To estimate the success of a project it is necessary to collect and analyse data. Depending on the phase after which the evaluation is carried out it gives information about the status of the project or about the perspectives in the future. It proves which measures are successful and worth to continue. The problem is to find out which factors provide useful information and how to interpret and use them. This paper is about the development and effectiveness of a project which supports students in the study entry phase. It was monitored and different measures of evaluation were used. One of them was to observe the written exam results of all bachelor study programs of our university. In the process of interpreting the data, it was discovered that each study program was a little bit different and the challenge was to find a method to suit the requirement of all. This paper discusses this approach, shows what statements can be made and where the limits of this evaluation lies.
