Wow!! What a shame. Could you tell her that the GAI calc is important at your school to allow your child access to the appropriate curriculum for his achievement level and that if she does not calculate one, your child will not be allowed to participate??
You are PAYING her for this correct? Then surely her few minutes of time to run those numbers are part of the fee. It is a standard practice to calculate this when there is a "significant difference" (statistically) which is part of what she must report (and discuss) with his numerical results in his full report.
