If the reading level is particularly what you'd like to advocate for, did your DD do a standardized type of achievement test as well as what you mentioned? Such the WIAT? That is helpful for particular academic areas and it's good to have something independent and national/international if the school doesn't see need for testing or only tests to a certain ceiling (for example my DD's public elementary school only tested reading levels to 5th grade. If a child gets every answer correct, the school doesn't explore further, they just say "5th grade level" - even if they know the child has a high IQ etc.)
