Vital allies from the beginning were the Athol-Royalston Regional School District, the Athol Police Department, Ralph C. Mahar Regional School District, and the Orange Police Department. We have trained over a thousand student TAB trainers and hundreds of community adults trainers who have taught over ten thousand youth and adults to analyze a situation when they are bystanders to harm and to safely take action. The original version of the Training Active Bystanders curriculum was created and first used in collaboration between Quabbin Mediation, Inc. and Professor Ervin Staub in 2006-2007 and is based in significant part on his work.
