Advanced Content Class (6-12) -- Students are homogeneously grouped on the basis of achievement and interest in a specific academic content area. The district may elect to include students who are not identified as gifted but who have demonstrated exceptional ability and motivation in a particular content area. In that case, the local district must establish criteria and guidelines that identify students who will be successful with the advanced curriculum to be offered in these classes. (Identified gifted students may also be required to meet the specific achievement criteria.) Identified gifted students in the advanced content course may be counted at the gifted weight only if (a) the maximum size specified for gifted resource classes in State Board Rule 160-5-1-.08 CLASS SIZE is observed; (b) a description of the course curriculum (showing very clearly how the advanced course content, pacing, process skills emphasis, and expectation of student outcomes differ from the course more typical students at that grade level would take in that content area) is developed and maintained by the local board of education;
