They actually have used her being at grade level or just a bit beyond on their tests as reason to say that she isn't gifted. It took over a year of working with the district to get a GT id in language arts only. We were told initially by the school that two IQ tests and private achievement testing were due to "good guessing" and that her times where MAPS have come out higher were also good guessing.
That is incredibly frustrating. Despite multiple outside indicators, they seem to be saying that only their specific tests are valid -- and even those are suspect if they don't provide results that fit the teacher's preconceived notion?! I hope that your DD will get a better teacher who understands her true potential next school year.
