Where I am the term gifted is used a bit loosely and every school board defines their own cut off for a gifted label and whatever gifted programming they have.

My kids can go to one of 4 public school boards all with completely different gifted criteria. The lowest local cut off for a gifted label is is 96%ile (~127), the highest is 98%ile (~130). In one board you can get a gifted label at 98%ile but the bar for congregated classes is at 99.6%ile (~140). You end up with kids gifted in one school but not in the one across the street or the one down the road. Some of the boards are very specific and want VCI's above the cut off while others accept GAI or FSIQ so it isn't even just that some boards are easier than others.
