The ³Ô¹ÏȺÖÚ Welsh-English bilingual communicative development inventory (BU WEB-CDI) is a questionnaire that professional and personal caregivers can fill in to tell us about a child’s language and communicative development.
³Ô¹ÏȺÖÚ is situated across two counties, Gwynedd and Ynys Môn, which have the highest proportion of Welsh speakers in Wales. We have close working relationships with local nurseries, schools, and clinics, making us uniquely placed to develop effective Welsh-English bilingual screening and intervention tools.
The ³Ô¹ÏȺÖÚ WEB-CDI was developed expressly to meet a local need for suitable early years bilingual language assessment tools, and in response to a number of Welsh Government agendas. These include the , which aims to increase the number of Welsh speakers to one million by 2050, the , and the , which aims to ensure that all children in Wales meet key developmental milestones and are school ready.
