South Dakota State University (SDSU) Extension 4-H will be hosting county fairs and achievement days across South Dakota starting in July 2026.
In 4-H, youth design and participate in their own projects and related activities. This unique learn-by-doing model teaches essential skills that youth will use throughout their lives, such as identifying interests, desiring knowledge, setting goals, engaging in self-reflection, adapting to new situations, communicating and responding to the needs of others. Whether a young person builds a rocket, raises a companion pet, or plants vegetables, 4-H gives youth the skills they need to thrive and succeed throughout their lives.
Visit the State Fair page for score sheets, forms and educational resources.
