The aim of this research was to measure the impact of a training programme in improving the vocational decision making skills for 10th grade female students in AlBatinah region in Oman through testing the following hypothesis: There is a statistical significant difference at level 0.05 between the experimental group and the control group in making vocational decision attributed to the training programme. The sample of this study consisted of 63 female students of 10th grade. Students were randomly assigned into two groups: an experimental group including (31) female students and a control group including (32) female students. To exmain the study's hypothesis, a training programme was designed and it consisted of ten sessions. This programme's activities were based on Holland's vocational types theory. Each training session ran for 90 minutes. The Crits standard, figure (B1), of taking vocational decision was applied to the experimental and the control groups to compare their performance in the pre and post tests. After collecting data, analytical statistical methods revealed the following result: There are statistical significance differences at the level of 0.05 between the experimental group and the control group in making vocational decision that is attributed to the training programme. In the light of the results of this study, training courses should be organized for raising the student's awareness about vocational choice and appropriate methods should be used for discovering their vocational tendencies. Vocational Direction programmes need to depend on activities derived from Holland's hypothesis of Vocational Types as they are helpful for students in discovering themselves enhacing their vocational exploration. The current programme used in this study can be distributed and applied to all schools in Oman.
