For this followup study an attempt was made to retest all 136 children evaluated in the Austin, Texas Day Care Program nine months earlier but only 95 children were available. Subjects were Negro and Mexican-American. The original study indicated that significantly higher scores were earned on tests of intellectual performance as a function of length of time in program and that "old" children (in program approximately 14 months) gained as many as ten IQ points over "new" children (in program an average of 3 months). Were the old children brighter to begin with or did they have parents more intellectually alert to the benefits of continued participation? To answer this question 57 old children and 38 new children were retested with two well-known, individually administered intelligence tests. Results indicate that those who had been in the program an average of 23 months were to some extent brighter and that upon retesting a slight but significant drop in intellectual level occurred on the Binet. The new children, however, made slight gains between the original and the followup testing which upon closer analysis might be dismissed as artifactual. Differential effects for sex and ethnicity occurred. Five other questions about the relationship of intellectual development to day care are raised by this study and remain unanswered.
