You mentioned above that she had low scores in receptive language on the CELF. This would be consistent with what you're reporting about her language comprehension and ability to follow oral directions. She also scored poorly on phonological memory, which is not only associated with dyslexia, but auditory processing, which can also affect how she comprehends oral language. Both the putative receptive language deficit and her documented relative weaknesses in reading comprehension would affect her ability to comprehend text.
I think you may already have the data necessary to document a receptive language deficit. Depending on your local school district situation, your school speech language pathologist should be able to update the receptive language testing, if that seems called for. You can request that the IEP team add this testing, even if you're mid-cycle. It's possible you may obtain a little additional information if you also pursue an auditory processing evaluation at a hospital. This is usually covered by insurance, with a referral from your PCP.
