Adult:child ratios are closely related to small group sizes. (See 45 CFR §1302.21(b)(1)-(2) and 45 CFR§1302.23(b)(1)-(4).) Studies show that low adult:child ratios and small groups “are consistently correlated with more frequent, more playful, and warmer interactions between adults and children, more positive interactions between children, better overall environments for learning, and better outcomes for children.”[2]
Note that small caseloads let home visitors focus attention and services and individualize home visit planning for each child and family (45 CFR §1302.22(b)).
