"This report presents the results of a study to determine the extent to which written materials used in training railroad tank car hazmat loaders are consistent with the reading skills of the trainees. Data from four case study sites was used to conduct the analysis. Each site trains employees to load hazardous materials into railroad tank cars. The reading level of the trainees was assessed through self-reporting of years of education completed and through the administration of a verbal skills aptitude test. The Fry Readability Index was used to determine the reading level of the written training materials from each site. Each program had some degree of incompatibility between the reading level of the materials and the skills of the trainees. Suggestions are offered for individual companies that want to examine their programs for possible incompatibility. In addition to presenting the results of this analysis, the report contains guidelines and best practices for this type of training. An appendix contains guidelines for preparing written materials for adults with limited reading skills."
