44 Annexe 6 : The child online safety index (COSI) from the DQ Institute 40 The 2022 COSI Assessment Framework The COSI score represents the overall level of a nation’s performance on child online safety measures. The 2022 COSI scoring system is based on 35 indicators related to 12 topics of child online safety across 6 stakeholders—namely, children, families, schools, ICT companies, and soft and hard infrastructures of the government. Each stakeholder score is measured based on the topic scores that belong to each stakeholder, and each topic score is measured based on the indicator scores that belong to each topic, in a hierarchical structure. Stakeholder scores, rigorously defined by the Performance Level Descriptors (PLDs), are designed to give policymakers and national leaders a better understanding of their countries’ performance on child online safety. Topic scores are the indicators of performance in different areas of stakeholders’ efforts. The indicator scores can be used to develop assessment instruments, learning curriculum, and/or tasks for relevant groups within each stakeholder.
Computation of Scores The COSI score is calculated by successively combining the scores from each level of the hierarchy. The 6 Stakeholder scores combine the scores of 12 Topics, and the 12 topic scores combine the scores of 35 indicators.
At the lowest level, each score of the 35 Indicators is standardized and measured based on a weighted average of the sub-indicators belonging to each indicator. It is then transformed to a value between 10 and 100, with 10 being the lowest and 100 being the highest possible score.
These indicator scores are combined to create a score for each of the 12 Topics, and eventually a score for each of the 6 Stakeholders. The overall COSI score is then calculated as a weighted average of the 6 Stakeholder scores.
Performance Level Descriptors (PLDs) Performance level descriptors are a means of describing performance in terms of levels or categories of performance. For the COSI scores, Stakeholder and Topic outcomes are reported in terms of three levels of performance: Level 1, Level 2, and Level 3.
THE PLDS FOR STAKEHOLDER AND TOPIC SCORES CAN BE CONSIDERED POLICY PLDS DESIGNED FOR policymakers. They are general descriptors that articulate the goals and rigor for the final performance standards. These descriptors set the tone for the subsequent descriptors for Indicator scores, which can be considered as range PLDs. They are content-specific descriptors that may be used by corresponding stakeholders to guide assessment or learning development and/or resource enhancement.
