Day 1 of 3 · Tuesday, June 9, 2026 · Days 2–3 (June 10–11) pending · Source: Zoom (registrations counted as opt-ins) & iClosed (calls booked)
Day 1 pulled 32.7% of 17,618 registrants into the room — nearly 1 in 3, well above the typical mass-webinar benchmark. The room then held hard: once content started, live attendance climbed to a peak of 4,551 and stayed at or above 85% of peak for ~65 straight minutes.
The median attendee stayed 74.7 minutes — past the 59.7% mark of a two-hour-plus session. That's a deeply engaged audience, not a drive-by.
The drop comes in the final stretch — the close. Attendance fell from ~83% of peak to about 1 in 4 across the last ~15 minutes, and that's the window where the offer and the call-to-book land. That tail is the lever: every point of end-retention is more eyes on the offer, and more appointments into iClosed.
And Day 1 converted attention into pipeline: 133 calls booked in iClosed on the same day — 112 TeacherCon Next Steps and 21 Master’s admissions calls, booked across the closer team. That’s the direct downstream of holding the room through the close.
Days 2–3 (June 10–11) run next. A consolidated 3-day workshop report — unique attendees across all days, day-over-day retention, and total calls booked — can be generated once the workshop wraps.
Methodology. Registrations reflect the TeacherCon series registration (one form covers the 3-day workshop); Day 1 = June 9. Retention is measured from each attendee's Zoom join/leave timestamps, excluding the host. "% of peak" is the live headcount at each point relative to the session's highest concurrent attendance (4,551). The room opened ~28 minutes before content, so the curve is anchored to content start and "% of session" watch figures are conservative — median watch time is the truer stay-rate read. Show rate = attended ÷ registrations. Calls booked = appointments created in iClosed on June 9, 2026 (account/local time, America/Phoenix); the figure is 133–136 depending on the day-boundary time zone. All 133 are discovery/admissions calls.
