In this study, a widely discussed issue, the achievement gap is examined in the light of (SAT scores gathered from the Chicago metro area schools. Achievement gap is further reconsidered by using the term 'gap production processes'. Tables and figures showing reading and math scores for both white and African-American 5"1 graders present several manifestations of the 'gap production process' in 10 districts in the Chicago metro area. A mixture of sample schools has been selected by taking into account the ethnic composition of any given school to ensure representativeness. As a result, it is found that depending on schools' location, 'gap production process' manifests itself in ways that vary from one district to another.
