It is statutory that teachers shall document their student's development of knowledge in different subjects. The teachers employed by Sundbybergs municipality have been commissioned to do the documentation in the web-based electronic system Projekt- och Omdömesdatabasen, P.O.D.B. The purpose of this study was to investigate witch effect the IT-solution P.O.D.B has brought for the teachers in their task of student documentation. By conducting interviews and questionnaire studies I have been looking for answers to if the target achievements have increased by using the IT-solution, and if the teachers are aware of what they may or may not write about their students in the system. The conclusions I have been able to draw through my studies are that the teachers have accepted the commission to use P.O.D.B. But they didn't feel assessorial in the decision of beginning to use computers for the task of documentation. Their work has because of this become more time extensive, and there is some insecurity about the formality of the system. The effect of the decision has resulted in that the targets have been made more visible and the target achievements have increased, and the storage options have made the student information more readily accessible.
