The study aimed to identify the effectiveness of a proposed training program for developing action research skills among female mathematics and science teachers in the Kingdom of Saudi Arabia. The study employed a semi-experimental approach with a one-group design and pre- and post-measurement. A sample of 36 female mathematics and science teachers from the Bisha Education Department took part in the training program and then took a test to evaluate their action research skills. The results revealed statistically significant differences in the teachers’ action research skills at the level α ≤ 0.05 between the pre- and post-measurements in favor of the latter. In light of the study results, some recommendations can be made: A culture of action research should be fostered among male and female teachers in general and in mathematics and science teaching specifically; research partnerships should be built to include experts and male and female teachers in general education; male and female teachers should undergo training to develop action research skills.   Received: 12 January 2023 / Accepted: 23 February 2023 / Published: 5 March 2023
