I am wondering if one is different than another? If the scores are generally the same? Is there a waiting period between the two? Our school district gives the WISC, and DD6 is going to be tested at some point this school year, but I am guessing it is going to be sometime in the spring (and if the school has their preference I am sure it'll be LATE spring). So, another school we are considering has to have the S-B, and we were thinking about in the meantime -- like sort of soonish -- doing that test, so that we know if she'd qualify for their HG immersion program, prior to waiting on our slow-as-molasses home school district. WDYT?
