"[I]t is sometimes difficult for stakeholders, who represent different interests in the system, to come to agreement as to key issues with respect to information sharing for individual case management. These include the purposes and value to youth of information sharing; what are the appropriate limits on sharing; and how to minimize the potential negative collateral consequences of information sharing such as self-incrimination and net widening. In addition, with respect to data collection, aggregation and sharing for law, policy and program development, stakeholders in jurisdictions often make the mistake of developing systems before identifying the key questions they want answered by the aggregated data. Similarly, with respect to program evaluation and performance measurement, stakeholders must first determine the outcomes they wish to achieve and the indicators they will use to measure progress towards those outcomes, and then take their baseline measurements. Without this preliminary legwork, jurisdictions could set up information sharing systems that do not fully meet their needs." The Models for Change Information Sharing Tool Kit – 2d Edition is "is designed to assist jurisdictions in implementing information and data sharing initiatives in support of juvenile justice reform initiatives. Three distinct levels of categories of information sharing make up the Tool Kit’s Framework": "Category One: Information Sharing for Purposes of Individual Case Planning and Decision-making"; "Category Two: Data Collection and Sharing for Law, Policy, and Program Development; and "Category Three: Data Collection and Sharing for Performance Measurement and Program Evaluation;". Each category contains these sections: federal law overview; state law; interactive scenarios—sets of questions for testing ones knowledge about information/data sharing with accompanying answer keys; principles—"a set of core principles or positive values that should undergrid all information/data collection and sharing projects"; guidelines—a step-by-step process for developing and implementing such a project including related tools that can be used in the guidelines establishment; and case studies.
