He can also qualify based on two index score in the 145+ range, such as VCI and FRI. Check those scores.
Also, there are other excellent GT resource organizations in addition to DYS, such as JHU's SET, for which the criterion is a score of 700+ Math or 630+ Critical Reading on the SAT before age 13 (or incrementally higher scores for each month of age past the 13th birthday). It's also free, and includes parent supports, consultation, and peer interaction opportunities. As an entering seventh grader, this is a perfect time to plan for the SAT for that purpose. You don't even have to register for it through them, or pay an additional fee beyond the standard College Board fees. Just send them a score report when you register for the test.
