Outdoor skills are critical to the success of the Scouting and Venturing programs. Introduction to Outdoor Leader Skills (IOLS) will provide leaders with the basic outdoor skills information needed to conduct a safe and well-prepared program. IOLS is the required outdoor training for all Scoutmasters and Asst. Scoutmasters. The skills taught are based on the outdoor skills found in The Boy Scout Handbook and are taught in an outdoor setting.
