Abstract: Various embodiments for prescribing electronic resources based on observational assessments are described. One example system includes a communication unit for sending and receiving data, a recommendation engine, and an assignment engine. The recommendation engine receives observation data related to a target subject, identifies one or more electronic resources that correspond to the observation data, and provides data describing the one or more electronic resources for display to an observer. The recommendation engine is coupled to the communication unit to provide the data representing the one or more electronic resources. The assignment engine receives an assignment request requesting an assignment of at least one electronic resource from the one or more electronic resources to the target subject for completion. The assignment engine also assigns the at least one electronic resource to the target subject. The assignment engine is coupled to the communication unit to receive the assignment request.
