This study was conducted to examine students' perceptions of the impact of age and gender upon an individual's ability to teach. Seventh-grade science students (N=28) were shown photographs of six teachers (a young female, a young male, a middle-aged female, a middle-aged male, an old female, and an old male) for purposes of evaluation in terms of organization, classroom management, motivation, communication, sensitivity, imagination, and competence. Results suggest that students perceive middle-aged teachers and female teachers as more effective in the classroom; there was no significant main effect on students' perception due to the age of the teacher in the areas of motivation, communication, sensitivity, and competence; middle-aged pictures were rated higher than young-aged and old-aged pictures in the areas of organization and imagination; there were no significant main effects due to the gender of teachers in the areas of classroom management, motivation, communication, sensitivity, imagination, and competence; females were rated higher than males in the area of organization; and no significant interaction between the age and gender of the teacher in areas of motivation, communication, sensitivity, imagination, and competence was revealed.
