Once you have had her tested...
Schedule a mtg w/ the "team" at the school---the principal, the teacher, the speech pathologist, the special education teacher...
You want ALL the teachers to be on board and understand your daughters needs when it comes to school. You will want the gym teacher, the music teacher, the art teacher, the classrm teacher to know how to give your daughter the proper instructions that will help her learn best and nurture her self-esteem, too.
TLTC.org is a good website.
In the meantime, contact the school psychologist and tell her you want to set up a mtg w/ the speech pathologist.
