2 Sigma is implemented in a network of partner schools, and supported by a team of 2 Sigma specialists.
The 2 Sigma team documents and applies the experiences of each school across the network. This allows constant optimization of the methodology for all involved schools.
Jeff Kiderman, Co-Founder
Jeff oversees the 2 Sigma roadmap and its collaborations with partners and schools. Prior to founding 2 Sigma, Jeff was a digital marketing consultant, helping Fortune 500 companies personally tailor their online and offline experiences to meet different customers’ needs.
Jeff earned degrees from both the Wharton School and the School of Engineering & Applied Science at the University of Pennsylvania. He is currently earning a Masters in Education at Columbia University. Jeff lives with his wife and son in New York, NY.
Avrumi Sacks, Co-Founder
Avrumi leads the development and rollout of the 2 Sigma model, using over two decades of experience as an educator.
Most recently, Avrumi served as Principal and Director of Education at the Hillel Academy of Pittsburgh, where he oversaw the education of children from pre-nursery through 12th Grade, and managed a staff of 70 educators and employees.

2 Sigma incorporates a variety of well-known online educational tools to develop and assess students’ language and math skills. These third-party tools have been carefully vetted and selected from hundreds of options nationwide, and piloted in controlled environments. Each tool is personalized, adaptive, cloud-based, and aligned to the Common Core State Standards. Learn how software fits into the 2 Sigma model
Curriculum Associates has been creating offline and online curriculum products for over four decades. iReady, their flagship online product, includes both diagnostic and instructional tools in reading and math.
Close to one million students currently use the iReady program.
iReady pinpoints students’ needs down to the sub-skill level, and ongoing progress monitoring shows whether students are on track to achieve end-of-year targets.
iReady then provides personalized student instruction targeted to students’ unique areas of needs to boost achievement, as well as data for educators with real-time insights for each student.
Lexia Learning, acquired by Rosetta Stone in 2013, has worked for the last three decades to improve student literacy through the use of technology.
Lexia Learning is one of the most respected reading technology companies in the world. Its Common Core-aligned Core5 product provides explicit, systematic, personalized learning on foundational reading skills. In addition, the product delivers norm-referenced performance data along the way.
Students using Core5 learn skills in sequence, logically building an understanding, while gaining competency and preparing for the next skill. The research-proven system predicts students’ year-end performance and provides teachers data-driven action plans to help differentiate instruction.
Mind Research Institute
The Mind Research Institute is a nonprofit started in 1998 by three University of California neuroscience researchers in order to revolutionize math education through visual learning.
Their research of how the brain learns best led to the development of Spatial-Temporal Math (ST Math), an instructional software tool that teaches math proficiency and problem-solving skills. The software uses a uniquely visual, non-language-based approach.
Its game-based approach enables students to use visual images over time to reason through problems and develop strong math skills.
The program contains approximately 140 leveled games per grade that teach math concepts, and materials are over 90% aligned with Common Core standards. The program is used as a supplemental tool for over half a million students nationwide. Many schools have used it to double or triple math proficiency growth.
Northwest Evaluation Association (NWEA)
NWEA is a global nonprofit educational services organization founded by a group of educators over four decades ago. NWEA’s Measures of Academic Progress (MAP) test is an adaptive assessment tool that compares and predicts student achievement and growth using normative and growth information.
MAP results are used to measure the growth of each student and to inform instruction using valid, reliable, and real-time data.
MAP tests are used by over 7,000 schools and over 10 million students per year.
