Academic Results of 2 Sigma Classrooms
Pilot schools implementing 2 Sigma have demonstrated extraordinary academic gains in short periods of time. This is consistent with findings of prominent research studies on one-on-one instruction. 2 Sigma’s baseline assessments are administered three times per year using NWEA’s Measures of Academic Progress (MAP) test.
In the 2014-15 school year:
- 2 Sigma students made over 40% more progress in reading and over 90% more progress in math than the national average
- Over 95% of 1st & 2nd Graders in 2 Sigma exceeded the average US student’s growth in math
- Weak students - those who began the year below the 25th percentile nationally - jumped in reading from the 11th to 30th percentile, and leapt in math from the 12th to 51st percentile.
These early results demonstrate the power of one-on-one teacher instruction. This power is enabled by 2 Sigma, a methodology which makes it possible for teachers to spend the vast majority of their time one-on-one with students and provides the tools to maximize that time.

The 2 Sigma model makes strategic use of data for every student on a day-to-day basis. This gives unprecedented clarity regarding 2 Sigma’s effectiveness.
In one pilot of 385 students, 2 Sigma compiled data from:
- Almost 5,000 diagnostic assessments using MAP and iReady Diagnostics
- 40,000 completed math and reading lessons in iReady
- 100,000 completed literacy units in Lexia Core5
- Almost 2 million math puzzles solved in ST Math
In addition to helping teachers meet each student’s needs, this constant flow of data, together with educator feedback, enables constant improvements and refinements to the model.
