资料题：According to the passage, which of the following statements is NOT true（　　）。

As we know, it is very important that a firm should pay attention to the training of its staff as there exist many weak parts in its various departments.Staff training must have a purpose,which is defined when a firm considers its training needs, which are in tum based on job descriptions and job specifications.A job description should give details of the performance that is required for a particular job,and a job specification should give information about the behaviour, knowledge and skills that are expected of an employee who works in it.When all of this has been collected, it is possible to make a training specification.This specifies what the Training Department must teach for the successful performance of the job, and also the best methods to use in the training period.There are many different training methods, and there are advantages and disadvantages of all of therm.Successful training programs depend on an understanding of the difference betweenlearning about skills and training in using them.It is frequently said that learning about skills takes place"off the job" in the classroom, but training in using these skills takes place"on the job" , by means of such activities as practice in the workshop.It is always difficult to evaluate the costs and savings of a training program.The success of such a program depends not only on the methods used but also on the quality of the staff who do the training.A company can often check on savings in time and cost by examining the work performed by the workers and technicians who have completed a training program.The evaluation of management training is much more complex than that.
