Note: in addition to attendance credit to maintain voting rights, voting on ballots is also required. The definition of a session is a sequence of consecutive Work Group meetings (meetings occur in defined timeslots such as AM1, AM2, etc.) starting with the opening plenary meeting and ending with the closing plenary meeting. As per the IEEE 802 LMSC WG P&P, participation credit for a meeting is granted when a participant attends at least 75% of a meeting, while participation credit for a session is granted when a participant attends at least 75% of the session meetings designated as required. Extra credit slots Do not count for attendance The common practice in 802.15 WG for in-person plenary sessions and interim sessions was that a session extended over four days and contained 16 meeting timeslots, with evening timeslots designated as extra credit , extra credit meeting attendance counted towards meeting attendance. Since most timeslots were scheduled with three meetings, a participant could only attend one of those meetings. This practice prevented a participant from attending many meetings that were in conflict with a preferred meeting. For electronic sessions, the 802.15 WG has experimented with sessions extended over seven days resulting in fewer conflicting meetings, allowing a participant to attend a wider diversity of meetings. One issue with this practice of extended sessions is that participants would need to attend many more meetings to achieve the 75% threshold for attendance credit if all of those meeting slots were designated as required. To put the attendance credit requirement for electronic sessions on par with in-person sessions, the 802.15 WG officers have designated 16 timeslots of the electronic session as required in accordance with IEEE 802 LMSC WG P&P. All other timeslots are still available for meetings and listed as extra credit; i.e. similar to the evening meeting timeslots of in- person sessions. As an example, the November plenary session consists of 38 scheduled meetings over 30 timeslots. Of those 30 timeslots, 16 timeslots are designated as required with the other 14 timeslots designated as extra credit. To achieve participation credit for the November plenary session, a participant needs to attend meetings in any 12 of the 30 (required or extra credit) yielding 75% of the time slots.
