Wool judging offers an excellent opportunity for youth in 4-H or FFA to become proficient in a judging contest that is conducted at the collegiate level. Collegiate teams are comprised of predominantly freshmen students. Recently Texas Tech teams have been extremely successful, winning four Co-National and a National Championship in the past six years.
