The MASTLE assesses the likelihood a youth taken into police custody for a criminal offense will be arrested for the commission of another offense in the future or will fail to appear for arraignment. The applicable risk factors are rated and “added up” into a total “risk” score. The higher the score, the greater the risk for rearrest or failure to appear for arraignment. This information will allow police supervisors and commanders to conserve resources by making research-informed pre-processing decisions; such as, whether to hold youth in pre-arraignment detention at the police station or divert youth away from formal arrest.
