A system includes one or more server hardware computing devices communicatively coupled to a network. The one or more server hardware computing devices includes one or more processors and memory storing specific computer-executable instructions that, when executed by the one or more processors, cause the system to receive decision data describing usage conditions of an online proctored examination platform, determine, based at least on the decision data, a need for additional proctoring resources on the platform to meet a demand for proctoring resources, and send a request for proctoring services to each of one or more on-demand proctor users agreeing to receive requests to become available on the platform when the additional proctoring resources are needed. The instructions cause the system to receive a first acceptance message from a first on-demand proctor user of the one or more on-demand proctor users and, responsive to the first acceptance message, cause the first on-demand proctor user to become available as one of the proctoring resources of the platform.
