The meeting itself
How this is scored
Whether the call works: participant capacity, video and audio quality under load, screen sharing, breakout rooms, moderation, and what happens on a bad connection.
0 — Not a meeting tool: no multi-party video calls, only one-to-one calls or recorded video.
3 — Video meetings with screen sharing, chat and host controls such as mute-all.
5 — Meetings with a stated participant limit per plan, screen sharing, breakout rooms or a waiting room, and host moderation (mute, remove, assign co-hosts).
8 — Large meetings and webinars with published capacity limits, per-participant moderation and waiting rooms, layout control, simulcast or adaptive bitrate stated, and behaviour on constrained or mobile networks documented.
10 — Scale and control are engineering claims the vendor stands behind: capacity published per plan and per region, selective forwarding with adaptive quality documented, live streaming, hardware-room support, and diagnostics an admin can read after a bad call.
The Educator
Genuine multiparty HD meetings are documented — phones, desktops and room systems, 1080p content sharing, Active Speaker and Continuous Presence layouts — and the adaptive layering over Internet, LTE, 3G and 4G is the strongest poor-connection story I could ask for my dead-spot students. What I found no public information on is everything a teacher moderates with: breakout rooms, waiting rooms, mute-all or per-participant controls, and any participant capacity per plan. That mix of well-documented engineering and silent moderation places it just under the middle. 2 3 7
