Personally, I am not sure I'd take a kid with "issues" (of any sort, good or bad) into a brand new charter school with no record. It might sound good, and turn out to be a complete disaster. There's a chance it turns out to be great, but I'd personally rather go with something I know is mediocre than risk basically losing an entire school year in a bad school.
If you do want to go with the charter school I'd have a (long) list of very specific questions I would want answered - starting with how will they differentiate? What services will they provide for her dyslexia? How will they handle any accommodations she needs for her ADHD? How will they be evaluating her progress in regards to her dyslexia? Who will establish the goals she's working towards? Who will be providing the assistance to her and what are there qualifications? How will they handle a need for future grade/subject skips? Etc, etc.
