Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining a likelihood that an individual is ready. The methods, systems, and apparatus include actions of obtaining health data for a set of individuals, providing the health data for the set of individuals to a readiness classifier that classifies individuals as either ready or as not ready, obtaining, from the readiness classifier, classifications for each of the individuals of the set of individuals, generating, from the classifications for each of the individuals of the first set of individuals, a readiness risk scoring model that determines a risk that an individual is not ready from health data of the individual, obtaining health data regarding a particular individual, and determining, from the health data regarding the particular individual and the readiness risk scoring model, a risk that the particular individual is not ready.
