Hi LAF, Oh, flying to take the EXPLORE sounds expensive! Belin-Blank was my thought, as well. OR, could you find a tester in your area that could give one of the achievement tests for low-$? DS6 was too young for EXPLORE (DD9 took that), so we had him take the WIAT instead (since your DS is older, perhaps have him take the WJ?). It really was not that bad expense-wise (and well-worth it to get a read on where he was at).

Also, keep in mind that it appears that the EXPLORE criteria for DYS were recently raised.
