I have the third edition of the IAS. We used it and were successful with our attempts. I think if you get yourself a copy, you could gear up to show them that their conception of the 75% is misunderstood. In reality, the 75% is a key component, but your child can still receive 2 points on that section for her score. 50%-74%, I believe receives 2 points. If less than 10 for that section then WHOLE GRADE is not recommended but they are still supposed to see what total score is and are encouraged to continue with the rest of the scale. The FINAL score is what they need to be looking at and based on the total score will say, single subject, enrichment etc. should be considered. I would challenge their understanding in a non-attacking manner and see if you can't get them to complete it to see the total final score. By quoting the exact verbage of how the IAS is to be used can be to your advanatage. What we did was do a "mock score" out of the sample one in the book at home so we could gauge what we thought they would score for certain things and see where her total score might come out. Even without one whole section of the AAAA we were still an excellent candidate. We did have to argue some points of their understanding of interpretation of the IAS verbage, but they had never used it before. In the end, our attempts were successful, so I can only encourage you to be VERY PREPARED in a non-threatening manner when presenting your side but I think you have a valid point. Without completing the scale, they are not using the tool in the way it was meant to be utilized. If you google it, you can find some samples of the form if you don't have the manual, but I would strongly encourage you to get yourself a copy. We were able to quote it in multiple ways and get it worked out the way we wanted.
