Abstract
This research aims to assess the effectiveness of the in-service teacher training programme in Palestine, based on the opinion of the teacher participants in order to improve future in-service programmes. The Spearman's coefficient of rank correlation p test has been used to examine the stated null hypotheses. It indicates that the participants considered the concept of planning a lesson plan as the most important competency. The research found that there is a positive association among all groups of teachers (except onc group) concerning the importance of the listed objectives of the in-service programme, at a significant level of .05. Finally, the study recommended that in-service teacher programmes should place more emphasis on class applications and teaching techniques using different training programmes.
