Ways in which elementary and junior high school teachers can use the My Class Inventory (MCI) to assess their students' views of classroom climate are discussed. The climate of a group is defined as the quality of the internal environment that persists over time and is experienced by members of the group. The short form of the MCI, which is considered the most appropriate climate instrument for young children, consists of 25 statements, with five statements each for the dimensions of satisfaction, friction, competition, difficulty, and cohesion. Research indicates that each of these dimensions is related to learning in classrooms. Teachers can use profiles of classroom climate as a basis for thinking about ways to improve the learning environment and increase student achievement. Guidelines for administering the measure to students are offered. (RH)
