Significant Impact<\/strong><\/p>\n\n\n\n

One study<\/a> in Israel analyzed data from 400,000 students taking a particular exam to see how air pollution affected results. The results: One standard deviation increase in PM2.5 was associated with a decline in student exam scores by 3.9 percent of a standard deviation. <\/p>\n\n\n\n

The study also found that the air pollution levels on the day of the exam had a significant impact, but not the air pollution levels in the days preceding. <\/p>\n\n\n

A study<\/a> of 10,000 US school districts also found a similar correlation. The study found just a one-unit increase in PM2.5 (\u00b5g\/m3) reducing students\u2019 test scores by 0.02 standard deviations.<\/p>\n\n\n

A Stanford study confirmed the negative correlation between test scores and air pollution. A 10-microgram increase in PM2.5 led to drops in all subject scores. <\/p>\n\n\n

Texas Schools Improved Air Quality, Test Scores Rose<\/strong><\/p>\n\n\n\n

Another study<\/a> of Texas schools studied the impact of schools that made improvements to indoor air quality (such as mold remediation and improved ventilation). The results were improving school indoor air quality led to an increase in test scores and an increase in the probability of passing tests by 3-4%. <\/p>\n\n\n\n

How Does Air Pollution Reduce Student Test Scores?<\/h2>\n\n\n\n

The serious health effects air pollution has on our health are well documented. Unfortunately, super small PM2.5 particles are so small they enter our bloodstreams and organs. <\/p>\n\n\n
