One license may be used per teacher. For example, if a Kindergarten license is purchased, one Kindergarten teacher may use the materials (if a school has purchased a license and the teacher leaves that position, the license may then be transferred to a different Kindergarten teacher). Even if a K-2 license is purchased, this license is still good for only one teacher. If it is detected that more than one teacher is using a license, access to the materials will be revoked immediately, as this is a violation of federal DMCA law. However, multi-teacher licenses are available for purchase.
