Food Production -- Knowledge of techniques and equipment for planting, growing, and harvesting food products (both plant and animal) for consumption, including storage/handling techniques. Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance. Biology -- Knowledge of plant and animal organisms, their tissues, cells, functions, interdependencies, and interactions with each other and the environment. Building and Construction -- Knowledge of materials, methods, and the tools involved in the construction or repair of houses, buildings, or other structures such as highways and roads. Chemistry -- Knowledge of the chemical composition, structure, and properties of substances and of the chemical processes and transformations that they undergo. This includes uses of chemicals and their interactions, danger signs, production techniques, and disposal methods.

Operation and Control -- Controlling operations of equipment or systems. Equipment Maintenance -- Performing routine maintenance on equipment and determining when and what kind of maintenance is needed. Repairing -- Repairing machines or systems using the needed tools. Operation Monitoring -- Watching gauges, dials, or other indicators to make sure a machine is working properly. Equipment Selection -- Determining the kind of tools and equipment needed to do a job. Troubleshooting -- Determining causes of operating errors and deciding what to do about it.

Static Strength -- The ability to exert maximum muscle force to lift, push, pull, or carry objects. Multilimb Coordination -- The ability to coordinate two or more limbs (for example, two arms, two legs, or one leg and one arm) while sitting, standing, or lying down. It does not involve performing the activities while the whole body is in motion. Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions. Dynamic Strength -- The ability to exert muscle force repeatedly or continuously over time. This involves muscular endurance and resistance to muscle fatigue. Manual Dexterity -- The ability to quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects. Trunk Strength -- The ability to use your abdominal and lower back muscles to support part of the body repeatedly or continuously over time without 'giving out' or fatiguing. Gross Body Coordination -- The ability to coordinate the movement of your arms, legs, and torso together when the whole body is in motion. Explosive Strength -- The ability to use short bursts of muscle force to propel oneself (as in jumping or sprinting), or to throw an object. Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations). Arm-Hand Steadiness -- The ability to keep your hand and arm steady while moving your arm or while holding your arm and hand in one position.

Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials. Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles. Operating Vehicles, Mechanized Devices, or Equipment -- Running, maneuvering, navigating, or driving vehicles or mechanized equipment, such as forklifts, passenger vehicles, aircraft, or water craft. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Estimating the Quantifiable Characteristics of Products, Events, or Information -- Estimating sizes, distances, and quantities; or determining time, costs, resources, or materials needed to perform a work activity. Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events. Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems. Organizing, Planning, and Prioritizing Work -- Developing specific goals and plans to prioritize, organize, and accomplish your work. Inspecting Equipment, Structures, or Material -- Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects.
