This study aimed to investigate the levels of teachers' reflective practices as well as their attitudes toward professional self-development in relation to various variables, including gender, number of workshops attended and experience. The study sample consisted of 162 teachers who work as teachers at a number of private schools in Amman. Two scales have been used in this study; the first questionnaire consists of (28) items to measure teachers' reflective practices in 6 dimensions. The second scale consists of (18) items to measure the attitudes-towards-professional-development. Results found that the level of teachers' reflective practices on the scale as a whole were within an 'acceptable' level; however, their practices in the subcategory of"appreciating criticism" were below acceptable. Findings indicated that teachers' attitudes toward professional development were positive. Findings further revealed a strong correlation of 0.485 between the reflective practices and the attitudes toward self-development in teachers.
