The hypothesis that proportionately more boys than girls experience re
ading failure was tested on a sample of 708 children using both test-i
dentified and teacher-identified criteria. Test-identified reading fai
lure was defined by low scores on standardized reading achievement tes
ts given at the end of first and third grade. For Severely Reading Dis
abled (total reading score at the 10th percentile or lower), the ratio
of boys to girls was 1.4:1 at first grade and 1.3:1 at third. At both
grades equal proportions of boys and girls were represented in the Re
ading Disabled category (total reading score between the 11th and 30th
percentile). Teacher-identified reading failure criteria consisted of
enrollment in LD and Chapter One (remedial reading) programs at first
and third grades. Teacher-identified ratios of boys to girls in LD we
re 2:1 at both first and third grade, exceeding the test-identified ra
tios, while identification for Chapter One services did not show a gen
der difference.
