In response to a mandate from the California State Legislature, the California Board of Corrections conducted a three-phase research study in preparation for the revision and standardization of the current state standards for hiring and training corrections personnel. This document presents the vision and hearing guidelines for the occupations of corrections officers, juvenile counselors, and probation officers. The first section of the document is a brief description of the job analysis and the methods used to develop the vision and hearing guidelines. A summary of job analysis data for each of the three occupations is given in terms of the following dimensions: for vision--near visual acuity, far visual acuity, visual color discrimination, and peripheral vision; for hearing--sound detection, sound localization, sound recognition, sound discrimination, and speech comprehension in quiet and noisy environments. Expert review, revision, and implementation of the guidelines are described next. The appendices, comprising the majority of the document, include (1) charts defining each dimension, its measurement, and cutoff scores; (2) examples of job tasks and critical incidents involving vision and hearing for each occupation; (3) matrices summarizing relevant vision and hearing dimension; (4) preliminary vision and hearing guidelines providing a proposed standard and rationale for each dimension, organized by occupation; and (5) revised versions of the vision and hearing guidelines.
