A positive school climate is characterized by a higher degree of well-being among students, reduced bullying, and improved academic performance. While many initiatives are aimed at creating a positive school climate, discussions in both research and theory frequently fail to acknowledge the essential role of school personnel. This study examines a purposeful sample of Swedish middle-school students (4th to 9th grade) of school personnel’s noticing in fostering or hindering a positive school climate. Fifteen (15) focus groups and 19 semi-structured interviews were analyzed, covering 133 participants selected from three schools (age range 10 to 16 years) in a Swedish municipality. Drawing on a framework of professional noticing and positive school and classroom climate, the investigation was conducted using a case study approach and analyzed with the help of content analysis. The results highlighted the importance placed by students on school personnel noticing appropriate things/events and responding accordingly. For this to happen, personnel need to (a) notice and make themselves visible; (b) be actively observing as a prerequisite to their noticing; (c) be receptive to noticing; (d) notice and grasp a full picture, including students’ perspectives; and (e) connect their noticing with appropriate actions.
