The evolution of existing technologies and the development of new technologies remain the hallmark features of forensic DNA typing. Diverse DNA procedures have been implemented in many laboratories as a result of demands for efficiency, quality assurance, court testimony and cost-effectiveness. For the past seven years, the Royal Canadian Mounted Police Forensic Laboratory Directorate has met the challenge of training and qualifying personnel in the field of forensic DNA typing through a series of specific workshops and course training standards. To date, 56 people have been trained in 6 laboratories for RFLP casework and 19 individuals given additional training in STR technology. The standard of training with respect to 1) introduction of concepts, 2) application and 3) evaluation, comprehension and performance have evolved from RFLP technology to the present STR fluorescent automated approach used in the RCMP system.

Not all approaches in training are equally successful, and it has been our experience that a series of lecture/tutorials covering the diverse areas of molecular biology, population genetics and forensic DNA testing lay the important foundation. The presentation highlights the experiences of the RCMP and the practical lessons gained for development of an effective training program that is both comprehensible yet flexible. The use of computer graphics, hands-on demonstration, round-table discussions, practical and written exams are assessed with respect to effectiveness and the ability to incorporate change as training requirements are altered.
