A method and a score management node for supporting service evaluation by obtaining a perception score reflecting a user's experience of one or more services delivered by a telecommunication network. The score management node receives a network measurement related to a current service event of service delivery to the user within a predefined time length from a previous service event, and determines a correlation level reflecting the user's perception of the current service event as correlated with the previous service event. A quality score is determined for the current service event, reflecting the user's perception of quality of service delivery and an associated significance reflecting the user's perception of importance of service delivery, based on the network measurement and the correlation level. The perception score is then calculated for the current service event as the quality score weighted by the associated significance and is made available for the service evaluation.
