CSU California Academic Partnership Program

The Mathematics Diagnostic Testing Project

The Mathematics Diagnostic Testing Project (MDTP) is a joint statewide project of the California State University and the University of California. MDTP develops, distributes, scores, and reports the results of diagnostic tests that measure student readiness for mathematics courses ranging from Prealgebra to Calculus. Diagnosing a student's mathematical strengths and weaknesses helps teachers focus on areas needing review to increase students' chances of success in mathematics, better prepares students for further study in mathematics, and keeps open many career paths. MDTP was established in 1978 and has received support from CAPP since 1985.

MDTP provides test materials and scoring services to California mathematics teachers who request them. Online and paper versions of the tests are available. Assistance in using test results to improve class development and instruction is provided by MDTP associates at 10 scoring sites around the state.

MDTP hosts user conferences for secondary teachers and faculty from community colleges and universities to help them better understand their studentsí needs and different approaches to mathematics instruction.

The MDTP website provides information on accessing tests, the regional sites and activities, and MDTP Newsletters: http://mdtp.ucsd.edu

A new report on teachersí use of MDTP results is now available. Click to read the Summary and Full Report commissioned by CAPP and prepared by Karen Volz Bachofer, Andrew C. Zau and Julian R. Betts of the San Diego Education Research Alliance (SanDERA) at University of California, San Diego. This study extends prior research and a report published by the Public Policy Institute of California in October 2011 which examined district-mandated use of MDTP in San Diego Unified School District and found strong and noteworthy gains.
