Parents and schools often notice the need for addressing advanced mathematical performance in elementary students. Many gifted programs do not offer differentiated or accelerated mathematics as part of their elementary school options. In this report, the efforts of one school system to identify and serve the needs of highly mathematically able elementary students are reported. The process involved a multiple pilot program with increasing levels of involvement across the district over a 3-year period. Initially, a small group of students were allowed modest acceleration at one school. After each of the first 2 years, the identification and acceleration practices were refined. In the 3rd year, the program option was offered to students across the entire district.
