Part I of this report attempts to describe the system that was developed for local educational agencies by the Delaware State Department of Public Instruction to support classroom and curricular improvement in mathematics through the administration of an objective-referenced test in mathematics to grade four students. This system includes the development of ancillary services and products to support the use of the testing results. The testing materials and related products are part of the Delaware Educational Accountability System. The state level results are presented in Part II. Included is a description of Delaware mathematics strengths and weaknesses by strand and objective. Specific conclusions and recommendations are presented in Part III. The conclusions and interpretive comments were generated by the members of the Delaware Mathematics Advisory Committee. (Author/RC)
