Modern where? In the US 15 is more common; anything else is "used
occasionally", if at all:

QUOTE:
Distribution

IQ scores are expressed as a number normalized so that the average IQ
in an age group is 100. In other words, an individual scoring 115 is
above average when compared to people in the same age group. It is
common practice to standardize so that the standard deviation (s) of
scores is 15 or 16 ( 24 is used occasionally as well ). Tests are
designed so that the distribution of IQ scores is Gaussian, that is to
say that it follows a bell curve.

http://en.wikipedia.org/wiki/Iq

In the furore following the publication of "The Bell Curve",
journalists invariably reported that the measured average IQ difference
between blacks and whites was 15 "or about one standard deviation".
They said this whether they knew what a standard dev is or not.

Another reference:

QUOTE:
Despite the fact that The g Factor is not primarily about race,
Jensen's discussion of g and race will strike many as being its central
theme. All the issues Jensen dared to voice in 1969 are still with us
today. Indeed, much of the opposition to IQ testing and heritability
research would probably disappear if it were not for the stubborn and
unwelcome fact that, despite extensive programs of intervention, the
mean Black-White difference in g does not diminish. Chapter 11 of The g
Factor fully documents that, on average, the American Black population
scores below the White population by about 1.2 standard deviations
(equivalent to 18 IQ points).
