Normed for ages 4:6 to 7:11 (Usual age range is 4:6 to 5:11; Out of level age
ranges are 4:0 to 4:5 and 6:0 to 7:11).
This subtest assesses visual discrimination and awareness of spatial
orientation. It contains a total of 27 items, each scored as correct or
incorrect. Two starting points are available (age 4:0 to 5:11 start at item 1,
while 6:0 to 7:11 start at item 10).
Factor analytic findings
The Matching Letter-Like Forms subtest is considered a fair measure of g for
all ages (r = .55). Specificity is ample for all age groups.
Reliability and correlational highlights
Matching Letter-Like Forms is considered to possess medium overall
reliability (r = .85), with reliability coefficients ranging from .49 to .87
across all of the age groups It has moderate correlations with all other
subtests (mean r =.34) in the battery.
In the Broad stratum definition of abilities, Matching Letter-Like Forms is
considered to be a logical measure of Visual Processing (Gv). In the Narrow
stratum of abilities, it is considered to be a probable measure of Visualization
(VZ) (McGrew & Flanagan, 1998, p. 112).
Administrative and interpretive considerations
The Matching Letter-Like Forms subtest is described on pages 247-8 in the DAS
Administration and Scoring Manual and discussed on pages 64 and 65 in the DAS
Introductory and Technical Handbook. To aid examiners in the scoring of the
subtest, correct responses are highlighted in bold, green ink on the record
form. Be sure to record the child's actual responses so that you can later
