  • Find ways to make roller derby announcing more inclusive, especially at WFTDA Tournaments and Events

Some of the curriculum presented during the course will include:

  • Navigating WFTDA statistics
  • Coaching and gameplay strategy at Playoffs and Championships
  • New broadcast techniques and sideline reporting
  • Facebook Live and other digital tools
  • Vocal range & camera presence
