PG cutoffs are 145 or 152 depending on who you ask (without extended norms, which add another layer of complexity).
Have you considered asking for the Iowa Acceleration Scale? I found the school very resistant to considering outside scores, even though I know many people find them useful. It will depend very much on your specific school what is most helpful. Is there a gifted specialist you could consult? We found the district gifted specialist very helpful as an advocate because my daughter's scores meant much more to him than they did to her teachers and principals.
