In our Troop we firmly believe thaty every Scout deserves a trained leader. The Boy Scouts of America (BSA) national office has developed training requirements, and several online courses to assist in this training, and local councils carry out in person training as well.
BSA training requirements are available here.
Every adult member of the Pack or Troop is required to complete Youth Protection Training (YPT). This is an online course available at my.scouting.org.
