Part IV of National Employment Service Manual specifies that in order to carry out effectively the selective placement of the handicapped the following points have to be borne in mind:-

  1. The worker must be able to meet the physical and mental requirements of the job;

  2. He must not be a hazard to himself;

  3. He must not jeopardize the safety of other;

  4. The job must not aggravate the disability. Sometimes, it may be necessary to arrange with an employer for a slight modification to be made to suit an individual handicapped person, e.g., re-arrangement of tools or the provision of a simple seat. Ideally, any such adjustment should be made before the employment starts, to avoid leaving the person concerned with a feeling that he has failed to match up to the requirements of the job.
