The system of accesses, for each of a plurality of participants, network data, video data, audio data, processing data, and participation data. The system determines, for each of the plurality of participants, a signal strength score based on the corresponding network data, a background score based on the corresponding video data and audio data, a microphone proximity score based on the corresponding video data, a processing score for each of the plurality of participants based on the corresponding processing data, and an engagement score based on the corresponding video data and participation data. The system calculates the readiness score, for each participant, based at least on the corresponding signal strength score, background score, engagement score, and processing score, ranks the participants, and provides the ranked participants. ## Claims ### Claim 1 A method comprising: receiving at a device video data and audio data for each of a plurality of participants via a network;
