RESEARCH SOUGHT TO (1) IDENTIFY CRITERIA USED BY DIRECTORS OF PUBLIC SCHOOL ADULT EDUCATION PROGRAMS IN SELECTING THEIR TEACHERS FOR INSTRUCTION IN VOCATIONAL, AVOCATIONAL, CULTURAL, AND ACADEMIC SUBJECTS, (2) VALIDATE SPECIFIC CRITERIA OF SELECTION AND (3) TEST THE CRITERIA. A QUESTIONNAIRE TECHNIQUE IDENTIFIED NINE VALID TEACHER SELECTION CRITERIA WHICH COMPOSED THE TESTING INSTRUMENT SENT TO STUDENTS ENROLLED IN PUBLIC SCHOOL ADULT EDUCATION PROGRAMS IN NASSAU COUNTY. ADDITIONAL DATA ON RATED TEACHERS WAS GATHERED TO COMPARE THOSE WHO HAD TRAINING AS TEACHERS OF YOUTH AND THOSE WHO HAD NOT. THERE WERE NO SIGNIFICANT DIFFERENCES IN THE NINE CRITERIA OF SELECTION AMONG THE TWO GROUPS OF TEACHERS. IT WAS CONCLUDED THAT TEACHER CERTIFICATION FOR TEACHING OF YOUTH IS AN INDEFENSIBLE CRITERION FOR SELECTION OF PUBLIC SCHOOL ADULT EDUCATION TEACHERS, THAT NASSAU COUNTY IS TERMINATING A RAPID PERIOD OF GROWTH, AND THAT EXPANSION OF PUBLIC SCHOOL ADULT EDUCATION WILL CONTINUE AT A REDUCED RATE. THE DATA ALSO INDICATED A WIDE DIVERSITY OF OPINION AMONG DIRECTORS OF PUBLIC SCHOOL ADULT EDUCATION PROGRAMS ON THE CRITERIA USED FOR SELECTING TEACHERS.
