The prevalence of dyslexia among 100 children participating in a longi
tudinal study was examined. At age 10 years, The Dyslexia Screener (TD
S) test, a direct assessment of coding skills used in reading and spel
ling, was administered. The incidence of suspected dyslexia of borderl
ine or worse severity among boys and girls was not significantly diffe
rent, nor did males and females differ significantly in terms of TDS-s
uspected dyslexic types of severity levels. Results challenge the wide
ly held belief of an increased incidence of reading disability among m
ales and, in conjunction with findings from other recent studies, unde
rscore the need for establishing objective and reliable screening proc
edures in addition to teacher referral in identifying children in need
of special services. Possible factors mediating previous estimates of
incidence and the implications of these findings are discussed.
