why not test? DS tested a 150 at age 4.5 and tested again at age 8 or 9 at 160. does the 150 or 160 make a big diff on what the programs can do? no. Test now with the 140 and join DYS, there's a good enough reason to do it now! (BTW i only retested because we moved and the new gifted school needed current testing, less than 2 years old)
