Drawing on data collected during the Title I Demonstration Study, this report describes the extent to which Title I programs "expand and improve" the Title I student's regular curriculum. Background information is provided through an overview and discussion of the Title I legal framework and its effects on service delivery. A comparison of Title I and non-Title I services focuses on language arts instruction delivered at the elementary grade level. Taken into consideration is the amount and nature of Title I instruction. The influence of variables such as group size, type of instructor, degree of individualization, and location of instruction on student achievement, particularly in compensatory education programs, is examined. The basic conclusion reached is that districts can both comply with Federal laws and regulations and still provide services which do not necessarily "expand and improve" the regular curriculum. (EB)
