leting this element of the evaluation. We analysed evidence from the various means of inquiry used, and then triangulated this as part of a process of bringing together different types of information to synthesise findings, conclusions and recommendations. 4.4 Limitations There are several key limitations to the research that are worth highlighting. Length of time since tool launch. This evaluation sought to evaluate the TFD and all its corresponding tools and applications. However, the tool was first launched in 2015 and has undergone many changes and improvements since this time. This created some challenges, since many participants were not employed at Bristol City Council at the time of its launch, and those that were, experienced understandable difficulty recalling details to do with its roll out. To mitigate this, we spoke to as many participants as possible over a range of years using the TFD. Breadth of schools. Although the TFE has now been rolled out to over 100 schools across Bristol, due to limited availability of school staff and other unforeseen constraints, we were only able to engage with 6 schools as part of this research (2 secondary, 2 primary, 1 all through, and 1 SEND). Future research in this space should consider engaging more schools. Survey numbers and representation. The relatively small survey size poses some limitations, and the sample is not considered to be representative. Although the survey reached a range of people from across teams, some teams (Triage and Early Intervention) are overrepresented in the survey sample and therefore are likely to have disproportionately impacted the survey results. We also suspect that regular users of the TFD were more likely to complete the survey, which may have impacted the feedback we gathered our assu
