4Hs

The 4-Hs, or 4-H, is a framework associated with the 4-H movement that emphasizes four areas of youth development: Head, Heart, Hands, and Health. The four domains guide program design, learning activities, and the organization’s pursuit of personal growth. The emblem commonly associated with 4-H is a green four-leaf clover with a white H on each leaf.

Originating in the United States in the early 20th century, the 4-H movement grew from agricultural extension programs aimed at rural youth. The concept of developing Head, Heart, Hands, and Health became a central organizing principle for volunteer leaders, educators, and clubs. The 4-H pledge, reaffirming commitment to clear thinking, loyalty, service, and healthier living, is often linked to the movement.

Activities across 4-H programs center on hands-on, experiential learning in fields such as science, technology, engineering, agriculture, citizenship, and healthy living. Projects are typically youth-led with adult mentoring and involve community service and leadership development.

Today, 4-H operates in many countries beyond the United States. Programs are delivered through government extension services, universities, and non-profit organizations, adapting the core Head–Heart–Hands–Health framework to local cultures and educational systems.
