I have a 5 year old daughter who will turn 6 in March. She is currently in kindergarten and testing above grade level in reading and math. I'd like to have her tested for acceleration and possible placement in the gifted class. Should I hold off on the IQ test until she is 6? Would it make a difference whether she takes the SB-5 or WPPSI-III at age 5; or takes the WISC-IV as a newly turned 6 year old?
