Of the five exemplar job classes we examined, four have a
small proportion of positively congruent TKRs, numbering
only between 15 and 35 (11%–23%), suggesting that scope
and specialization of these job classes is not well defined
relative to essential PH work. The exception is the PH
Agency Director, which has 113 (75%) positively congruent
TKRs, suggesting the broad capability and range of skills
and knowledge necessary at the level of agency leadership.
