 for the 903 and/or Ofsted Annex A returns. Table 1 below shows the number of data items collected which can be considered as 903 data, Ofsted Annex A data, or both 903 and Ofsted Annex A data. Table 1: Total number of data items collected by category Categories of data items Number by category Percentage % of all data items 903 40 3% Ofsted Annex A 20 1% Both 903 + Annex A 18 1% ‘Local’ data 1,497 95% 29 DfE Project 2A: User research into social worker inputted data to CMS Total number 1,575 A total of 78 data items, out of 1,575 included in the data matrix, are categorised as ‘statutory data’ and collected as a statutory requirement. Of these 78 data items, 21 are collected by all four participating LAs via the forms mapped onto the data matrix:  8 data items are collected for 903 (Table 2)  6 data items are collected for Ofsted Annex A (Table 3)  7 data items are collected for both 903 and Ofsted Annex A (Table 4) The remaining statutory data items included in the data matrix, which appear to not be collected by some LAs, are stored in other parts of the CMS but not collected via the forms included in this project. In general, practitioners found data items collected as ‘statutory data’ helpful in supporting children, young people, and their families. Of the collected statutory data items, there are a small number that practitioners collect but for which they do not understand the reasons for collecting them. For example, ‘Address’ (item 11). The terms ‘current address’ and ‘second address’ are both used, making this confusing for practitioners. There is a need for either more guidance or for the language on the form to be improved. Please refer to the data matrix in appendix one for more examples. Table 2: Data items collected as ‘903’ by all four participating L
