Do you agree or disagree that Universities and colleges should provide students with work preparation before they graduate.

The tertiary education has long been center of public attention. It has been argued that schools should advocate a work preparation to the graduate before entering the society. From my perspective, I agree.

Firstly, work preparation enables students to win edge over other competitors in job market. The preparation will allow students shift the role smoothly from college to society by foreseeing the occupational issues relevant with code of conduct, skills in the interview and so on. According to a recent survey conducted by CASS(Chinese Academy of Social Science), after polling hundreds of staffs from human resource department of transnational enterprises, most respondents claimed that a candidate who has acquired a good knowledge of vocational preparation is always more competitive to get the position than another who shows the same good performance at school but has nothing beside the textbook. Thus to some extent, the professional preparation is instrumental for a graduate in the job interview.

Secondly, high employment rate is beneficial to the university's reputation. An university’s most valuable characteristic is its reputation. Naturally, by publishing a nearly hundred percent employment rate on the homepage of its website, not only do the college enhance the position in higher educational ranking, but it also boost the enrollment of new session because of the poweful attraction. It is hard to imagine students from a prestigious university will wander around their early twenties, paying rent, reading classifieds and wondering why the lights were not turning green for themselves. So at times like this preparation dose matter.

Thirdly, well-prepared students allow companies to cut training fees. A freshman who suffer the shock of culture of enterprise would impose financial burden on employee's training includes code of conduct. My older brother is a good case in point. He used to attend a class aimed at job preparation for graduate. After the training, he almost fostered the social skills and traits which would build up the sense of belonging with his later admirable company. Without a empolyee's training, his boss afford him a costly course in MBA(Mater of Business Administration) using the original fees of training. It was a big deal of money that spends on training fees. It seems clear to me that well-preparation enable the companies to save a lot of fees.

All in all, consider the benefits on individuals, universities and companies, it is indispensable to give work preparation for students before graduation.
