ASSESSMENTS OF ASTRONAUT EFFECTIVENESS

This study examined the reliability and convergent validity of three m ethods of peer and supervisory ratings of the effectiveness of individ ual NASA astronauts and their relationships with flight assignments. T hese two techniques were found to be reliable and relatively convergen t. Seniority and a peer-rated Performance and Competence factor proved to be most closely associated with flight assignments, while supervis or ratings and a peer-rated Group Living and Personality factor were f ound to be unrelated. Results have implications for the selection and training of astronauts.
