The other aspect
is
that of “false negatives.”
These are the students who
are missed by the test. Only six children were rated “poor” by tho teachers who
were not identified by the test. This is less than
3%
of the total sample.
The larger degree of
error was in identifying more children
at
risk than actually were
at
risk.
This
seems the more acceptable error, since in
a
screening process such as this the goal
is to miss as few children as possible who might have difficulty in order to give
them the opportunity for special attention.
These results appear to be within acceptable limits.

THE RELIABILITY
OF
THE WISC-R PERFORMANCE
SCALE WITH DEAF CHILDREN

Though the Wechsler tests are widely used
to
assess the intellectual ability
of
henring impaired children, data on the reliability
of
the
WISC-R
with this
populatic
n
have heen lacking. The Performance Scale of the WISC-R was
administered to
59
preljrigually deaf children attendin
a
statesupported day
schod program. The reliability coefficients and stanfard eirors
of
measure-
ment were computed
for
each snbtest
and
for the Performance Scale
IQ.
The results compare favorably with those found
by
Werhsler with the stan-
dardization sample
For testing the intelligence
of
deaf and hard-of-hearing children, Vernon and
Brown (1964) indicated that the preferred instrument was the Performance Scale
of
the Wechsler Intelligence Scale for Children (WISC). Levine (1974) found that
the WISC was the most widely used test of menta1,ability with henring-impaired
children, despite a lack of evidence concerning the reliability and validity
of
the
Performance Scale with this specific population.
Since publication of these studies,
a new edition of the WISC has appeared. This new edition, the Wechsler Intelli-
gence Scale for Children-Revised (WISC-R) (Wechsler, 1974), has incorporated
several significant changes in testing materials as well
as
a restandardization
utilizing stratification variables based on the 1970 census.
’The
testing was done by Ms. Joanne Wolfson, doctcral student.. Appreciation is also due to
Mr.
Richard
Dirst, Superintendent of the Atlanta Area School for the Deaf, and h~s excellent faculty.
