Adm<strong>in</strong>istrative Procedure CC070:On the Job Tra<strong>in</strong><strong>in</strong>gON-THE-JOB-TRAINING Approved by: ASW:PHV:ETEffective Date: 05/08/96Revision Date: 10/24/08Adm<strong>in</strong>istrative: CC070I. PRINCIPLE:To assure that all technical staff are adequately tra<strong>in</strong>ed, an on-the-job tra<strong>in</strong><strong>in</strong>g program (OJT) hasbeen developed. This procedure outl<strong>in</strong>es the steps <strong>in</strong>volved.II. PROCEDURE:A. The Laboratory Director will assess all technical employees at the time of employment for theirsuitability to perform cl<strong>in</strong>ical test<strong>in</strong>g. Individuals with appropriate education and professionalcertification will then go through <strong>Microbiology</strong> Specialists Inc. OJT.B. msi OJT consists of mastery of multiple tasks as outl<strong>in</strong>ed <strong>in</strong> this SOP. The program beg<strong>in</strong>s with theaccession<strong>in</strong>g and set-up of specimens and the performance of direct exams. The entire process cantake 3-5 years.C. Day shift jobs are divided by benches. Each bench (Bacteriology, Virology, Mycobacteriology,Mycology, Parasitology, Molecular, and Special Studies) has a general list of tasks. Because of theextensive list of procedures, tra<strong>in</strong>ers and tra<strong>in</strong>ees are referred to procedure manuals for each bench.
