CCx is the software developed and used by 1EdTech to enable the Characterization of products that have already achieved 1EdTech Certification. Characterization is the process by which the interoperability capabilities of a deployed product can be determined. The CCx software produces the characterization reports and is used for the comparison of such reports. It is this comparison which is used to identify the actual interoperability between the two characterized systems. This is the software that is used as a part of the 1EdTech Standards First Program.
