The purpose of this study was to develop a set of procedures to establish readability, including an equation, that accommodates the multiple-choice item format and occupational-specific language related to credentialing examinations. The procedures and equation should be appropriate for learning materials, examination materials, and occupational materials. To this end, variance in readability estimates accounted for by combinations of semantic and syntactic variables were explored, a method was devised to accommodate occupational-specific vocabulary, and new-model readability formulas were created and calibrated. Existing readability formulas were then recalibrated with the same materials used to calibrate the new-model formulas. The new-model and recalibrated formulas were then applied to sample items extracted from a professional licensing examination and the results were compared.
