- Overall, for both the young children in the COS sample and the school-age children across all evaluation sites, program impacts on child development were as likely to be favorable as unfavorable.

As previously noted, however, favorable impacts were concentrated in the area of cognitive development and the few health impacts found were unfavorable. Similarly, for school-age children in all 11 programs, there was an almost equal mix of favorable and unfavorable impacts. (See Table 6.)
