Healthy Relationships, Consent & Self-Defense for Teens
9 hours, 6 Online Sessions, Open to girls, women, nonbinary & LGBTQ people ages 14-22
Course Fee: Sliding Scale $85–175

Quotes from students:

What does a healthy relationship look like? How do you know your limits? How do you communicate them to people in your life?

This online class teaches teens a range of skills for staying safe and sane as they navigate dating, relationships, friendships, life changes, and the uncertainty of the pandemic. Designed for our new digital reality, teens will get the opportunity to practice physical and verbal self-defense skills, assertive communication and bystander intervention. They will also engage in critical discussions that help them define what they want out of relationships and how to advocate for themselves. By the end of the course, students will have a clearer vision of how to take control of their lives and take care of themselves during & beyond the pandemic.

Students Gain:

  • Social context for violence and how to prevent it
  • Risk assessment tools when they detect threats to emotional & physical safety
  • Understanding of healthy relationships & their own limits
  • Verbal & physical strategies to handle unsafe situations
  • Strategies for intervening as a bystander
  • Confidence in their ability to ask for what they want

Students who took this course online said:

“I expected that this class would be primarily focused on physical skills, but this class offered me just as much mental growth. I feel much more ready for future relationships in multiple ways, including being clear and direct with others… I think that this will really contribute to my confidence in college.”

“The most helpful part of this class were the discussions. If this class was only learning physical moves I don’t think I would have gotten as much out of it as I have. Because we had lots of discussions and worked together in small groups I felt that we also made a stronger class community. The online platform was great and I really enjoyed it.”

Find your courage and use it to make the world around you safer.

At IMPACT we believe everyone has the right to be safe and the ability to protect themselves. Our self-defense programs give people the skills to stay calm and focused in unsafe situations. Our abuse prevention programs give schools, disability service organizations, and communities the tools to develop policies and expectations that keep everyone safe.

IMPACT offers:

  • Self-defense classes that are open to the public.
  • Customized workshops for schools, disability service organizations, community groups, businesses, human service agencies, and domestic violence and sexual assault survivors that cover topics in:
    • Abuse prevention
    • Self-defense
    • Assertive communication
    • Conflict de-escalation

Personal and social change are possible when people experience the strength of their bodies and the power of their voices.

Working for Safer Communities

Many communities are experiencing harassment and violence in the current political climate. Many others are feeling a sense of urgency to speak up and show solidarity and support for neighbors, friends, and even strangers.

At IMPACT we believe that keeping ourselves safe and advocating for others go hand in hand. We are committed to giving community groups and individuals the tools to safely intervene when someone else is at risk. This means having the skills to protect your own safety and manage your own stress response in the moment of violence or harassment.

In the past few months we’ve taught bystander skills in mosques, Unitarian churches, community centers, and our own training center. We’re committed to reaching individuals and communities with these necessary tools.
