The Gray Diagnostic Reading Tests-Second Edition (GDRT-2)
has been revised and updated to reflect current research in reading. The GDRT-2,
a revision of the Gray Oral Reading Tests-Diagnostic (GORT-D), along with the
Gray Oral Reading Tests-Fourth Edition (GORT-4) and the Gray Silent Reading
Tests (GSRT), form the Gray reading test battery. The GDRT-2 assesses students
who have difficulty reading continuous print and who require an evaluation of
specific abilities and weaknesses. Two parallel forms are provided to allow you
to study a student's reading progress over time. Teachers and reading
specialists will find this test useful and efficient in gauging reading skills
progress.
The GDRT-2 has four core subtests, each of which measures an important reading
skill. The four subtests are: Letter/Word Identification, Phonetic Analysis,
Reading Vocabulary, and Meaningful Reading. The three supplemental subtests,
Listening Vocabulary, Rapid Naming, and Phonological Awareness, measure skills
that many researchers and clinicians think have important roles in the diagnosis
or teaching of developmental readers or children with dyslexia.
The GDRT-2 was normed in 2001-2002 on a sample of 1,018 students ages 6 through
18. The normative sample was stratified to correspond to key demographic
variables (i.e., race, gender and geographic region). The reliabilities of the
test are high; all average internal consistency reliabilities for the composites
are .94 or above. Other major improvements include: Studies showing the absence
of culture, gender, race, and disability bias have been added, and several new
validity studies have been conducted, including a comparison of the Wechsler
Intelligence Scale for Children-Third Edition (WISC-III) to the GDRT-2.
