What University of Arizona Cooperative Extension Is
Cooperative Extension is the outreach arm of the University of Arizona's College of Agriculture, Life and Environmental Sciences. According to the Extension local offices page, it has offices in all 15 Arizona counties and five Native American nations, and its experts live and work in the communities they serve. The State Administration Office is in Tucson. For most families and producers, though, the office that matters is the one nearest you.

4-H in Arizona
The Arizona 4-H pages describe kids and teens completing hands-on projects in health, science, agriculture and civic engagement with guidance from adult mentors, and say enrollment is handled through local Cooperative Extension offices. Details vary by county, so treat the Mohave County instructions below as an example rather than a statewide rule.
Per the Join Mohave County 4-H page:
- Cloverbuds are 5 to 7 years old and members are 8 to 18. Eligibility is based on age as of January 1 of the 4-H club year, and the youth must not turn 19 by then.
- The 4-H year runs October 1 to September 30.
- A $20 program enrollment fee is due each year.
- You pick a club and contact its leader, then create a profile and enroll as a member in ZSuite.
- To stay in good standing, members need 75 percent club attendance, a demonstration at the club or county level, participation in at least one county staff or Project Director event before the County Fair, an exhibit in each project, and an up-to-date record book at year's end.
The Cloverbud page says Cloverbuds are the youngest youth served by 4-H clubs and take part in a non-competitive space. To enroll, contact a county or tribal Extension office; each office's webpage has a map of local clubs.
Where 4-H Takes Your Kid
A club project often ends at a show. Arizona Extension lists events such as the Arizona 4-H Stock Show and Roundup, scheduled January 30 and 31, 2027 at the Pima County Fairgrounds in Tucson, and the Pinal County 4-H Fair, held March 18 to 22, 2026 at the Pinal County Fairgrounds. Small stock exhibitors have the Colorado River 4-H Small Stock Show in Parker, held January 17 and 18, 2026. See our county fairs guide for how these shows work.
Extension also runs programs for specific projects. The 2026 Cochise County BeefBuilder program asks youth to enroll in a livestock club, apply by April 1, pay a $125 project fee by June 1 and attend every mandatory meeting, with scoring based on site visits and a finish at the county fair.
Help for Producers and Gardeners
Extension is not only for kids. The Yavapai County office, for example, runs a Master Gardener program and supports the county fair's flower and vegetable classes, per its county fair article. It also offers a Zoom-based home horticulture class, a condensed version of Master Gardener training, on Thursday evenings from September 17 to October 29. County agents and specialists handle crop, livestock and natural resource questions in other counties as well. A good first step is to call your county office, describe the problem and ask who handles it.
Native American Nations
Extension lists offices on the Hopi, Hualapai, Navajo, San Carlos Apache and Colorado River Indian Tribes lands. Navajo Nation events include the Navajo Nation Junior Livestock Show and Sale in Window Rock, which asks livestock tags to be requested from the Window Rock Extension office. Call the office listed above for current programs.
How to Get Started
- Find your county office in the directory above and call it.
- Ask for the 4-H contact if you have a child, and ask which clubs are accepting members.
- Ask what the enrollment fee is, since Mohave lists $20 and other counties may differ.
- Ask about quality assurance training, ownership dates and fair deadlines before you buy an animal.
- Bring producer, garden or land questions to the same office and ask who handles them.
