Depending on how old your son’s learning disability evaluation is, he should have the right to request reasonable accommodations to help him succeed in his job. Employers vary regarding how current they ask LD documentation to be, but if it’s was done within the last 5 years, it should be current enough. Some employers will accept older evaluations if the person was an adult when he or she was last tested.
Choosing reasonable and effective job accommodations varies depending on the individual’s areas of strengths and needs. For example, if your son has strong visual skills, it might help him to have written directions and/or flow charts for multi-step processes. If, however, he does better with listening than reading, it might be more appropriate to have an auditory recording of the steps that he can listen to as he works.
