You may wish to write a letter to the school (e-mail will do).
- Addressed and distributed to all names/titles on the letter and on previous correspondence regarding gifted testing.
- Acknowledging the letter which you received.
- Asking for copies of all test results. (Search for FERPA online or read a parent-friendly summary here, at wrightslaw.)

You may also wish to begin a binder of advocacy documentation at home, gathering pertinent information including correspondence with the school, notes taken during any phone calls or in-person meetings, test results, work samples, letters of recommendation, your child's detailed description of the testing process, print-outs of the school policies (often found in the school's website) and your current State Laws regarding education.

Like you, I also would not have offered the prior test results. I think the school may choose to dismiss them (as IQ scores tend to stabilize around 8 years old).
