The challenge of low performing schools continues to rear its ugly head in many countries, including South Africa. The responses to low performance differ from country to country, but none of these have included the enhancement of collective teacher efficacy in their repertoire. Research shows that collective teacher efficacy is positively related to improved academic performance of learners. Schools with a higher sense of collective efficacy outperform schools with a lower sense of collective efficacy. Schools with high efficacy are characterised by strong work ethic, and teachers who persist in the face of difficulty. Moreover, teachers in these schools are more persistent in their efforts, plan more, and view failure as a temporary set-back that does not discourage them. Therefore, if principals and their management teams could find a way to enhance collective teacher efficacy, the challenge of low-performing schools may be overcome. In view of this, quantitative research was conducted with the aim of determining the strength of collective teacher efficacy in low performing schools. Ten randomly selected schools in the Kenneth Kaunda Education District were involved in the research and in each selected school all the teachers were involved (N = 217). Data was collected using a questionnaire (The Collective Teacher Efficacy Scale: short version). The questionnaires were delivered and collected in schools by the researchers. Data was analysed using descriptive statistics, frequencies, percentages and mean scores. The results show that collective teacher efficacy in these schools is medium to high pertaining to group competence, but lower in task analysis.
