*This improvement initiative was under the supervision of TAMAM Steering Team.
The aim of the study is to gain empirical evidence for the benefits of teachers that they get from professional days. In addition, the team worked on the impact of those PDs regarding the overall climate of the school. The tools used are mainly interviews, trainees’ questionnaires, student ushers questionnaire, and evaluation forms. The results of the study came to show that PDs seem to be providing trainers with the opportunity to explore most recent and up-to-date theoretical and practical issues regarding the teaching/learning process. The next step would be to start questioning the impact of the PDs on the performance of teachers inside classrooms and its positive effect on students’ achievement.
