The Center of Recruitment & Retention of Mathematics Teachers (CRR)

The CRR was created in August 2001 to address the shortage of qualified mathematics teachers at the middle and high school levels. Our goals are to retain mathematics teachers currently in the field and to attract college students to the teaching profession. 


The CRR's Vision

The CRR's Vision is an excellent mathematics teacher for every child.

The CRR's Mission

The CRR’s Mission is to attract, develop, and support new mathematics teachers, and engage current mathematics teachers in re-imagining mathematics learning through innovative programs, retaining high-quality teachers in mathematics education.


The CRR'S Values

The CRR's Values are Community, Growth, Service, and Empowerment.

  • We value our diverse community and are committed to building community through all events and programs.
  • We value growth, both within the organization as well as with each of our stakeholders and our community at large.
  • We value service, and we seek to be of service to our community, engaging with our community to improve mathematics education through each event and program.
  • We value empowerment, and we seek to empower our stakeholders to re-imagine mathematics education without boundaries.
The Center for Recruitment and Retention of Mathematics Teachers has provided excellent professional development opportunities for teachers in Southern Arizona for over 20 years. 
With this new partnership with the Arizona Department of Education (ADE), we will now be able to offer our services state-wide in support of our mission to ensure that every student has a highly qualified mathematics teacher.
This Partnership will allow us to provide free online and hybrid training opportunities to all K-12 Arizona teachers of Mathematics. 
 Free workshops are designed to deepen teachers' mathematical understanding, promote hands-on student-centered lessons, and examine alternative ways to present particular topics.

Our History


The Center for Recruitment and Retention of Mathematics Teachers (CRR) was founded by Dr. Fred Stevenson in 2001 to support Tucson area secondary mathematics teachers.

Sue Adams and Ann Modica, two outstanding former high school mathematics teachers, and leaders in Tucson area mathematics education, were recruited to be the co-directors.


Dr. Fred Stevenson, the founder of the CRR


The Center began by offering two programs:
  • A Tutoring in the Schools class to train and hire undergraduate University of Arizona students to use effective tutoring skills as they worked with classroom students. Due to the experience, some of these tutors decided to switch their current major to enter the Secondary Mathematics Education Program (SMEP) or the Teach Arizona program to become mathematics teachers
  • A New Teacher Induction Program paired new teachers with a supportive coach for a year. These new teachers also attend a monthly workshop designed to deepen their mathematical understanding and provide pedagogical training to develop effective classroom procedures and strategies.

Funding for the Center came from school district partnerships, private donations, and a National Science Foundation grant.


CRR hosted the first Mathematics Educator Appreciation Day Conference (MEAD). The MEAD Conference has grown to become the largest K-16 mathematics teacher conference in the state of Arizona.


CRR began hosting teacher workshops. Secondary mathematics content workshops were designed to deepen understanding and incorporate technology into lessons. Five 3 or 4-session workshops were offered on weeknights throughout the year.

Also in 2008, the Herbst Foundation provided an endowment to provide funding for two Saturday workshops per year. The Herbst Enrichment Mathematics Seminars (HEMS) are taught by exemplary classroom teachers who present meaningful content and model excellent teaching strategies. Stipends are paid to the teachers who attend. Currently the Herbst endowment funds five HEMS workshops each year. We are very grateful for the continued guidance and support from Lee and Arthur Herbst.


In April 2009, the first Advanced Placement Calculus Practice Exams were hosted. Both Calculus AB and BC Exams are given so that students gain experience with the types of questions asked and learn how the College Board exams are scored. In 2014, an AP Statistics Practice Exam was added to the event. Many thanks to Bruce MacMillan, Chris Yetman, and Josh Tabor for leading this effort.


In addition to workshops for secondary mathematics teachers, workshops were hosted for teachers in grades K through 6 to build an understanding of fractions, algebra, and geometry.


The CRR received funding to expand, revise, and improve the Tutor Scholar Program to focus on making the greatest impact possible through mathematics mentoring. The Student Thinking Enrichment through Mathematics Mentors (STEMM) came from those efforts. STEMM is an AmeriCorps program, supporting schools across the Tucson area with high-quality mathematics mentors and tutors (U of A students) in order to affect the greatest impact on youth. STEMM also engages the teachers in the New Teacher Induction Program as math mentors for three of their high-need students, providing a more intensive level of support for those students. The New Teacher Induction teachers also receive targeted biweekly mentoring from their Induction Coaches.


The Thomas R. Brown Foundation provided another grant to fund an expansion of the IMPACTS program to middle schools. The IMPACTS-MS Program provides teachers in grades 6 through 8 with experiences to further develop their content knowledge and pedagogical skills to help students develop the critical foundations for algebra.


The CRR pivoted all of its services online in response to the COVID-19 pandemic. The Arizona Department of Education (ADE) recognized the Center for its high-quality services and partnered with the CRR to expand the Center's services statewide. During the 2020-2021 academic year, thousands of teachers participated in CRR events, including over 1400 participants at the MEAD Conference from all 15 Arizona counties.


Arizona Superintendent of Public Instruction, Kathy Hoffman, formally acknowledged the CRR in both her State of Education and State of Special Education remarks to the Arizona legislature. In turn, ADE extended its partnership with the CRR for another year, meaning CRR services continue to be free to all Arizona teachers for the 2021-2022 academic year.


The Arizona Department of Education (ADE) recognized the important impact of the Center's services and extended its partnership with the CRR for an additional two years, running through September 2024. The Center also unveiled its Integrated Learning Classroom with flexible learning spaces, horizontal and vertical whiteboard surfaces, and hybrid technology to allow for both in-person and online participants.
