 item was considered not helpful to record by practitioners in their work with children and families, rather specific data items are considered useful to collect but unhelpful in certain contexts, primarily due to duplication and the use of language. The reasons practitioners gave for why they consider some data items burdensome have been tagged in the data matrix (see appendix one). Table 6 shows the number and percentage of data items that were assigned a certain tag. This show us that Duplication and Language/Guidance/Design were the top reasons practitioners gave for finding data items unhelpful.

The following duplication reasons were identified by practitioners as reasons for a data item not being helpful:  the information is already in the system and does not change (for example: item 115 ‘Summary of child's background/history and why they need foster care’)  the data item is collected twice within the same form (for example: item 39 ‘In the child's view: what makes you, you?' and item 40 ‘Where does the child feel they are at the moment?’)  the same information is collected in more than one form (for example: item 11 ‘Address’) This was further explained in the qualit
