COMPENCA is the first joint project of CIRIC, starting in November 2020 with the focus on children’s right to express themselves during decision-making. COMPENCA promotes future and current child protection workers’ access to knowledge, and the continued effort to professionalise the workforce and their duty to enforce the rights of the child. Studies indicate that assessment practices in Estonia and Norway are done for the child rather than with the child, which is in breach of the Convention on the Rights of the Child Art. 12.2, which stipulates that children are legally entitled to be heard during child protection casework. In order to increase competence and support the professional growth, an e-book will be published and short-term courses held for the educators to address best practices and methods to effectively engage children in the participation process. Therefore, the main objective of the book is to explain and discuss children’s right to express themselves during decision-making and assessment process in child protection services. The aim of the book is to be instructive to the workforce, ensuring a deeper impact on the field of practice, and consequently how children and their families are treated by the services.
