Each district may provide, where applicable, an intensive acceleration class for any student retained in Grade 3 who was previously retained in Kindergarten or Grades 1 through 3. The focus of the intensive acceleration class should be to increase a student's reading level at least two (2) grade levels in one (1) school year. The intensive acceleration class should provide reading instruction and intervention for the majority of student contact each day and incorporate opportunities to master the Grade 4 state standards in other core academic areas.
