The working atmosphere in the classroom is an important variable in the process of education, with several studies suggesting that classroom climate has a significant impact on student attainment. Terry Haydn describes the use of a 10 point scale for conceptualising the working atmosphere in the classroom as a continuum; between a climate which is ideally conducive to learning (level 10), to a level where learning is severely constrained by the poor behaviour of some pupils (level 1). The scale encourages teachers, student teachers, school managers and school governors to reflect on the factors influencing the working atmosphere in the classroom. Publication
