Universities training teachers have a responsibility to select the best applicants for pre-service teacher training. This study examines the validity of the Human Relations Incident (HRI), an instrument designed to predict the effectiveness of pre-service applicants. High and low scoring subjects were selected based on their HRI scores. Their teaching effectiveness was assessed by analysis of faculty practicum reports and, in a longitudinal study, through observation, self-report, and student evaluation during their first teaching years. High scorers exhibited more effective teaching behaviors during practicum such as appearing confident, being imaginative, showing respect, being flexible, showing commitment to teaching, and having good communicative skills. As beginning teachers, HRI high scorers also tended to score consistently high on a systematic observation instrument. Longitudinal study significance was seriously affected by subject attrition due to government changes in educational funding which resulted in very few subjects being hired to teach. Further research, using a case study approach, was recommended to confirm the findings. The report contains the HRI instruments. The perceptual rating scale, behavior checklist, profile of teacher behavior observation form, and two student evaluation instruments are appended. (Author/BS)
