Implementing the Massachusetts Arrest Screening Tool for Law Enforcement
If the police department decides to use the MASTLE, it will be essential to maintain the MASTLE data (the completed screening tools with youth information)
in an electronic system or other form
of record keeping. Therefore, before adopting this screening tool, police administrators should have the following
items in place. Please check the items below that you have in place.
A standard policy for data collection is established which includes youth arrest records and previous defaults.
The standard includes conditions for confidentiality and privacy as required by law.
Data collection procedures are in place to store and maintain information.
Law enforcement agency maintains confidential records management (for police use only).
There is administrative oversight of arrest proceedings.
There are qualified Officer’s In Charge who can be trained to complete the MASTLE and provide instruction to other officers.
Before adopting this screening tool, police administrators are strongly encouraged to consider the following items. Please check whether the following procedures and practices are already in place. Please note that your responses to this section do not affect our ability to give you the MASTLE.
Transport of Juvenile Prisoner Policy.
Alternative lock up facilities.
Understanding and compliance of responsibilities under Federal JJDP Act.
A means of encouraging family involvement with police.
Have a system in place for regular evaluation of the MASTLE to determine if the cutoff scores appear to be appropriately identifying Low, Moderate, and High risk youth in your population.
Approval and support from local leadership (Mayor, Manager, or Selectman) for youth diversion.
Implementing a Law Enforcement-Based Diversion Process for Youth:
The MASTLE’s benefits will be maximized if it is part of a larger diversion process. One comprehensive resource about putting together a model diversion process or program for youth can be found on
MacArthur Foundation’s Models for Change website – Juvenile Diversion Guide Book http://www.modelsforchange.net/publications/301
I, Please Type Your Name:
, agree not to modify the actual items of the Massachusetts Arrest Screening Tool for Law Enforcement (MASTLE) without written permission of the authors. I understand the cut off scores for the total score can, and possibly should, be modified based on results in my jurisdiction.
I also agree not to disseminate the MASTLE, including postings to websites, as the MASTLE is copyrighted and should only be disseminated by the developers.
I also agree to provide a de-identified dataset of the MASTLE screening tool items and youth demographics if requested by the developers and if the required data-sharing agreements and protections are put in place. This is solely so the authors may use the data to refine and norm this screening tool.
The parties hereby agree that either an electronic signature or your typed name in the space
provided for "Your Signature" is an acceptable, signed authorization
THANK YOU FOR YOUR REQUEST!
