The significant difference(MD10.48;p0.001) between core communication skills ineighth-andsecond-semester students depicted the improvement through the periods of instructions.The report by Middleton(2003)on the high command of communication in LIS graduate students was inagreement with the current study findings.A study by Buttlar and DuMont(1996) showed that the ability to use verbal skills in presentations is among one of the competencies needed for novice and expert librarians alike and, although employers prefer to hire people with soft skills,such as communication skills, such skills are not taught in LIS courses. General skills such as communication skills were among the necessary skills lacking in new LIS graduates in Iran.
