This study explored the rates of grade retention among children with u
ndiagnosed learning disabilities. During the 1990-91 school year, data
were collected on 344 Michigan students who were referred for special
-education evaluation due to learning problems. Of the 201 students de
termined to possess a learning disability (LD), 71.6% had been retaine
d at least once before they were referred for special-education evalua
tion. Minority and urban LD students were more apt to be retained befo
re being referred for evaluation. Retained LD students were usually on
e year older than nonretained LD students at the time of special-educa
tion referral. Although retention among LD students did not appear to
be related to gender or grade placement, retained LD students generall
y exhibited lower levels of intelligence and weaker skills in reading
comprehension, writing, and math at the time of their referral. (C) 19
