This resource provides an Excel-based calculator that allows states to make several comparisons related to the percentage of infants and toddlers served: State percentage compared to state target, local program percentage compared to state target, and year-to-year comparisons of the state percentages. It also computes confidence intervals to determine whether the difference between the two numbers is large enough to be considered meaningful (i.e., statistically significant).
