Math Diagnostic Testing Project

MDTP (Mathematics Diagnostic Testing Project)

A free diagnostic tool designed to support secondary mathematics programs in California schools

MDTP is an intersegmental statewide project funded by the California State University, University of California and The California Academic Partnership Program. The program develops, distributes, scores, and reports the results of tests that measure student readiness for mathematics courses ranging from pre-algebra to calculus.

MDTP diagnostic readiness tests are used formatively in classrooms, departments, and schools to promote and support student readiness and success in college mathematics courses. 

  • Teachers use MDTP diagnostic tests to inform and enhance their classroom teaching practices.

  • Departments and schools use MDTP diagnostic tests to collectively shape instruction, assessment, support and intervention, and policy. 

MDTP Online Platform Upgrade

MDTP is excited to announce the successful upgrade of the MDTP online testing platform. While the new platform looks different, essentially, the functionality remains the same. Please review the MDTP Diagnostic Tutorials as needed to support this transition.

Additionally, the new platform includes new features that will benefit educators and students in efficiently diagnosing and preparing students for success in mathematics courses. These new features include:

  • Faster processing speeds
  • A single login page for students, faculty, administrator and placement users which can be found at the following link
  • Ability for users to pull side-by-side comparison reports to dynamically inform instruction

All MDTP online readiness test users will be automatically directed to the new platform.  Please contact your regional site staff or the Director’s Office at if you have any questions or need support using the new platform. 

To register for online testing, please complete the appropriate online testing registration form.

Frequently Asked Questions

  • Which MDTP test should I administer?
  • This is a list of suitable, existing MDTP tests that could be used to measure readiness for students moving up tot he following Common Core aligned classes in the fall. For more specific information on tests please visit the MDTP site 
    • Students Entering
      Test to Administer
      Math 6 or Math 7 7R40A15 or PR40A04
      Math 8 8R40A15 or AR45A10
      Algebra 1/Math 1 HS45A15 or AR45A10
      Geometry GR45A06
      Math II IS45A00
      Algebra II SR45A06
      Math III IT45A00 or SR45A06
      Precalculus MR45A08
      AP Calculus CR45A12
      AP Statistics MR45A08 and WRI
      Discrete Math MR45A08
  • When should I administer the test(s)?
  • Teachers often administer tests near the beginning of the course to help identify curriculum areas that need review, during courses to measure growth from the beginning of the year, and/or near the end of the course to help students prepare for the next mathematics course
  • How do I order testing materials?
  • Visit the main site and submit the form online, or call our office and someone will help you with your order (530) 754-9504
  • Is there a cost to use MDTP testing materials?
  • Generally, no. Materials and services are provided to California secondary schools for no charge. MDTP provides printed testing materials and test results reports at no charge to teachers, schools, and districts.
  • Does MDTP have written response questions?
  • Teachers can go to the link once orders are placed.
    For each item scored you will receive a copy of the item for reproduction and distribution to your students, an instructor's supplement page containing additional information about the question and ideas for classroom extensions of the question; the MDTP generalized scoring rubric applicable to all MDTP written response questions; and the specialized scoring rubric created specifically for that particular item
  • How quickly after I submit an order are the test materials available?
  • Per the conditions of the CSU/UC MDTP agreement, we do our best to process all orders usually within two days of receipt of requests. We can either mail the testing materials to you or you can pick them up in our office on the UC Davis Campus. Please take into consideration weekends and holidays when ordering materials to be shipped out.
  • Do you offer testing materials for non-English speakers?
  • Yes! We offer several test in Spanish: pre-algebra, algebra, geometry, and second-year algebra readiness. On the order form, let us know how many you will need.
  • How long does it take to receive the test results?
  • Per the conditions of the CSU/UC MDTP agreement, our office strives to have test results available within two days of receipt of answer sheets. Please do keep in mind that mail can take several days to get to our office. We can have test results mailed to you, or you are welcome to pick them up in Dutton Hall. Also please factor in weekends and holidays when anticipating turn-around times.
  • Does my county work with the UC Davis MDTP site?
  • The UC Davis site works with schools in the following counties: Alpine, Amador, Calaveras, El Dorado, Placer, Sacramento, San Joaquin, Solano, Sutter, and Yolo. If you do not see your school's county on this list, please visit
  • Is the MDTP test helpful with changes to the Common Core State Standards in Mathematics?
  • Yes! MDTP began developing readiness tests aligned to the new California Common Core Standards for Mathematics in 2013. With the creation of the Grade 8 Mathematics course and the change in expectations for what is taught in Grade 7 Mathematics and Algebra I, the MDTP Workgroup began assembling a Grade 7 Math Readiness Test (7R40D15), Grade 8 Math Readiness Test (8R40D15), and High School Readiness Test (HS45A15). The second year of field testing began in fall 2014, and the goal this fall MDTP released three new Common Core aligned tests: 7th Grade Math Readiness, 8th Grade Math Readiness, and High School Math Readiness (appropriate for Algebra 1 or Integrated Math 1 classes). In 2014, the Workgroup began work on two new tests for schools implementing the integrated pathway. These tests will measure readiness for high school Math II and Math II courses. If you would like to participate int eh 2015-2016 field testing and your school has already moved to align its math courses with the new CCSS, please contact

Test Results

Schools should help students interpret their individual test results in ways that best meet the students’ needs. In particular, each K-12 student who takes an MDTP test should be provided with a copy of the student letter that indicates the student’s score and identifies those topics in which more work is needed. Students whose test results indicate readiness for a mathematics course should be encouraged to pursue their mathematics education. They should also be cautioned that success in a course requires good study habits and persistence. Students whose test results indicate inadequate preparation for a particular course should be advised to develop readiness for that course either by individual study or enrollment in a course that will prepare them for it. They should not be counseled out of mathematics.

Since MDTP tests are designed to measure readiness for further mathematics study, no scaling of scores is provided. Raw scores are used for reporting to students and, when used as part of a placement procedure, for providing one reliable indication of the extent to which a student’s current mathematical proficiency matches the skills and knowledge needed for success in a course. Other indicators should also be used. Statistical analysis of test performance and subsequent course performance is a prerequisite to valid uses of test results for placement purposes. This analysis must be undertaken at each school and for each course to determine cut scores and counseling ranges. Moreover, the analysis should continue as long as the tests are used, as they should for any other matriculation assessment instrument.

The UC Davis site serves the following counties:  Alpine, Amador, Calaveras, El Dorado, Placer, Sacramento, San Joaquin, Solano, Sutter and Yolo. If you do not see your school’s county on this list, please visit
