^A Wisconsin state eligibility criteria for early intervention due to developmental delay is determined by performance on a standardized developmental evaluation that is more than 1.5 standard deviations below the mean.
^B Neighborhood disadvantage categories were created from an overall neighborhood disadvantage index (combining maternal education, poverty, single-family households, maternal unemployment, and incomes below state median each collected at the Census tract level; higher scores indicate more disadvantage) to correspond to disadvantaged (highest tertile), moderate disadvantaged (middle tertile), and advantaged (lowest tertile).
^C Severity of Neonatal morbidity is measured using the Score of Neonatal Acute Physiology (SNAP-II, range 0–115). Higher scores indicate more severe morbidity.
^D Functional skills were measured by the Pediatric Evaluation of Disability Inventory (PEDI). The PEDI is a norm-referenced developmental assessment tool with a mean of 50 and standard deviation of 10. The PEDI meets Wisconsin mandates for a developmental tool appropriate for determining eligibility for EI services.
