This survey is a qualitative study about how teachers see on the concept student leverage and what they say about how they in practice work with it. We have chosen to examine the subject from a teacher’s perspective, because almost all investigations and literature, that we have found, discuss student influence from a student’s perspective. That’s why we are interested to examine what teachers think of the subject. We did three focus group interviews with teachers from preschool classes up to class 6. The teachers considered that student influence is when teachers listen to the students' interests and the lesson content then acts about that. Student influence is also that the students may influence the organization of social environment, evaluation and approaches. Evaluation was something the teachers regarded should be done, but they said that they didn’t have time to do it. All teachers expressed that when they work with student influence, it is through class - and pupil ' council. They considered that the students through this might have leverage in both classroom and school. We have come to a result that student effect means that the students should have leverage in both contents and approaches. Student effect is also that the student can have influence in his/hers situation in the school.
