To determine the extent to which differences in occupational and geographic mobility are a result of the learning environment in which a certified electronic technician was trained, and to disclose the differences resulting from the occupation itself, the entire population of over 1,500 certified engineering technicians in New York, New Jersey, and Pennsylvania were surveyed by questionnaire. The results showed great similarity among technicians from different training environments and from different areas of specialization. Differences in geographic and occupational mobility were unrelated to learning environment for all classes of technicians. (BH)
