The impact of age of entry and overage status on academic achievement was investigated. Reading and math scores for 41,141 South Dakota students in grades 2, 4, 8, and 11 were compared for students in age and school entry categories. Demographic information of the delayed student revealed that delayed students are typically white males with summer birthdays from middle to high-income families. The overall percentage of delayed students in the state of South Dakota is 17%, and the percentage of one-year overage students is 21 %. Analysis of the achievement data indicated that normal age and entry students scored significantly higher than students who were one-year overage and those who had delayed entry into school.
