"For
the
past
several
years,
I
have
been
involved
in
an
external
role
of
directing
and
verifying
research
projects
related
to
research
projects
conducted
by
your
company
to
determine
the
soundness
of
PDP's
assessment
devices.
I
have
also
served
as
an
outside
sounding
board
for
the
interpretations
of
such
projects.
I
am
pleased
with
the
high
standards
of
research
methodology
you
set,
not
only
initially,
but
also
in
ongoing
development.
It
is
heartening
to
find
a
business
that
values
accuracy
and
that
takes
additional
measures
to
insure
validity
and
reliability
with
their
products.
In
my
opinion,
PDP
has
taken
appropriate
steps
to
ascertain
the
validity
of
their
tests.
They
have
consistently
used
sound
experimental
procedures
to
make
these
determinations
and
are
continuing
these
activities
on
an
ongoing
basis.

Letter

Esq.
I
am
a
lawyer
specializing
in
labor
and
employment
law.
I
have
represented
and
assisted
many
Fortune
500
corporations.
Over
the
years,
I
have
assisted
clients
in
all
aspects
of
labor
and
employment
law,
including
recruiting
and
hiring
practices.
There
are
many
legal
issues
associated
with
psychological
testing
as
a
pre-employment
measure.
I
am
very
impressed
to
see
that
the
PDP
has
addressed
the
legal
concerns
with
such
testing.
I
would
like
to
compliment
and
commend
PDP
for
its
diligence
in
designing
a
psychological
survey
with
legal
integrity.
Specifically,
I
was
pleased
to
learn
that
(1)
PDP
is
thoroughly
and
accurately
validated
based
on
research
and
a
current
norming
population
of
3
million
people;
(2)
PDP
has
successfully
reinforced
the
already
solid
validation
study
through
its
Monograph
No.

research
and
documentation;
and
(3)
PDP
is
compliant
with
state
and
federal
discrimination
laws
as
supported
by
PDP's
Disparate
Impact
Study.
I
also
was
impressed
with
PDP's
extensive
and
ongoing
validation
and
research
practices
to
maintain
such
a
high
degree
of
continued
accuracy
and
quality.
I
also
applaud
the
PDP
for
its
focus
on
employees'
strengths
and
unique
attributes.
The
PDP
system
fosters
a
much
healthier
and
positive
corporate
environment
and
assists
employers
in
seeing
the
strengths
of
their
applicants
and
employees
—
as
opposed
to
their
perceived
weaknesses.
Keep
up
the
good
work!
