pes of local data varies across LAs  A small number of data items, 38 out of 1,575, is collected by all four participating LAs as local data Qualitative feedback was collected for most of the data items listed in the data matrix. It is important to remember that we worked with a small sample of practitioners. Feedback was collected from only one practitioner for some data items. This means the insights presented here give a general overview of data and information collected by the four participating LAs. They are valid insights, but they are not statistically reliable. The data matrix revealed that most data items, around 95%, are collected as ‘local’ data. The remaining 5% is collected as statutory data, for 903 returns, or for Ofsted Annex A or for both. CSC professionals in each LA were asked to tag each local data item with the primary reason why it is collected locally. If applicable, they could tag it with a secondary reason too. Across all LAs, the top reason given for collecting local data items is to help social work practitioners and/or the child/young person. The main and most important insight emerging from the project is that all information and data items collected are helpful. All information collected is important and directly helps practitioners and other colleagues within the LA supporting children, young people, and their families, throughout their care journeys. On occasions when data items are considered not helpful, it is usually because they are duplicated, or the language used is not user friendly. Statutory data A minority of data items included in the data matrix are collected as ‘statutory data’ 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
