Here is what the website says about what is needed for a child to be qualified: (refers to the test scores)
Be administered when the applicant was at least 4 years old; AND
Meet or exceed the score guidelines listed; AND
Include an official, complete report with all pages attached. Reports for individually administered tests often include the testerís observations, tests administered, test scores, explanation of findings, and recommendations.

If your child meets the score guideline and your application is complete, it seems like that is all they are looking for. When we submitted our DD's scores, we included 2 pieces of work that showed her working above grade level as well as her qualifying scores because we were nervous about her getting accepted, but since her scores were high enough they didn't really look at the work we sent in too.
