This report presents national survey results of public school teachers' opinions on the relationship between interior design and academic performance. The 1,050 teachers surveyed reveal that they recognize the relationship between interior design and academic achievement and that most teachers see the advantages of classroom carpeting relative to acoustics, comfort, and flexibility. While three-fourths of those surveyed consider a school's interior design "very important" for creating a good learning environment, only 18 percent gave their classroom an "A" for overall design. Most respondents rate carpeting as an important design feature. Carpeting is also the most prevalent and most popular of classroom floor coverings. While respondents who have classroom carpeting give their classrooms higher marks than classrooms without carpeting, elementary school teachers find carpeting particularly appealing. An appendix presents the survey's regional groupings by state, and includes seven figures and three tables. (GR)
