DESCRIPTION:The history of the Apgar score\, an index of overall infant we
 llbeing just after birth\, can help philosophers understand why instrument
  validation often seems to come short in practice and why clinicians conti
 nue to 'misuse' standardized instruments. I propose extending concerns abo
 ut measurement realization (as being an integral part of epistemology of m
 easurement) to constructs – that is\, construct realizations. This invol
 ves including a new domain for operational coherence – clinical judgment
 s – which themselves have a scale which may differ from the property we 
 believe ourselves to be measuring. When the main purpose of a measuring pr
 actice is to arrive at this kind of clinical judgment\, the scale of possi
 ble judgments (or courses of care) becomes how we experience the outcome o
 f the measuring process itself. From the scale of possible judgments which
  results from measurement outcomes\, we can deduce the construct as it is 
 actually experienced by those involved. To understand measurement validati
 on practices of the past or present\, we must concern ourselves with const
 ruct realization\; that is\, what the construct actually turns out to be a
 s it is experienced by patients\, providers\, and health systems.
