Core-Plus Mathematics
Design, Development, and Evaluation Timeline
1992–2013

The Core-Plus Mathematics Project (CPMP) was initially funded in 1992 by the National Science Foundation¹ (NSF) to design, develop, and evaluate, and in cooperation with a publisher, nationally disseminate a Standards-based comprehensive four-year high school mathematics curriculum for all students. Creation of each course entailed a year of research, development and local pilot testing, regional pilot testing of the complete curriculum, revision, national field-testing, and further refinement prior to publication. Pilot testing included formative evaluation and field-testing included summative evaluation of the instructional materials and assessments.

Over the last 22 years, the curriculum has been systematically revised and updated in response to changing national standards for high school mathematics, reports from program users across the country and internationally, advances in technology and the most recent research on student learning. A detailed timeline of the curriculum design, development, and evaluation process follows.

1 Curriculum design, development, and evaluation was supported, in part, by the National Science Foundation (NSF) under Grant No. 9255257, No. 9618193, and No. ESI 0137718. Opinions, findings, and conclusions expressed are those of the authors and do not necessarily reflect the views of the NSF.
