Did you have a written contract with the tester? Anything in writing stating what you would receive for the price you paid? Possibly a statement on their website, in a brochure, etc, to manage your expectations? It would seem that a good strategy/approach would be to hold the psychologist's office accountable to their own policies and statements.

Another approach may be to list out exactly what you are expecting to receive. This might include:
- All test scores from assessments administered to Xxxxx Xxxxxxx from dates xx/xx/xx to xx/xx/xx, including subtest scores
- Tester's observations
- Psychologist's interpretation of test and subtest scores, indicating particular strengths and weaknesses
- Any diagnoses
- Recommendations, including further testing, academic placement, instructional differences (IEP), accommodations (504)

You might wish to state that it was your understanding that all this information would be included in the full report, and was included in the price you paid on xx/xx/xx for the assessment processes.

You might wish to describe what you've received so far, the date you received it, what information was contained, what information was NOT contained, and also inquire as to the meaning of "High Superior" (which may also become clear when they send the information you have requested, above).
