In the DOT coding system, what do lower numbers indicate about functional demands?

In the Dictionary of Occupational Titles (DOT) coding system, lower numbers correlate with lower levels of complexity in functional demands. This system classifies various jobs based on the skill and complexity required to perform them. As the numbers increase, they typically represent job categories that require higher levels of skills, cognitive abilities, and problem-solving.

In the context of functional demands, a lower number would indicate less complexity. It signifies tasks that may require minimal training, simpler decision-making processes, and reduced cognitive demands. Each movement up in the numerical scale generally signifies a corresponding increase in job complexity and the requisite skills needed to perform those tasks effectively. Thus, lower numbers in the DOT system reflect less complexity in functioning associated with various occupations.
