As computer-related programs are introduced into school curricula, it is helpful to evaluate student attitudes which may affect the success of such programs. This study, involving 155 eighth-through twelfth-grade students, examines the reliability and factorial validity of the Computer Attitude Scale and its three subscales (Computer Liking, Computer Confidence, and Computer Anxiety). The data suggest that this instrument is an effective, reliable, and convenient means of measuring student attitudes toward learning about and using computers.
