ACCORDING TO A SURVEY OF ELEMENTARY SCHOOL PRINCIPALS, THE SERVICES OF CHILD DEVELOPMENT CONSULTANTS (CDC'S) HAVE HAD AN IMPACT ON THE DEVELOPMENT OF CHILDREN. ALMOST 13,000 ELEMENTARY SCHOOLS HAD CDC'S IN 1962-63. OF THE PRINCIPALS IN SCHOOLS WITHOUT CDC'S, THREE-FOURTHS EXPRESSED NEED FOR SUCH SERVICES. CDC'S DESCRIBED AS HAVING A BACKGROUND IN PSYCHOLOGY WERE MORE NUMEROUS THAN ANY OTHER GROUP OF BEHAVIORAL SPECIALISTS. ABOUT TWO-THIRDS OF THE CDC'S HAD MASTER'S OR DOCTORAL DEGREES. THE LARGEST PERCENTAGE OF PRINCIPALS REPORTED THAT THEIR CDC'S WORKED MORE WITH CHILDREN THAN EITHER TEACHERS OR PARENTS. CHILDREN WITH EMOTIONAL-SOCIAL PROBLEMS WERE AMONG THOSE RECEIVING THE MOST ATTENTION FROM CDC'S. CONSULTATION WITH PARENTS AND TEACHERS, IN ADDITION TO THE COUNSELING OF CHILDREN, WERE CONSIDERED THE MOST IMPORTANT FUNCTIONS OF THE CDC. THE MEDIAN NUMBER OF PUPILS PER CDC WAS 789. THE MEDIAN NUMBER CITED AS BEING NEEDED FOR ADEQUATE SERVICE WAS 609 PUPILS PER CDC. BECAUSE QUESTIONNAIRES WERE ANSWERED BY PRINCIPALS, THE GUIDANCE PERSONNEL VIEW IS LIMITED IN THIS SURVEY. SAMPLES WERE DRAWN ONLY FROM SCHOOLS WHICH ENROLLED OVER 100 PUPILS. THIS DOCUMENT IS AVAILABLE AS CATALOG NO.
