The mission of PH is to create conditions in which all
people can be healthy. To accomplish this very broad
mission, multiple disciplines are required to meet the
needs of local populations within a local task environment.
Yet, within PH’s mission there are well-recognized common
core functions: to assess population health needs and
develop policies to ensure these needs are met.10 In this
respect, there is a basis for commonality in PH work and
thus some degree of TKR congruence within job classes.
