To speak or not to speak ? that is the question.

We are coming to a cross road with KT. She is almost ready to graduate from speech. Now KT has an auditory processing disorder and well as problems with 's' , 'sh', 'ch' and 'j'. She sort of slurrs all of these together and squeezes air out the the sides of her mouth when she says them. She only does this in conversation, not when reading or repeating a word. If she does it in conversation she can quickly fix herself when reminded. What I can't decide is if we should discharge her for the summer and be done or keep torturing her a little longer ? If we discharge her chances are she will not qualify for speech later. However we could work on something else this summer in place of speech, that may be more beneficial.
