Sometimes known as task-shifting—is the systematic delegation of tasks, where appropriate, to less specialized workers in order to maximize the efficient use of resources.
Task-sharing involves training mid- and low-level cadres of health workers—such as clinical officers, auxiliary nurses, and CHWs—to deliver some services offered by higher-level cadres in order to optimize the reach of a limited health workforce.
