Starting in 2006, CVSA began studying schools where achievement improved. The regional group of superintendents soon realized that how blocks of time were devoted to student learning appeared to influence achievement. Then, in 2010, CVSA officially charged a Task Force to review the current school year calendar, study alternative models, and recommend a calendar based on agreed-upon principles.
That Task Force referred to several sources as they created the proposed Calendar 2.0, including:
- Regional Educational Laboratory at EDC
- National Center on Time and Learning
