What is the main argument, narrative and effect of this text? What evidence and examples support these?

The authors structure their argument around three metrics: student health, student thinking, and student performance. They define these as follows:

• Student health: the overall physical and biological health of a school building occupant.
• Student thinking: short-term impacts on cognitive function and mental well-being.
• Student performance: the successful long-term academic performance of students.

Through their review of more than 200 studies, they conclude that there is unambiguous evidence for negative effects of low environmental quality on all three of these metrics. Although it is discussed in less detail, they also reference studies that provide evidence for the improvement of these three metrics when issues with school infrastructure are addressed.
