In 1993; the ASCP Board of Registry began a 10-year prospective study of th
e career patterns of 412 newly MT(ASCP)-certified persons. The Board examin
ed the changes in core, advanced technical, and management job tasks of the
se MTs during their first 5 years of work. In the first year, the MTs did c
ore tasks more frequently than advanced technical or management tasks. Five
years later, they still did core tasks frequently and had acquired additio
nal advanced technical and management tasks. The entry-level task mix of MT
s was the same regardless of gender, ethnicity, job title, facility locatio
n, or degree.
