Is anyone aware of an up to date statement or table, from a reasonably reputable source, to define levels of giftedness on current IQ tests (ie the WISC-V, with or without extended norms).

So much of the literature about highly, exceptionally or profoundly gifted children still references the SBLM, or other ratio based formats.

When guided to read the work of Miraca Gross for example, how does a parent with a child who has current IQ scores make sense of where their child fits within the context of Miraca's work (obviously one will find stories which are more or less relatable in a qualitative sense).
