Curriculum Content

The TAB curriculum covers the following:

Instruction Style

Lessons are interactive, using large and small group activities, and brainstorming. The power of TAB comes from the way the program becomes, through conversation, specifically relevant to participants’ lives.

TAB is taught by peers to their communities. This makes the TAB message powerfully relevant and easily replicable in diverse settings since trainers are of the culture in which they teach. Each group walks away from that experience with a changed and empowered vision of an individual’s role in creating a supportive and engaged community.

Minimum number of participants is 10 people. TAB is appropriate for anyone 12 years old and older.

Types of training

TAB uses a Training for Trainers model (T4T). This promotes leadership and supports broad and rapid implementation in which thousands are trained annually. TAB is easily replicable in different cultural and age-diverse settings because trainers are of the culture in which they teach.

During this day-long in-person session, or three-hour sessions over three days in virtual training, those who have participated in the 2.5-hour workshop learn to facilitate it. In pairs, facilitators can then teach the workshop paired with any other trained facilitator.

Particularly talented and experienced TAB trainers are invited to become Instructors, people who work with Quabbin Mediation to train TAB trainers.

The six-unit training builds on the concepts introduced in the 2.5-hour seminar. We define harm doing, the factors inhibiting bystanders from taking action against harm; the factors, including moral courage, which promote active bystandership; and the effects on the target, the harm doer, other bystanders and the community when bystanders do (or do not) interrupt harm doing. Participants practice skills through exercises, role plays and large and small group discussions. Trainees receive a TAB Handbook with unit Information Sheets.

This first-level advanced, four-unit curriculum reviews TAB concepts and analyzes them using current and historical events. For example, one lesson examines the efforts to stop lynching in the U.S., showing the positive evolution of values over 100 years.

This second-level advanced curriculum focuses in depth on targeted populations (for example, people with different abilities, gender identity, transgender, sexual orientation, race, class, size, etc.), discusses why they are targets, and how to intervene.

The basic TAB curriculum is available in Spanish.


This specialized TAB curriculum teaches youth facing significant challenges how to teach TAB to their peers. Staff is also available to teach the specialized Basic curriculum.

The elementary curriculum is for grades 4-6. The curriculum is developmentally appropriate and introduces concepts they will revisit as they move through elementary and secondary school.

TAB has been taught at MIT and Mt. Holyoke College, and in many community colleges, to undergraduates, graduate students, professors and administrators. In community colleges, where the students often have job and family responsibilities, and some are the first in their families to attend college, student retention is a concern. Students feel a greater sense of belonging and feel safer after the introduction of TAB. A number of TAB trainers, on graduating high school, continue as adult trainers.

TAB has been implemented as a means of transforming the workplace to a norm in which harm doing is not acceptable. Active bystandership, in response to harmful actions, leads to more positive interactions among people. It creates an improved workplace atmosphere where all employees feel safe. This contributes to workplace productivity.

TAB promotes collaborative team building skills, engenders a sense of competence, strong leadership skills, and a sense of commitment to the organization. The program substantially reduces costs for conflict management, mediation or litigation.

TAB has been taught at the Massachusetts Correctional Institute in Norfolk to 70 members of the Lifers’ Group in that prison. It has also been taught in the minimum security section of the Franklin County (MA) House of Corrections to 60 inmates slated for transition back to the community.
