There are several deficiencies inherent in this method of training, however. Some of these deficiencies are the lack of a standardized course of instruction, the inability to evaluate the quality of the training received by an individual, the absence of any criteria establishing minimum levels of competency, and the length of time required which results in a reluctance to hire trainees. These and other shortcomings in on-the-job training are discussed in view of a survey that was conducted of 249 document examiners associated with the Federal, State, county, local, and private laboratories. Some possible remedies to correct the weaknesses in the current approach to training are offered. (Author abstract)
